Application Exercise 20.

Application Exercise 20.1: Data Analysis and Graphical Representations Apply your understanding of the learning from this chapter. When finished, submit your answers. Watch as the teacher leads upper elementary students into interpreting the results of the graph they have made of the circumference and diameter of a variety of circular lids (objects). The Ratio Pi Grades 5 and 6 https://mediaplayer.pearsoncmg.com/assets/_video.true/LessonStudyMathLens_TheRatioPiGrades5an d6_GH05051900_iPad Question Part 1 What type of graph have the students constructed? Part 2 Why is the teacher asking the students to show the best-fit line? Part 3 Although we only see a short section of the “interpreting the results” part of the lesson, what is the value of the discussion and sharing thoughts about best-fit line pattern? Application Exercise 20.2: Data Analysis and Graphical Representations Apply your understanding of the learning from this chapter. When finished, submit your answers. Watch as the teacher guides third-grade students with interpreting the data on a pictograph. Understanding Pictographs https://mediaplayer.pearsoncmg.com/assets/_video.true/met_pictographs Question Part 1 How does the teacher begin the discussion about the data on the graph? Part 2 What instructional methods does the teacher employ to promote student thinking about the graph? Part 3 In this lesson, the students’ analysis did not go beyond facts from the graph. How would you move students into making inferences about the data? Application Exercise 21.1: Simulations Apply your understanding of the learning from this chapter. When finished, submit your answers. Read the scenario and apply your understandings about using simulations to answer the questions. The fifth-grade teacher wanted to set up a simulation to have her students test what the probability would be of getting 7 out of 10 questions correct if you guessed on a true-or-false test. Question Part 1 What would the purpose be for using a simulation over an experimental probability task? Part 2 The first step in using a simulation is to identify the key component and assumption of the problem. Identify and explain what they are for this scenario. Part 3 The next step is selecting a random device for the key component. What would you recommend that they use for this activity? Part 4 An important part of a simulation is determining and defining what constitutes “one trial.” The authors recommend 10 times as one trial. Why is that appropriate for this simulation?
