Lesson 2
Patterns that Repeat
Lesson Purpose
Lesson Narrative
In an earlier lesson, students analyzed and described features of patterns that followed a rule. In this lesson, students do the same with designs with shapes that repeat according to a rule. Students begin by examining the patterns visually. They look for structure and make use of it to extend the patterns (MP7). Later, they represent each shape in the pattern with numbers and reason about the repetition mathematically—by using operations and observing the properties of the numbers (MP2). The third activity is optional as it provides an opportunity for extra practice.

Teacher Reflection Questions
In an upcoming section, students will learn to multiply multi-digit numbers. What do you notice in their work from today’s lesson that you might leverage in that future lesson?
