Great Learning Tool! My kids love this game. I have 7 year old twins and one of them struggles in math. She had been playing this game daily for a couple weeks now and is so pleased with herself at how much better and faster she is becoming in addition. I would love to see a multiplication app from K12!

Won't work with new Android OS/Lollipop I love this game for my son and hope the developers work out the compatibility for Lollipop. My son lost all his points and rewards. Cannot even install the game anew.
