Teacher Review

This free app works very much like Place Value Chart but has a nicer aesthetic. It is an app for demonstrating to children rather than independent learning. It is simple to use as you just tap the columns to add counters to them. When a column has greater than 9 counters, you can select and drag 10 of them into the column to their left where they merge to show visually how place value works.
