A week, roughly
How the switch can go
An illustration, not a real family.
Monday. The 7s worksheet comes home. Your nine-year-old knows 7 × 2 and 7 × 5 cold, and freezes on 7 × 8.
Tuesday. No sheet. You draw 7 rows of 8 dots and a line under row 5. "What's above the line?" Forty. "Below?" Sixteen. A pause, then "fifty-six."
Thursday. Five minutes of mixed facts, scored as correct answers only. Eleven. Friday: twelve. Nobody else sees the number.
Next Monday. 7 × 8 comes back in the mix and gets answered without the dots.
