Unit 1, Lesson 4# Analyzing situations of equal groups: Part 2

Student Achievement Partners 30 min(s)

Lesson builds on students' work with visual models of equal groups to develop an understanding of the specific structure of the array. Work in this lesson builds on the experience students had in grade 2 with arrays to connect to the understanding of multiplication as equal groups. Arrays are defined as a particular arrangement of equal groups into equal rows and columns. To help students see the connection between equal groups of objects and arrays, arrays should be formatted so that the rows are clearly arranged as groups (see problem #1).
