A Lesson Plan for Teaching Rounding

A Lesson Plan for Teaching Rounding In this lesson plan, 3rd-grade students develop an understanding of the rules of rounding to the nearest 10. The lesson requires one 45-minute class period. The supplies include: PaperPencilNotecards The objective of this lesson is for students to understand simple situations in which to round up to the next 10 or down to the previous 10. The key vocabulary words of this lesson are:  estimate, rounding and nearest 10. Common Core Standard Met This lesson plan satisfies the following Common Core standard in the Number and Operations in Base Ten category and the Use Place Value Understanding and Properties of Operations to Perform Multi-Digit Arithmetic sub-category.   3.NBT.  Use place value understanding to round whole numbers to the nearest 10 or 100. Lesson Introduction Present this question to the class: The gum Sheila wanted to buy costs 26 cents. Should she give the cashier 20 cents or 30 cents? Have students discuss answers to this question in pairs and then as a whole class. After some discussion, introduce 22 34 19 81 to the class. Ask How difficult is this to do in your head? Give them some time and be sure to reward the kids who get the answer or who get close to the right answer. Say If we changed it to be 20 30 20 80, is that easier? Step-by-Step Procedure Introduce the lesson target to students: Today, we are introducing the rules of rounding. Define rounding for the students. Discuss why rounding and estimation are important. Later in the year, the class will go into situations that don’t follow these rules, but they are important to learn in the meantime.Draw a simple hill on the blackboard. Write the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 so that the one and 10 are at the bottom of the hill on opposite sides and the five ends up at the very top of the hill. This hill is used to illustrate the two 10s that the students are choosing between when they are rounding.Tell students that today the class will focus on two-digit numbers. They have two choices with a problem like Sheila’s. She could have given the cashier two dimes (20 cents) or three dimes (30 cents). What she is doing when she figures out the answer is called rounding- finding the closest 10 to the actual number.With a number like 29, this is easy. We can easily see that 29 is very close to 30, but with numbers like 24, 25 and 26, it gets more difficult. That’s where the mental hill comes in. Ask students to pretend that they are on a bike. If they ride it up to the 4 (as in 24)  and stop, where is the bike most likely to head? The answer is back down to where they started. So when you have a number like 24, and you are asked to round it to the nearest 10, the nearest 10 is backward, which sends you right back to 20.Continue to do the hill problems with the following numbers. Model for the first three with student input and then continue with guided practice  or have students do the last three in pairs: 12, 28, 31, 49, 86 and 73.What should we do with a number like 35? Discuss this as a class, and refer to Sheila’s problem at the beginning. The rule is that we round to the next highest 10, even though the five is exactly in the middle. Extra Work Have students do six problems like the ones in class. Offer an extension for students who are already doing well to round the following numbers to the nearest 10: 151189234185347 Evaluation At the end of the lesson, give each student a card with three rounding problems of your choice. You will want to wait and see how the students are faring with this topic before choosing the complexity of the problems you give them for this assessment. Use the answers on the cards to group the students and provide differentiated instruction during the next rounding class period.

Free Essays on Characterazation Of Jim

A role model is someone whom you greatly look up to; someone you model your life after. Anymore, it’s not too common to admire someone like Jim in the adventures of Huckleberry Finn. Yet, Huck looked to Jim as a father figure, and the only one to show him loyalty, faith, compassion, strength, wisdom, guidance, and above all else, love. Before their trip down the Mississippi, Huck’s only authoritative figure was Tom Sawyer. His father, Pap Finn, showed no sense of caring except to his next bottle of whiskey, and all other adults who tried to teach Huck were trying to educate in ways that couldn’t be done. Jim, on the other hand, takes the time to befriend Huck and help him make his own decisions, despite what society would say. After all, society looked down on slaves at that time. What would they think of a slave as a leader or a father figure? Jim teaches Huck many things as they travel South on the River. First at Jackson Island, Jim notices the nervous actions of the birds and predicts it will rain. When a violent storm moves upon the island, Huck realizes that he has experience and indeed knows what he is talking about. Jim also shows Huck his great sense of caring. When they were separated in the fog, he tells Huck that his â€Å"heart wuz mos’ broke bekase you wuz los’, en I didn’ k’yer no mo’ what bcome er me en de raf.† Also, his kindness is shown when Tom injures his leg towards the end of the story, and Jim refuses to leave him alone. Jim is seen as a heroic figure in Huckleberry Finn for his loyalty, care, and devotion to Tom and Huck. He also shines a light on the battle of slavery in the civil war era. All men are created equal and slaves are people, too. They have feelings for others, and deserve kindness just like everyone else....

Analysis of Walmart - Research Paper Example More than 90% of respondents said that Walmart’s leadership style is result centred and people focused (Foroohar, 2012). The managers interviewed confirmed that the people elected into leadership positions are servant leaders with sharp business minds, global outlook and a clear vision for the company. The company’s elevation was guided by leaders who constantly inspired their subordinates to work hard and steer the business to the next level of success (Roberts & Berg, 2012). The observation exercise revealed that leaders were understanding, inspiring, thoughtful, kind, and considerate and involved their subordinates in decision making. The subordinates were very happy with their leaders and perceived them as very helpful and pleasant to work with (Creswell & Clark, 2007). More than 90% of respondents said that transformational leadership was effective because it encourages and motivates employees to form common organizational goals, which has seen the firm transform from a small business to a multinational retail corporation. 87% of respondents said that leaders’ behavior increases performance by motivating, training and pushing employees to give their best. More than 90% of employees (respondents) were happy to work for the firm. The dissatisfied group gave reasons such as poor working conditions and low pay as major dissatisfiers The research also revealed that Walmart has good leadership that is guided by strong business ethics. Most respondents were satisfied with the company’s leadership and adherence to business ethics. However, there were several instances of unethical behaviour that were reported by respondents. For example, Wal-Mart was accused of unethical behaviour when it continued to buy clothes from Bangladesh which were banned for export. It was also involved in major financial scandals such as the Mexico scandal that involved bribery, fraud, and concealing evidence
