Big Ideas: Arrays are formed with rows and columns. Multiplication and division are inverse operations. This lesson builds on students' prior knowledge of multiplication and division being represented by equal groups. In this lesson, students will develop an understanding of organizing equal groups into arrays through multiplication and division. Students will examine ways in which they can partition a number into different arrays. By the end of this lesson, students should have a conceptual understanding of how to organize equal groups into an array and how multiplication and division can be shown through arrays. Vocabulary: Multiplication, Division, Array, Row, Column, Inverse Operation Special Materials: Counters (optional)
