1. Subtraction Directionality:
Watch for students doing \(2 - 7 = 5\) instead of regrouping. Have them highlight the top number and ask: "Can I take 7 candies if I only have 2?"
2. Scratchpad Organization:
Ensure students label their scratch work with the coordinate (e.g., 2C). This allows instant spot-checking when students call out a completed row or blackout!
