Subtracting by Place Value: 3-Digit Numbers

Master multi-digit subtraction with this informative third-grade math worksheet! First, an introduction will show students a three-step process for solving subtraction problems by decomposing numbers. Learners will break each number into hundreds, tens, and ones, then solve for each place value separately before adding the results. Then, students will be asked to use this strategy to solve four problems that do not require regrouping. 

This worksheet is perfect for students who are moving from two-digit to three-digit addition. The decomposition strategy may be familiar to them already, but it can be tricky to balance all three place values: hundreds, tens, and ones. This worksheet gives students practice with this strategy so they can get comfortable using it for larger numbers.
