The mathematical purpose of this lesson is for students to recall shapes of data distributions. In earlier grades, students were introduced to the shapes of data distributions (bell-shaped, uniform, symmetric, bimodal, and skewed) and how to use the shapes to interpret characteristics of the data set. In the associated Algebra 1 lesson, students describe distributions of data and describe the center of the distribution. In this lesson, students will distinguish between the various data distribution shapes, which will be useful in a later lesson when students create statistical questions from shapes of data. Students will have a refreshed sense of how to interpret the data from its distribution shape. 

In this lesson, students look for and make sense of structure (MP7) when finding distance on a number line, critique the statements given about the shape of distributions (MP3), and attend to precision (MP6) when describing the shape of distributions.
