Lesson objective: Collect, organize, and represent data based on like traits.

This lesson helps to build procedural skills with organizing and representing data. Modeling with two-sided counters is used here because it supports students as they collect data and create a visual representation of data in an organized manner. This work develops students' understanding that data can be organized into groups of like traits and recorded to show how many data points are within a group in the set.

Students engage in Mathematical Practice 4 (Model with mathematics) as they collect data using the counters and create visual representations to record their data.
