Week 31: Final Review — REWRITTEN
Phase: Final Review (the last SERIOUS review week — Week 32 is the celebration)
Standards: All 2nd grade domains reviewed — 2.OA (add/subtract, odd/even, arrays),
2.NBT (place value, 3-digit +/−), 2.MD (length, time, money), 2.G (shapes, partitions)
New Standard:
- Reduced drill (40% fewer problems)
- Estimation before calculating
- Multiple strategies encouraged
- Better word problems (reasoning over keywords)
- Real challenges (open-ended thinking)
- Number talks (compare without calculating)
- Friday self-check with reflection
- Fact fluency warmup daily
- Word problems every day
