Understanding Division through Arrays

This video tutorial teaches how to find missing quotients in division problems using arrays. It begins with a review of multiplication facts and their representation as arrays, highlighting the inverse relationship between multiplication and division. The tutorial provides an example using 40 diamonds to demonstrate division into groups. It then explains how to use arrays to solve division problems, specifically finding the quotient when dividing 32 by 8. The lesson concludes by reinforcing the concept that arrays can be used to solve any division equation.
