Lesson 6
Usemos más, menos o el mismo número para describir grupos
Lesson Purpose
The purpose of this lesson is for students to use comparison language to describe the number of objects in groups.
Lesson Narrative

They heard and made sense of comparison statements such as “There are more orange squares than green triangles.” In this lesson, students repeat and produce comparison language to describe the number of objects in groups.
