This lesson explores 2.OA.C.4 - working with rectangular arrays and writing addition equations to show the total in order to gain a foundation for multiplication.  Students work in pairs to create arrays for a given number, and then write number sentences to describe each array.  [Some students work beyond the standard's prescribed 5 rows and 5 columns.]  Core Action 3 is solidly demonstrated in this lesson.
