C16 · A set of route kits
Fictional ordinary teaching source. Keep the worked response with adults/after-own teaching; it is never a preset for a held own response.

Four pretend route kits each need three whole route cards. How many route cards are needed in all?
Adult worked possibility · after own attempt
There are 4 known kits with 3 route cards in every kit. Build or draw each kit separately and count every member once. 3+3+3+3=12 route cards in all. The numbers 4 and 3 name different quantities, so adding them as two loose parts would not represent the kits. Check each of the 4 kits still contains 3; then recount or use another taught equal-group method. A multiplication symbol is optional adult shorthand, not a prerequisite or a demand for times-table recall.
