Add Ten (Expanded Format)

This worksheet presents vertical equations where ten is added to a wide variety of two- and three-digit numbers, using expanded grid alignment for clarity. Students practice organizing digits carefully, reinforcing the concept that adding ten affects only the tens place. The problems progress through numbers in the 20s, 80s, 100s, and beyond, strengthening flexible place-value understanding. Students build computational fluency as they repeatedly adjust the tens digit and determine the resulting sum. The visual structure is especially helpful for learners who benefit from guided organization.
