![]() If you were like me, you may never have used base ten blocks and you aren’t quite sure how to subtract using them. The player with the most base ten blocks at the finish wins. If you land on the treasure chest, you get to add 1,000 blocks back to your shrinking pile. Of course, there is a small twist to the game. The players take turns doing this until someone runs out of base ten blocks or both players reach the end.It is now player two’s turn, and they do the same thing.They then write an equation showing what they did on the record sheet. Based on the number they landed on, they take that many base ten blocks away. To begin, player one rolls the die and moves that many spaces. ![]() To set up, both players collect 1,000 base ten blocks and place their game piece at ‘start.’ If you have enough large cubes for each player that is ideal.The object of the game is to be the one with the most ‘treasure’ ( aka base ten blocks) at the end of the game. 3-Digit Subtraction With Regrouping Game: You are ready for your children to play and develop number sense. Finally, print off a record sheet for each player and provide pencils.Next, gather up base ten blocks, a die, and game markers.First, print off the game boards on card stock paper.An understanding that will help them accomplish higher math or even mental math.Īnd that is what this subtraction game is all about: practicing 3-digit subtraction with regrouping in a way that builds understanding and is FUN! When children can draw, manipulate an object, or show how a problem is solved, a deeper understanding is developed. So what does that mean? It means that manipulatives, models, and number lines are used consistently…even with my upper elementary children. I never want to teach another child and leave them in the same place I was for so many years. Subtraction with Regrouping Using Manipulatives This is a guest post from Rachel of You’ve Got This Math. * Please Note: This post contains affiliate links which support the work of this site. I could cross numbers out and carry numbers all day, but it wasn’t until I sat down with blocks that I truly understood why I was doing all that. You see, I knew how to subtract with regrouping. And I was a little nervous about teaching math. But as I played with those base ten blocks that day a foundation would be laid that would change everything. ![]() The instructor proceeded to inform us how to teach subtraction with regrouping using base ten blocks. Though he was there to teach me how to teach a concept, he actually brought an understanding that hadn’t happened in years of schooling. I was sitting in a college teaching class, and the base ten blocks came out. Even though we call these “Base Ten Cards”, first-grade students see them as “Snap Cube Cards”.It was the turning point for me.The key is to not move students too quickly to base ten blocks because it can really undermine the development of unitizing. ![]()
