This product can be used for many purposes in your classroom. I use it with exit tickets. My students get to color in one space when they get a 100 on an exit ticket. When they fill in a column, they get a piece of candy. When they fill in the whole challenge, I bring them a Powerade slush from Sonic. It is a great motivator! My kids love to "color an emoji!"
