Review Excerpt: Designed specifically to help a young child conceptualize single digit addition (typically when aged 5 to 7 years), this app manages to pull off the nearly impossible — making addition meaningful, by keeping things challenging (and interesting) while providing enough support so that children feel successful. Children will practice addition facts using visual models of addition strategies during the “tool around”. The “speed round” is designed to encourage memorization and provides hints as needed. There is a progress monitoring chart that allows children and parents or teachers to keep track of performance over time.
