This product is an extremely fun, but simple math game for students of all ages to play. If you're using this product with younger grades (K-3), have students roll dice with dots on them so they can physically count the number of dots on all three dice. If you're using this with older grades (4-5), have them roll dice with actual numbers on them so they are working on number recognition as well as mental math. This game would work very well used as a center, but it would also serve great purpose inside a math tub. This product is a great way to engage students of all ages while working on simple addition of single-digit numbers. This particular roll-and-cover is to be used with three dice. Potential sums range from 3 to 18. Enjoy!
