Addition: The Make Tens Strategy
By Cindy Aossey (KCM) & Funda Gonulates (NKU)
Understanding how numbers can be adjusted while keeping the sum the same helps students develop
flexible strategies for addition. In this video, we demonstrate the Make Tens
strategy using
addition problems with two-digit and three-digit whole numbers, decimals, and fractions. By
adjusting both addends in the problem, taking from one and giving to the other, students can
transform a more complex addition problem into one that is easier to solve mentally.
