### 5/5 — Easy to understand, fun for kids

*2020-04-27*

This is not in English, but very easy to figure out how to use! Lay out the colored blocks according to the numbers given, in the order and color that the numbers indicate. You can tap the “?” symbol if you are unsure how to do it, and the app will demonstrate for you! It is a fun visual-spatial and counting activity. There is a very small and unobtrusive ad bar at the bottom of the app, as an FYI- you can use guided access to cover it up so there won’t be unwanted clicks outside of the app.
