Prodigy is our go-to mastery- based tool to give kids lots of fun, engaging math problems while ensuring they are staying up to speed with school standards. The basic version of Prodigy is free, but parents can purchase the premium version which allows them to have more insights into what skills their children are working on. If children do not have specific homework, we recommend they bring Prodigy to work on when they come to Modulo. When the app asks to put in your class code, put in one of our codes to play with friends from Modulo.
