2-Digit Addition with Regrouping (Every Problem) — Easy Worksheet 1
Grade 2 · MathSheets Name: ____________________ Date: __________
Every problem needs regrouping. The same kind of sum comes in different shapes.
How to solve
Add the ones first. For 38 + 27: 8 + 7 = 15 ones. That is 1 ten and 5 ones, so write 5 and carry the 1 ten. Then add the tens: 3 + 2 + 1 = 6. So 38 + 27 = 65.
