About this worksheet

Subtraction within one thousand asks students to reason about what is left, what is missing, or how much more one quantity has than another. Third graders often know the basic facts but lose track of regrouping when hundreds, tens, and ones all interact. This worksheet keeps subtraction tied to place value and meaning. Students solve exact differences, match equations, interpret take-away and comparison situations, use part-whole models, and check whether an answer is reasonable. Support versions use easier values with fewer regrouping demands. Standard and challenge versions include larger numbers and distractors based on common subtraction slips. Encourage your child to compare the answer with the starting number; a difference should make sense for the story and the size of the numbers.

What your child will learn

  • Subtract numbers within one thousand
  • Use place value to separate hundreds, tens, and ones
  • Interpret comparison problems
  • Check differences with estimation

Worked example

Common mistake
