Math-tastic is a set of apps specifically focused on the needs of kids learning math.
Learning math takes focus and Math-tastic is built from the ground-up to provide a focused framework for reinforcing the fundamentals of math while having some fun.
Math-tastic Subtraction is focused only on teaching subtraction. Starting from single digit subtraction, kids can work their way up through ten levels of subtraction mastery. Math-tastic allows the student to write their own answer on the iPad's touch screen, allowing the student to work through the problem on their own. Once they have written out their answer, they can then enter the answer for instant feedback.
Every answer is saved, so you and your math student can review questions and answers later.
Math-tastic Subtraction also includes six tutorials on subtraction from khanacademy.org, so help focused only on subtraction is just a couple taps away.
