Here are the rules:
1) The app has to have some substance as free. In other words, it can't be a few seconds of play and then require an in-app purchase.
2) My kids or I have to like it.
3) It can't have ads all over it.
Taking all that into consideration, today's Free App of the Day is Motion Math: Hungry Fish! This app does contain in-app purchases to access subtraction and negative numbers, but the addition section is a complete level and free! Also, the in-app purchases are accessed from a menu and not thrust upon you in the middle of play.
From the award-winning creators of Motion Math and Motion Math Zoom comes an intuitive way to visualize addition: as the bringing together of two objects. Most math worksheets and math games ask "3 + 4 = ?" Hungry Fish instead challenges players to find, for example, the many different ways to create a sum of 7.
Practice mental addition with Motion Math: Hungry Fish, a delightful learning game that's fun for children ages four and up (there's even advanced levels to challenge grownups!)
Your fish is hungry for numbers. You can make delicious sums by pinching two numbers together – instant addition! Keep feeding your fish to win a level and unlock new fish colors and fins.
The app is free to try, with in-app purchases for subtraction and negative levels (plus bonus fish colors and fins) available for purchase.
