PRODUCT DESCRIPTION

An illustration of how commutativity works. Students circle dots on an array, write the appropriate equations (verbally and numerically), and then rotate the array 90 degrees to illustrate the reversing of “number of rows” and “number in each row.”

You can write in the factor you want students to illustrate and copy the pages for your students.

The row is the group, so the order of multiplication equations is always “number of rows times number of dots in each row.”

The activity opens with a discussion of arrays, and places where students can find and describe examples of arrays in the classroom.
