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 make sense of problems and persevere in solving them as they explore two-way tables and how they organize data (MP1).
