In these math worksheets, students solve addition problems by drawing and combining rods ("tens") and blocks ("ones"). The last two worksheets require regrouping ones into tens (as there are more than 10 blocks following the summation).
Explore all of our place value worksheets, from base ten blocks to 6 digit numbers in expanded form, and our rounding worksheets, ranging from rounding to the nearest 10 to rounding in the millions.
