Using The Interactive Place Value Chart

Instructions

Tap the screen to create tokens. You will see the number of tokens displayed atop the place value field.

Move tokens from field to field by dragging. Moving from a lower place to a higher place is only possible if you have enough tokens, that is at least 10 for moving from the ones to the tens or the tens to the hundreds, and at least 100 when moving a "one-token" to the hundreds.

Moving tokens from a higher place to a lower place is always possible. If you move one token one field to the right, you will get ten tokens there.

Remove all tokens by shaking the iPad or iPhone. Remove single tokens by moving them to the top.
