AddThree
© 2017 NumberShapes
This is a math practice and drill experience tool specifically designed to help children add three digit numbers using the “crossing ten” and “regrouping" method. After a confusing tutorial screen you are given the option to take a timed drill (1, 3 or 5 minutes) or play in "I Just Want to Learn" mode with no time limit. The design is confusing, in part because it is not clear how to move to the next problem. Help is limited to hints. Our recommendation is to use with caution and supervision. You don't want to confuse children for the wrong reasons when it comes to math drill. NumberShapes apps are designed for teachers to be used in instructional settings.
