Lesson 2

More or Fewer Pattern Blocks

Lesson Purpose

The purpose of this lesson is for students to compare groups of up to 10 objects in the context of putting together pattern blocks.

Lesson Narrative

In previous lessons, students put together and counted pattern blocks to fill in puzzles. Students have noticed that different combinations of pattern blocks can be used to create the same shape. Students use methods developed in previous units to compare the number of pattern blocks.
