Big Ideas: Arrays help organize equal groups for multiplication and division. This lesson builds on students' prior knowledge of multiplication and division being represented by equal groups and representing those equal groups into arrays. In this lesson, students will develop a further 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)
