C15 · Build three equal scene kits
Fictional ordinary teaching source. Keep the worked response with adults/after-own teaching; it is never a preset for a held own response.
C15
Three pretend scene kits each need four whole scene cards. How many scene cards are needed for the three kits together?
Adult worked possibility · after own attempt
There are 3 known kits with 4 scene cards in every kit. Build or draw each kit separately and count every member once. 4+4+4=12 scene cards in all. The numbers 3 and 4 name different quantities, so adding them as two loose parts would not represent the kits. Check each of the 3 kits still contains 4; 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.
