This is a growing collection of videos that shows how 1 problem can be worked out in many ways using various math tools and math models. For example, 3 x 26 can be worked out using base-ten blocks or place value discs or using equal groups or using an open array to name a few ways. This growing collecting begins a discussion about the various ways the we can resolve problems, while naming the tools, models, and strategies used.
