Product Description
This is an activity I tried out on my second graders and it was dope: the idea is that while students know "how" to subtract, they don't know all the cool properties of subtraction that make it unique and distinct from addition. In this activity, there are 30 different subtraction challenges that are open ended Here's what you do; introduce the lesson, get the kids going and then watch the magic happen!

Here's the thing; the subtraction challenges are designed so that there some of them will yield an infinite number of solutions, while others will yield a very small number of solutions. And here's what kids will learn: subtraction is more than just the "opposite" of addition - it is an operation that is very different from addition, and that these properties mean that you can do really cool things, like solve the problem 8,000 - 4,923 without the need for regrouping across zeroes.... do this activity and your kids will learn how to do this.....
