I created this worksheet to reinforce fact families with my students, specifically in multiplication and division. I wanted them to see the inverse operation and be able to solve any multiplication or division problem using an array, repeated addition / subtraction or by drawing a picture or "groups of". I began with the the 2 2 4 family and ended with 9 10 90. I mix up the pages so that my students work out the problems rather than building on the day before. You can utilize in any way that fits your students.
