**Use this interactive base-10 block manipulator to represent numbers up through the thousands place.**

Use the Interactive Base-10 Blocks Widget with your class to virtually manipulate place value blocks on your interactive whiteboard or computer. Find totals, represent numbers, and explore place value.

Simply drag the base-10 blocks from the black space at the bottom of the screen and drop them into the work area. Remove a block by dragging it back into the black space. Clear the screen by tapping the red trash can button.

### Live Count

The Interactive Base-10 Blocks Widget adds the values of the blocks and displays the amount on-screen. The live count can help students with addition and remembering the values associated with each type of block. Click the yellow show/hide button to toggle the live count’s visibility.

### Place Value Mats

Work on a virtual place value mat by using the different preset themes. Choose either the Tens, Hundreds, or Thousands theme to provide a scaffold for your students when they are representing numbers. Note: Only relevant blocks will be shown when using themes.

### Randomize Blocks

Use the manipulative’s randomizer function to add a random amount of blocks to the work area. With the live count hidden, have students sort these blocks into the appropriate place value area and determine the total value. They can then click the show count button to see if they are correct. The minimum and maximum values for the randomizer can be altered in the settings menu.
