Week 26: Phase 4 Review
Comprehensive review of Phases 3-4: measurement, time, money, data, geometry
Standards: 2.MD.A.1, 2.MD.C.7, 2.MD.C.8, 2.MD.D.10, 2.G.A.1-3

Review week — mixes questions from Weeks 16-24; no new content.

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 (explain WITHOUT calculating)
- Friday self-check with reflection
