Subtraction is a tough concept for Kindergartners to learn. I’ve tried to come up with all sorts of games, chants, songs, books…etc. Something that has always stuck is the “minus” mustache. The kids think it’s hilarious, and they are always referring to it during word problems or when they are practicing subtraction after it’s been introduced. I decided to come up with a game called “minus mustache” to help reinforce with more subtraction practice.
