About this worksheet

Subtraction within one hundred is often harder than addition because students must keep track of what is removed and what remains. Regrouping makes the task even more demanding: a child may know they need more ones but forget that borrowing from the tens changes the tens digit. This worksheet keeps all numbers within one hundred while asking subtraction in several ways. Students solve direct equations, word problems, number-line questions, part-whole models, and missing-addend forms. Seeing the same relationship from different angles helps children understand subtraction as a relationship between a whole and two parts, not just as counting backward. Watch for answers that are one too high or one too low after crossing a ten. A quick addition check can confirm the difference.

What your child will learn

  • Subtract within 100
  • Use part-whole models to find a missing part
  • Connect subtraction to missing-addend thinking
  • Solve take-away word problems

Worked example

For 72 - 38, trade one ten for ten ones. Then 12 - 8 = 4 and 6 tens - 3 tens = 3 tens, so the answer is 34.

Common mistake

Forgetting that regrouping changes the tens digit before subtracting the tens.

Helpful hint

Ask which number is the whole and which part is being removed.
