Lesson 1

Human Frequency Table

These materials, when encountered before Algebra 1, Unit 3, Lesson 1 support success in that lesson.

Lesson Narrative

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.
