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.

Ratings and Reviews

Good for place value. . . maybe


My daughter is ready to learn to carry, so I want to reinforce place value first. So far with this app, the blocks are fine, but too much of the work is done for you. When the blocks are placed in the columns, the math problem at the bottom (in the blue boxes) counts them up. It even assumes that the carrying has been applied, even if the 'ones' column has more than 9 cubes. She might get the idea of carrying with this app, as well as borrowing, but we will see how well it converts to actual practice. Also, when the hundred column reaches "10", it does not create a 'thousands' column, which does little to reinforce the idea that each column can only have 0-9. (As I was writing she just showed me that the addition problem at the bottom didn't match the cubes at the top because they did the carrying before she did. She is a bit confused.) I will re-review when she has had a chance to use it for a while. I don't write many reviews, but I tried this app without any input, so I thought I'd put a little something in for the next person.

Use the regrouping buttons to regroup blocks from one column to the other.

Great app for teaching

I hesitated buying this app for my classroom because of the negative reviews given about previous versions, but I really like it and it is easy to use. My students are able to move the blocks around the screen without getting confused about where they are in the chart. I like the fact that they have to tell it to regroup when adding and it doesn't do it automatically which allows them to better see what they are doing and they don't get confused and stop counting. Over all it is a good app I am glad I got it.

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.

The update fixes this problem.
