Choosing the right operation
By third grade, word problems use bigger numbers (up to 1,000), so the focus shifts to choosing the right operation. Combining amounts means add; finding how many are left or how many more means subtract.
How to use it
Have students underline the question and decide the operation before computing. Builds toward two-step word problems.
👩🏫 Teacher note
Have students underline the question and circle the numbers, then decide: are we combining (add) or finding a difference / what's left (subtract)?
🏠 Parent note
Ask 'Are we putting amounts together or finding how many more / how many are left?'
Common Mistakes to Watch For
- Choosing the wrong operation
- Forgetting to regroup
Answer Key
