Printable Worksheets for adding multiples of 10:
Add 10 to a 2-digit number (eg. 10 + 24)
Add Whole Tens (eg. 50 + 60)
Add Tens to a 2-digit number (eg. 60 + 34)

In these First Grade math worksheets, students practice adding whole tens (or multiple of tens). The 2 addends are not more than 100.

Students can use pictures (base ten blocks) to do that, or they work with the number of tens the same way as adding single-digit numbers. For example, 60 + 20 becomes 6 tens + 2 tens, which is 8 tens. (60 + 20 = 80).

Key points:

• Recognize that you’ll only be adding in the tens place.
• The ones place remains as 0 because multiples of 10 have a 0 in the ones place.
