To use Base Ten Block Addition, click the "Next Problem" button to complete an addition problem. Starting with the "1's" column and working your way over to the "1000's" column, look for blocks that can be grouped to form a larger base ten block unit. To group blocks to create a larger unit, click and hold down the mouse while dragging a rectangle to lasso the blocks. When you have selected the correct number of blocks, the blocks will join together to create the larger unit block. Drag the newly grouped unit into the column to the left. The addition solution will appear in the area on the left.
