Subtraction Within 100 Worksheets (No Regrouping)

These worksheets practice two-digit subtraction by place value: subtract the tens from the tens and the ones from the ones. Every problem works without regrouping (borrowing), so each column can be solved on its own.

They go a little beyond the 1st grade standard, which covers subtracting tens, and lead straight into 2nd grade subtraction. They are a good bridge for strong first graders and a good warm-up for second graders.

Sample problems

  1. 60 − 30 = _____
  2. 97 − 32 = _____
  3. 97 − 13 = _____
  4. 79 − 62 = _____
  5. 85 − 41 = _____
  6. 99 − 26 = _____
  7. 98 − 28 = _____
  8. 95 − 10 = _____

Worked example

86 − 13

  1. Subtract the tens: 8 tens − 1 ten = 7 tens, which is 70.
  2. Subtract the ones: 6 − 3 = 3.
  3. Put them together: 70 + 3 = 73.
  4. Check by adding: 73 + 13 = 86. ✓

Common mistakes

  • Forgetting a zero in the answer. 81 − 51 is 30, not 3: there are 3 tens and 0 ones.
  • Subtracting across places, like taking the ones digit from the tens digit. Columns or base-ten blocks keep the places straight.

Tips for practicing at home

  • Use a hundred chart: moving up one row subtracts 10, and moving left one square subtracts 1.
  • Act it out with dimes and pennies.
  • Check every answer by adding it back.
