Dr. Looper has gone mad! He has turned all of the people of Tubesville into frogs. Students must reach the lily pond before the doctor in order to save the inhabitants of the town. Easy right? Not so fast. Dr. Loops has scattered looping tubes all over the gameboard to send kids back to where they started! This Smarten Up game will provide kids with support as they learn mental math strategies and develop computational fluency with subtraction.
