Unifix cubes are a concrete representation of addition/number bonds. Building the bond with the Unifix cubes is what develops number sense. Great use for flash cards instead of looking for just memorization
Great class activity or game when you have time to spare at end of class.or want to practice vocabulary! Project on the big screen and give them flyswatters, spoons, or use their hands to slap correct image. Can divide into teams and keep score!
