Operations
- Add and subtract to 1000 using regrouping and mental strategies.
- Build multiplication and division facts up to 10 × 10, starting with 2, 5, and 10.
- See multiplication and division as inverse operations: 3 × 4 = 12, so 12 ÷ 4 = 3.
- Solve one- and two-step word problems and check with estimation.
Learning facts as families (3 × 4, 4 × 3, 12 ÷ 3, 12 ÷ 4) means you learn four facts at once.
