A Lesson Plan for Teaching Three-Digit Place Value

A Lesson Plan for Teaching Three-Digit Place Value In this lesson plan, second-grade students further develop their understanding of place value by identifying what each numeral of a three-digit number stands for. The lesson takes one 45-minute class period. Supplies include: Regular notebook paper or a math journalBase 10 blocks or base 10 block stampsNotecards with the numerals 0 through 9 written on them Objective The object of this lesson is for students to understand what the three digits of a number mean in terms of ones, tens and hundreds and to be able to explain how they came up with answers to questions about larger and smaller numbers.   Performance Standard Met: Understand that the three digits of a three-digit number represent quantities of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Introduction Write 706, 670, 760 and 607 on the board. Ask the students to write about these four numbers on a sheet of paper. Ask Which of these numbers is largest? Which number is the smallest? Step-by-Step Procedure Give students a few minutes to discuss their answers with a partner or a tablemate. Then, have students read aloud what they wrote on their papers and explain to the class how they figured out the larger or smaller numbers. Ask them to decide what two numbers are in the middle. After they have had a chance to discuss this question with a partner or with their table members, solicit answers from the class again.Discuss what the digits mean in each of these numbers and how their placement is vitally important to the number. The 6 in 607 is very different from the 6 in 706. You can highlight this to students by asking them if they would rather have the 6 quantity in money from the 607 or the 706.Model 706 on the board or on an overhead projector, and then have students draw 706 and other numbers with base 10 blocks or base 10 stamps. If neither of these materials is available, you can represent hundreds by using large squares, tens by drawing lines and ones by drawing small squares.Afte r you do model 706 together, write the following numbers on the board and have students model them in order: 135, 318, 420, 864 and 900. As the students write, draw or stamp these on their papers, walk around the classroom to see how students are doing. If some finish all five numbers correctly, feel free to provide them with an alternate activity or send them to finish up another project while you focus on the students who are having trouble with the concept.To close out the lesson, give every child a notecard with one numeral on it. Call three students to the front of the class. For example, 7, 3 and 2 come to the front of the class. Have the students stand next to each other, and have a volunteer read the threesome. Students should say Seven hundred thirty-two. Then ask students to tell you who is in the tens place, who is in the ones place, and who is in the hundreds place. Repeat until the class period is over. Homework Ask students to draw five three-digit numbers of their choice using squares for hundreds, lines for tens, and small squares for ones. Evaluation As you are walking around the class, take anecdotal notes on the students who are struggling with this concept. Make some time later in the week to meet with them in small groups or- if there are several of them- reteach the lesson at a later date.

Abortion To Legalize or Not

Abortion To Legalize or Not Thesis The issue of abortion is controversial in numerous contexts. Even though it receives criticism from various groups, women should be allowed to decide on whether to abort or not. This should be a personal choice. This paper supports the issue of abortion based on research and critical scrutiny of the matter. However, other opposing arguments have been provided to defend why abortion should be prohibited.Advertising We will write a custom essay sample on Abortion: To Legalize or Not specifically for you for only $16.05 $11/page Learn More Women who have ever had unplanned pregnancy can testify why abortion should be legalized. Most people perceive fetus as a living human being. Hence, it is murderous to kill a fellow human being regardless of his or her age (Procon.org., 2012). Nonetheless, abortion should be legalized because it is every womans choice to have a child or not. Argument Some women conceive accidentally; however, it should be their choice whether to carry the pregnancy to term or not. People should be given chance to exercise their personal rights and make critical decisions that concerns life. As stated in the American Journal of Psychiatry, abortion is a medical procedure. In this context, physicians should respect the patients right to freedom of choice. Meaning that no matter the stance on the clinic, the public, or the government, it is every woman’s right to choose whether or not to give birth. External influences are not necessary in this context. This is a vital consideration. Women should not practice abortion just because they do not want to take responsibility for their actions. However, making abortion illegal will make people to raise children when they are not prepared to do so. Some women or parents are not ready to provide their children with all the love and development they deserve. The child will be raised in an unloving home and become a person who does not know how to love. Perhaps, such c hildren might develop unwanted behaviors or become criminals. Statistics indicate that most pregnancies are unintended. Pregnancy requires well-scrutinized considerations, preparation, as well as planning. Logically, why illegalize something that may help a person so much? Concurrently, children conceived out of rape or incest can be considered highly unwanted’. It is vital to establish, ratify, and embrace modest abortion reforms to have a significant effect on the matter. If the child is unwanted by the person who is supposed to love him or her the most, why would you force someone into this circumstance?Advertising Looking for essay on health medicine?

Get your first paper with 15% OFF Learn More No one should endure the shame and humiliation of the traumatic event of rape or incest by bearing and rearing child who was the outcome of it (Procon.org., 2012). If a mother is denied an abortion due to its illegality, that mother then will be forced to go through the pregnancy, the labor, the birth, and the raising of an unwanted child. What a disgrace? Another reason why abortion should be legalized is that women still sneak to do it even if it has been illegalized. Consequently, some go to unspecialized health parctioners who do not do it perfectly and successfully. In fact, some women have died due to unsuccessful abortion attempts. Due to the illegality of abortion, some women or ladies resort to quacks who are barely specialized in executing abortion processes. Such deaths and health complications can be averted if only abortion is legalized (Ainsworth Hall, 2011). Additionally, it is improper to use contraceptives due to health complications they might create. Precisely, people should be allowed to abort if conditions demand so. The fact that abortion still occurs even when it has been illegalized should be a global concern. Governments should allow citizens to make their own choices regarding the matter. Another factor is that some minors (young girls) conceive while still studying. This occurs either at elementary school level, secondary, or college levels. Evidently, such students are not ready to be parents. They must first pursue their educational ambitions for a better future. However, it is obvious that once a young girl (who is still studying) is pregnant; her educational ambitions might be doomed. In fact, some end up dropping out of school. Hence, illegalizing abortion is a hindrance to â€Å"girl child† education. People must accept that mature ladies can conceive and become pregnant at any time provided they play an unprotected sex. This is a considerable provision when scrutinized critically. It is vital to understand the provisions of abortion before rendering it illegal. Notably, institutions and human rights lobby groups are always fighting against birth control and abortions. However, it is vital to ask whether the â€Å"morning after pill† is included in this controversy?Advertising We will write a custom essay sample on Abortion: To Legalize or Not specifically for you for only $16.05 $11/page Learn More Is it because the concerned ladies do not know that they are pregnant yet, or is this the reckless and careless behavior of a female? No one talks about this point; however, it is believable that if you can recklessly have sex and then take a â€Å"morning after pill† the following day, why not make that the illegal form of â€Å"birth control† (Weitz, 2010).. Abortion should be legalized in order to formalize the entire process. Women should be at liberty to make choices on whether to carry a baby to term or not. After all, they are the ones who will be burdened by the entire pregnancy atrocities. Everybody needs a child and it is not anyone’s desire to kill; however, a situation might force. Another argument why abortion should be legalized regards the health condition s of some women. One might conceive; however, her health status might not allow her to carry the baby to term. Either, she can die or undergo an acute miscarriage. This might interfere with her life despite the need to carry the pregnancy for the expected 9 months. Just think of the deaths that would occur if abortions were illegalized. One would not only be killing the â€Å"child† but the mother also. Although the notion of women using contraceptives is a good one; however, not all women can afford contraceptives so often. So what happens when it comes to not being careless but being unable to afford the medical bill regarding maternity postnatal services? Another validation for abortion is that it gives parents the right not give birth to children with health defects such as Down syndrome and cystic fibrosis. Anyway, why should parents have a child with these conditions? No parent or child should be forced to go through that. This is a considerable provision in the context of pregnancy and birth control. Motherhood should never be a punishment. One should indulge in it when ready both psychologically and physically. Concurrently, abortion is usable as a population control method. If a person is not ready to have a child, both mentally and financially, having an unintended child can lead to numerous atrocities. These incorporate malnutrition, lack of proper medical attention, poor educational services, and starvation. Precisely, one cannot provide sufficiently for the concerned child.Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Counter-thesis and counter-argument Abortion is illegal since it denies the fetus a chance to live. It is improper to legalize abortion as demanded previously. This is a transgression of the highest order. In fact, it is not only a crime but a murder also. It is advisable to carry pregnancy to term so as to bring forth a new life. Additionally, abortion might kill the mother if not well executed. Hence, why should someone risk aborting a child in order to die in return? In fact, one should not engage in unprotected sex to get pregnant and abort in return. This is a considerable provision in various contexts. It is vital to agree that rearing unwanted children might be humiliating; nonetheless, it is improper to abort a life. This is not only malicious but criminal in nature. Precisely, abortion should be illegalized in various contexts. Religious views such as the 6th commandment of the Old Testament (Thou shall not kill), plays a critical part in the views of pro-life representativ es. There are also thousands of deaths that stem from unsafe abortions that happen yearly as mentioned earlier. Abortion should be illegalized while women should be urged to use contraceptives as the recommended birth control measure. Additionally, statistics has it that about 10% of the 1.6 million women experience cruel emotional ordeal after aborting (Cung, 2012). This is due to the fact that abortion causes various health complications to the concerned mothers. For instance, it is possible to experience damaged cervix, pierced uterus, hemorrhage, as well as other acute infections associated with the process. Some mothers cannot even give birth again in the future. Another concern is that a baby can survive an abortion and this might be devastating to the mother. Concurrently, the baby might develop some deformities due to the attempted murder. Such incidences are difficult to handle. In fact, there would not be the thousands of maternal deaths every year if abortions were legal and women were not afraid to get a safe and healthy abortion. It is arguable whether those who abort should receive the same penalty that they give the baby (killing innocent beings). Abortion can also lead to the killing of future leaders. For instance, who knows what the aborted child would have been in case he or she was given a chance to live? Response to counter-thesis Agreeably, all arguments supporting the illegalization of abortion are obsolete and doomed. For example, there are modernized health facilities that can be used to carry out the entire process. This thwarts the fact that abortion can cause severe health complications. The most important thing is that abortion should be practiced in designated health facilities upon legalization. The whole process can be done safely minus risking the mother’s life (Durand, 2009). Additionally, illegalizing abortion will not avert the vice absolutely. In fact, some women will slither to do it illegally, which is even worse. This is a considerable provision in various contexts. It is vital to agree that rearing unwanted children might be humiliating; nonetheless, it is improper to abort a life. References Ainsworth, S. Hall, T. (2011).

Close analysis to the film Fight club Essay Example | Topics and Well Written Essays - 1000 words

Close analysis to the film Fight club - Essay Example As in most cases, the ending of a film plays a key role in affirming the running theme of the film to the intended audience. Fight Club does not disappoint and lives up to the expectation of the audience who are thrilled through the entire film. Scholars have identified Fight Club as a good example of conformity which is a concept that is determined by those around your circles (Wartenberg, 2012). The film seeks to analyze the extremes of conformity and the society’s approach towards real human connections that are pivotal to the emotional well being of an individual. On the contrary, non-conformity is speculated to lead to alienation and rejection of an individual by the society. In extreme cases, it might lead to isolation. Being isolated in the society is the worst thing that can happen to an individual who values associated with others, but conformity denies them the chance of socialization hence isolation. The film justifies the attempts of characters to move out of the violence that ensues during each and every encounter of the Fight Club because of the urge to break out of their roles that they have in the community to unleash their anger. The pain just like anger demands to be felt in different ways among these is violence. Therefore, this paper will provide an analysis of visuals, sound, themes and motifs. Also, it will seek to provide a clear and concise analysis of the film’s significance as it further interprets the film’s meaning to the reader. Fight Club falls under the romantic comedy because it relates to the characters attitudes and it strives to achieve a healthy relationship. In most instances, a lot of behavior which seems unhealthy and harsh to each other is prevalent, but this does not work for them because both characters are out on the extreme end of their characters. The narrator is out for intimacy, but avoids it with by using

Steriodogenesis has a common pathway but hormonal steriods are Essay

Steriodogenesis has a common pathway but hormonal steriods are secreted in a strongly cell specific manner. Discuss - Essay Example Steroidogenesis takes place in endocrine glands like the adrenal and gonads.P450side chain linked cleaving enzyme get involved in the interconversion of cholesterol to Carbon18, Carbon19, and Carbon21 and this is the committed step of Steroidogenesis (John 1994, p.33). HMG-CoA or the mevalonate pathway generates isopenteyl pyrophosphate and dimethylallyl pyrophosphate which serve as precursors for steroidal hormones biosynthesis. Isopenteyl pyrophosphate and dimethylallyl pyrophosphate become joined forming geranyl pyrophosphate that becomes lanosterol (Mary 2011, p.55). Lanosterol undergoes Steriodogenesis transformation to form other steroids. All steroid hormones in humans follow this pathway, but not all steroids are hormones (John 1994, p.77). Steroid hormones are crucial for proper functioning of the body. They get synthesized from cholesterol which is also a component of the cell membrane thus the hormone is able to enter the cell and bind to its receptor. Steroid hormones get classified as androgens, estrogens, progestins, mineral corticoids and glucocorticoids. Both estrogens and androgens get generated by the gonads and affect sexual development. Progestrins mediate the menstrual cycle and pregnancy. Excretion of water and salts by the kidney get regulated by mineral corticoids while lipid carbohydrate and protein metabolism become affected by glucocorticoids. Steroid hormones become synthesized when they are need. The brain releases a signal when the body wants a certain protein synthesized or needs a certain process done (John 1994, p.78). These signals get transmitted via the intermediary hormones in other words through trophic hormones. Once released, they act on the central nervous system and the peripheral target tissues (Richardb2010, p.67). One can regulate the amount of steroid hormone secretion by regulating the amount of cholesterol produced because cholesterol is the precursor for these hormones. The adrenal cortex has three main tissue re gions: the zona glomerulosa, zona fasciculate, and zona reticular is. These zones are histological and enzymatically distinct and the exact steroid hormone secreted depends on the enzymes present (Reginald 2010, p.34). Adenocorticotropin (ACTH) hormone regulates hormones produced at the zona reticularis and zona fasciculata (Donald 2010, p.56). The hypothalamus releases ACTH in to the blood stream then it become carried to the adrenal glands where it binds to ACTH receptors on the cell membrane activating adenylate cyclase with production of cAMP (second messenger).This leads to ultimate secretion of cortisol. When the body needs to accumulate more sodium, angiotensinogen get released from the liver and it become to angiotensin( i) and later angiotensin (ii) that bind to the cell membrane receptors which get coupled to the phospholipase c of the zona glomerulosa (John 1994, p.32).This leads to secretion of aldosterone; a mineral corticoid. Aldosterone leads to sodium retention by fa cilitating gene expression of messenger RNA for sodium-potassium ATPase which is responsible for reaccumulation of sodium and potassium. Gonadol steroid hormones become secreted by the testis and ovaries. The important hormones in this category are the estradiol and testosterone. Luteinizing hormone stimulates testosterone production in men by binding to Leydig cells. Androgen binding protein transports testosterone sertoli cells which convert it to

Gotham City the residents reported that the street prostitution Assignment

Gotham City the residents reported that the street prostitution Discussion - Assignment Example the offender, suppression of any opportunity that the offender may have and hardening the situation making it difficult for the offender to do crime(Ikerd, 2010). The scenario provide us with an opportunity to probe some questions; why are the people of Gotham city not bothered with prostitution in the area? Why do the residences indulge in prostitution? What are the factors that make prostitution easy? After answering the questions, clear and well planned method can be employed in curbing the act. Some specific methods like; using informants, sweep of the area, saturation patrol, profile interview, operation indent and installing visible cameras can help in curbing the act. These are secondary methods, and the primary method is the best. It involves gathering intelligence unto why the community members indulge in the practice, then that the primary drive is handled. The local business people should be kept in mind while handling this matter, because some may argue that prostitution is what is making them have customers, and perhaps that is the reason people of Gotham are not concerned with prostitution. In conclusion there must be professional analysis to help in managing crime without infringing with anyone’s

The Tragedy Of Macbeth Two Faced Macbeth

The Tragedy Of Macbeth Two Faced Macbeth The Tragedy of Macbeth, a play by William Shakespeare is a tragedy of death and dishonesty surrounded by the noblemen of Scotland. The two main characters are Macbeth, the Thane of Glamis and his wife Lady Macbeth. The play focuses around the conflict in Scotland at the time between the King and rebellious Scotsmen. After hearing about his prophecy from the three witches, Macbeth stops at nothing to accomplish his goal. Macbeth eliminated anyone that is in his path, even his dear friends. Macbeth is facing obstacles in his public life as well as in his private life. In his public life, he is a brave and respected nobleman who has the trust from others as well as King Duncan. In his private life, he ultimately comes face to face with death because of his greed and desire. His private life differs from his public life in many ways; his private life consists of poor decisions as well as greed and guilt, this eventually leads to the downfall of Macbeth. Macbeth is an ambitious nobleman w ho has a tendency to self-doubt; however he is also a two faced, selfish murderer whose gone mad hungry for power. Macbeth demonstrates himself in public to have fair character at the start of the play in difference to his foul self later on in the play. Macbeth characterizes a character of loyalty and heroism that proves the fairness of his character. In the play Macbeth exhibits two different faces; he portrays a different personality in private and in public. Macbeths ambition is his true tragic flaw, it causes his downfall. Macbeth speaks to himself saying, à ¢Ã¢â€š ¬Ã‚ ¦On which I must fall down, or else oerleap, / For in my way it lies. Stars, hide your fires; / Let not light see my black and deep desiresà ¢Ã¢â€š ¬Ã‚ ¦ (1.4.50-56). Malcolm, the son of King Duncan, is proclaimed Prince of Cumberland this means he is also the heir to the throne of Scotland. Macbeth is willing to push all his principles aside. He knows that murdering King Duncan in order to become King of Scotland is wrong. This is why he says it is necessary to conceal his black and deep aspirations. Macbeth also citied tha t, à ¢Ã¢â€š ¬Ã‚ ¦To prick the sides of my intent, but only / Vaulting ambition, which oerleaps itself / And falls on th other (1.7.25-28). Macbeth confesses that the he only thing that is motivating him to kill King Duncan is his ambitions. Macbeths conscience bothers him throughout the story it is prohibiting him from forgetting all he knows about right and wrong. Here, ambition portrays as something ugly and dark. Macbeth quoted that, Away, and mock the time with fairest show/ False face must hide what the false heart doth know (1.7.81-82). Macbeth and Lady Macbeth are going over the plan to kill Duncan. Macbeth tells Lady Macbeth to go out there and entertain their guest and make them feel like their having a splendid time. They do not know that this is all part of their plot to kill King Duncan. Macbeth is concealing his true identity and his true intentions. His ambitions ultimately lead to his catastrophic downfall. In private, Macbeth exemplifies a sly and selfish person. Macbeths private self is influence by the three sisters prophecies and by Lady Macbeth in his purpose to kill. Lady Macbeth accuses Macbeth of being weak and not having the guts to kill King Duncan. Macbeth replies to her saying, I dare do all that may become a man; / Who dares do more, is none (1.7.47-48). Macbeth is saying that he can only do what is right for a man to do and if he dares to do anymore than he is not a man at all. He does not want to do anymore, but he is pressured by Lady Macbeth. She even questions his manhood. She thinks Macbeth is à ¢Ã¢â€š ¬Ã‚ ¦too full o the milk of human kindness (1.5.16). Macbeth is mentally weak; this is how Lady Macbeth easily influences him. Her strength encourages him at the start. Lady Macbeth insisted that Macbeth, Look like the innocent flower, / But be the serpent under it (1.5.67-68). Macbeth is acting innocent like a flower, but underneath that innocent flower be the serpent that is waiting to attack. To King Duncan, Macbeth is his innocent and loyal friend, when actually he is the enemy and a venomous man. This shows that looks can be deceiving. Macbeth is mentally a weak character that undertakes a drastic psychological change through the play. However, Macbeth then realizes what he has done and becomes guilty. He continues his murderous acts to persuade his dream of becoming King of Scotland. His guilty conscience causes him to hallucinate. Macbeth begins to think that he cannot sleep, Methought I heard a voice cry Sleep no more! Macbeth does murder sleep the innocent sleep, (2.2.33-34). Macbeth believes he cannot sleep because he has killed an innocent. Macbeths conscious sees Macbeth an evil person now and the evil Macbeth will only continue do evil actions. Macbeth believes that he still has the blood of King Duncan on his hands, Will all great Neptunes ocean wash this blood / Clean from my hand? (2.2.57-58). The blood on Macbeths hands symbolizes his guilt on him for murdering Duncan. Macbeth thinks that the whole ocean would not be able to wash away evidence of his guilt. His private life and doing causes him to feel guilty he quoted, I am in blood / Steeped in so far that, should I wade mo more, / Returning were as tedious as go oer (3.4.136-138). Macbeth is saying that the situation is already at a bad standpoint and he would like to get the situation over with because he is sick of waiting and living in guilt. He realizes that finding out other bad thing would not make the situation worse because he would still be standing in the same situation. He ends up with a blameworthy sense of right and wrong. His private life consists of poor decisions as well as greed and guilt; this eventually leads to his downfall. In The Tragedy of Macbeth, Macbeth ultimately faces obstacles in his public life as well as in his private life. At the end of the day he comes face to face with death because of his greed and desire. His private life differs from his public life in many ways; his public life consists of loyalty and honor in contrast with his private life that consists of poor decisions as well as greed and guilt, this eventually leads to the downfall of Macbeth. This shows that Macbeth, an ambitious nobleman can also be a two faced, selfish murderer who stops at nothing to become king and gain power.

Cryogenics And The Future :: essays research papers

Cryogenics and the Future Cryogenics is a study that is of great importance to the human race and has been a major project for engineers for the last 100 years. Cryogenics, which is derived from the Greek word kryos meaning "Icy Cold," is the study of matter at low temperatures. However low is not even the right word for the temperatures involved in cryogenics, seeing as the highest temperature dealt with in cryogenics is 100 (C (-148 (F) and the lowest temperature used, is the unattainable temperature -273.15 (C (-459.67 (F). Also, when speaking of cryogenics, the terms Celsius and Fahrenheit are rarely used. Instead scientists use a different measurement called the Kelvin (K). The Kelvin scale for Cryogenics goes from 173 K to a fraction of a Kelvin above absolute zero. There are also two main sciences used in cryogenics, and they are Superconductivity and Superfluidity. Cryogenics first came about in 1877, when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure"(McClintock 4). After Cailletet and Pictet, a third method, known as cascading, was developed by Karol S. Olszewski and Zygmut von Wroblewski in Poland. At this point in history Oxygen was now able to be liquefied at 90 K, then soon after liquid Nitrogen was obtained at 77 K, and because of these advancements scientist all over the world began competing in a race to lower the temperature of matter to Absolute Zero (0 K) [Vance, 1-10]. Then in 1898, James DeWar mad a major advance when he succeeded in liquifying hydrogen at 20 K. The reason this advance was so spectacular was that at 20 K hydrogen is also boiling, and this presented a very difficult handling and storage problem. DeWar solved this problem by inventing a double- walled storage container known as the DeWar flask, which could contain and hold the liquid hydrogen for a few days. However, at this time scientists realized that if they were going to make any more advances they would have to have better holding containers. So, scientists came up with insulation techniques that we still use today.
