Monkey Math is a big hit in grade one right now. It is fairly simple math, definitely review but the grade ones LOVE it and it is extremely appropriate for my daughter in kindergarten and the special needs student on a modified program in our class.
Monkey Math covers almost all areas of the curriculum. There is a reward tank. You earn fish and items for your tank with each correct answer.
The app is recommended for kids aged 3-6.... well worth the 99 cents!
Another great Monkey app I just discovered is Monkey preschool Lunchbox. It is the same little monkey teaching about letters, numbers, colors, matching, patterns and counting. This app is recommended for kids age 2 -5, but if they love the Monkey Math little monkey then this guy will capture their attention too!
This is our in class exploration tomorrow!
