Week 13: 3-Digit Addition & Subtraction — REWRITTEN
Phase 2: Addition & Subtraction to 100
Key skills: Hundreds place, regrouping across hundreds, working to 1,000
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
- Mental math ±10, ±100 woven throughout
- Unknowns in equations
- Word problems every day
