The trial version of this app is FREE for the iPhone/iPad. Designed for kids ages 4+, this app has 18 different levels. Later levels require knowledge of regrouping so it is suitable for preschool through grades 3 or 4. It fits the Common Core Standards for addition through grade 2. The concept is simple but engaging – kids need to feed the fish in order to keep it alive. The faster it is fed, the bigger it grows.  If it is not fed fast enough it gets smaller and smaller until it disappears. Each fish has a number on its body. It only eats that number. Kids pinch numbers together to create the sum their fish needs. Bonus fish colors and fins become available when a level is successfully completed. Additional levels of addition, subtraction, and negative numbers are available as in-app purchases.

Common Core Standards met in this trial version:

• 1.OA.6 – Add and subtract within 20
• 2.OA.1 -Use addition and subtraction within 100

This is a fun app – I found myself playing it a little longer than necessary to review it 😉

Highly recommended!
