The Equation Maker provides a hands-on approach to learning basic addition and subtraction facts. This is a great product for both visual and tactile learning styles. This comes with interactive, push-button lights on the bottom (runs on one 9 volt battery), and colorful matching wooden beads on the top that can slide from side to side. The middle row has three dry erase boards and a flippable addition/subtraction piece. The base of the Equation Maker is solid wood. Kids won't even realize they are learning when they are interacting with both lights and color! This is even great for kids that are struggling with writing or recognizing their numbers. The possibilities are endless!
