Hands-On Math: Base Ten Blocks is a virtual math manipulative playground where students explore and discover place value concepts and also learn addition and subtraction with regrouping. Our Base Ten Blocks allow students to experience and develop math concepts through interaction and discovery.

When first learning place value, blocks can be set to represent ones, tens and hundreds. Later, to introduce decimals, blocks can be set to ones, tenths and hundredths.

I purchased 3 apps from this site but there is no sound. What can I do to access the sounds? I already adjusted it on the information menu but still no sound.

Turn on the sound by sliding the button on the side of the iPad.

No support for decimals

I've tried and tried again to change the settings so that this app will display decimals (blue for tenths, green for hundredths) and it does not change. When picking "Flats, Longs & Units" in the "Column Headings" setting, the "Decimal Places" setting disappears, instead of greying out. It took me forever to find this setting because it was gone when I had "Flats Longs & Units" selected. It wasn't until I decided to randomly select a different column heading that I saw the setting for decimal places (which, by the way, is useless since it does not work). Also, the settings for "Column Headings" and "Decimal Places" should not be sliders; they should be drop-down lists.

Developer Response ,

The update fixes this problem.

No Hundredths

This is a great app EXCEPT the option to have two decimals does not work. I can get tenths but no hundredths

Developer Response ,

Try the update. This problem has been fixed.
