## Reflection: Discourse and Questioning Arithmetic Means - Section 1: Opening

This lesson is a great opportunity for students to practice a few standards of mathematical practice. First, when they share their process for finding arithmetic means, they will be using SMP 3: Construct viable arguments and critique the reasoning of others. As they recognize the repeated operations they may be doing implicitly to find the mean, they have the opportunity to practice SMP 8: Look for and express regularity in repeated reasoning.

# Arithmetic Means

Unit 6: Arithmetic & Geometric Sequences
Lesson 7 of 10

## Big Idea: What number can I add to make this sequence work? Students find the missing terms in arithmetic sequences. They generalize their work to write equations for arithmetic means.
