What Your Child Will Learn
Grade 3 students extend both operations to numbers up to 1,000, using increasingly efficient written methods while continuing to rely on the inverse relationship to verify their work. A major focus this year is developing the judgment to choose the correct operation in multi-step word problems, some of which include extra or irrelevant information that must be filtered out.
Students also apply addition and subtraction together in practical contexts: calculating change from a purchase, finding elapsed time, or determining a missing amount in a measurement problem. Fact fluency to 20 is expected by now, which frees up mental energy for the more demanding task of interpreting a problem and selecting the right combination of operations to solve it.
Skills Covered
- Adding and subtracting numbers to 1,000 with regrouping
- Using addition and subtraction together to check work
- Selecting the correct operation in multi-step word problems
- Filtering out irrelevant information in word problems
- Solving money and elapsed-time problems using both operations
- Finding missing values in addition and subtraction number sentences
Curriculum Aligned: Aligned with Strand B (Number): adding and subtracting whole numbers to 1,000 using a variety of strategies and applying the inverse relationship.
Parent Tip: Give your child a receipt or a bill and ask them to figure out the change, then check it by adding up from the change back to the total. It's real-world practice for both operations at once.

Check my workFrequently Asked Questions
How many addition and subtraction problems should my child practice daily?
10-15 problems per day is a good target. Consistency matters more than volume. Short daily sessions build fluency without causing frustration.
What strategies help with addition and subtraction?
Number bonds, counting on, making ten, and using a number line are effective strategies. Start with manipulatives for younger students, then transition to mental math.
When should my child memorize addition and subtraction facts?
Most curricula expect basic fact fluency (sums to 20) by the end of Grade 2. Focus on understanding first, then build speed through regular practice.
