In this follow-up app to Addimals, students use subtraction strategies to help Memo, Patooey, and her cousin, Slurp stop his latest evil plan. Subtractimals EDU is the school version of an engaging game that teaches subtraction. The characters once again model strategies that children use to practice solving subtraction problems.
