Vertical Ten Addition Answer Key

This worksheet provides structured vertical practice for adding ten to multi-digit numbers using a clear place-value grid. Students align the digits in each box to maintain correct placement of ones and tens, which reinforces strong place-value understanding. The consistent vertical format helps students visualize how adding ten only affects the tens place unless regrouping is needed. Through repeated practice, learners develop fluency and build confidence in adding tens to numbers between 70 and 140. This worksheet effectively supports both foundational addition skills and early multi-digit computation strategies.
