DIFFERENTIATION IN ACTION

Skill Building

From Activity 16.3: MLR 3 Clarify, Critique, Correct. Use this routine to help students clarify a common misconception when creating a box plot from a dot plot. Display a box plot with the correct median of 15, but use 11 for Q1 and 22 for Q2, which are the values students might calculate if they did not average the two middle numbers. Invite students to work with a partner to identify the error and write a correct response. Look for and amplify mathematical uses of language involving the shape, center and spread of the distribution. This will help students affirm their understanding of how to use box plots and dot plots to graphically represent a numerical data set. From Lesson 9 “Are You Ready for More?”: Server F, working 7 hours, offers to join the group of five servers, sharing their workload. If server F joins, will the mean number of hours worked increase or decrease? Explain how you know.
