These addition worksheets are used with ones and base ten blocks, counters, small erasers, stacking cubes, etc. The students can either complete this on their own or take turns with a partner. They simply stack up the correct number of objects to answer the math problem on top of their square to create a "tower". I print these out on colored card-stock to make it a little more fun :)
