Unit 4, Lesson 9
Show Me Your Number
Grade 1
Preparation
Lesson Narrative
In previous lessons, students interpreted different ways to represent a two-digit number as some tens and some ones. In this lesson, students create a collection with connecting cubes to represent a two-digit number. Students use what they have learned in previous lessons to represent the collection in as many ways as they can. Students participate in a Gallery Walk in which they observe other collections, represent the collections in as many ways as they can, and compare their representations with their partner.
