It covers fractions, equivalent fractions, common denominators, comparing and ordering fractions, adding and subtracting fractions, multiplying, and finally dividing fractions.

Each topic has four sections so a student can work through the activity at his or her own pace. Each section starts with a lesson, questions to check for understanding, manipulatives for visual/kinesthetic and a challenge with problems of differing difficulty.

In addition, a student can earn badges for their work.

I see this app being used in several different ways. It could be used in the elementary grades as the material is introduced or it could be used in higher grades to reinforce or differentiate instruction. I know I have some very low performing students coming in who will need the instruction and reinforcement.
