The mathematical purpose of this lesson is to create and interpret data from a two-way table. Previously, students used tables to organize and interpret data. Students also encountered two-way tables in grade 8 when they used them to summarize data and find associations between variables. This lesson prepares students to use two-way tables to interpret and analyze data from a two-way table in the associated Algebra 1 lesson. Students look for and make use of structure (MP7) when they practice changing perspectives to focus on various aspects of two-way tables.
- Create two-way tables
- Use a two-way table to interpret data
- Let’s use tables to organize data.
