Times tables colour by code — butterfly

Each of the six answers (6, 8, 10, 12, 15, 20) can come from more than one fact family — 12 is 3×4 or 4×3, for instance — so the sheet varies which pair it asks for each time it is generated, rather than drilling the exact same six facts on every print.

This is the only sheet in the set built on recall rather than a strategy, which is deliberate: by the time times tables are being practised, the goal is instant retrieval, and the self-checking picture makes hesitation and guessing equally visible in the finished reveal.
