10 More 10 Less: 5 In a Row!

As your students work on common core standard 1.NBT.C.5 (mentally finding 10 more or 10 less than a two digit number), this fun game will give them a reason to use this skill as they try to capture squares on a game board. As partners draw number cards, they can strategically keep the number they drew or change it by adding or subtracting ten in order to get the number they want! This fun game requires almost no prep and makes a perfect math center!
