FREE for a limited time – Kindergarten Subtraction. This educational app uses 8 different visual learning activities help kids understand the process of subtracting numbers 0-10. To start, create a profile for each child. Pictures can be added from your camera roll – making it easy for kids to find their files. The app narrates (in English or Spanish) and visually demonstrates how to use the interactive elements of each activity. Then the app uses those 8 different activities to give kids LOTS of practice subtracting. The app provides progress screens for parents or teachers to see how their kids are doing – a great feature. The app is organized so that kids go through the activities in a specific order. If kids already know subtraction -1 they still have to go through all of those activities before they get to subtraction -2. Perhaps an update could make the app a bit more customizable. That being said, the app shows kids how subtraction works in a variety of ways!
