In these First Grade and Second Grade math worksheets, students practice adding whole tens (or multiple of tens) to 2-digit numbers. There are 2 addends which are not more than 100. Students can use pictures (base ten blocks) to do that, or they can add the tens and keep the ones digit the same. For example, 60 + 23 becomes 6 tens + 2 tens and 3 ones, which is 8 tens and 3 ones. (60 + 23 = 83)
