Creativity grows through open-ended making — activities with materials and starting points but no fixed destinations. These art activities are chosen for the decisions they leave with the child.
Creativity is a decision-making muscle — and art activities build it exactly to the degree that the decisions stay with the child. The activities below maximise child-decisions per session.
The adult behaviours that grow or kill it
Growers: genuine curiosity ("tell me about this part"), description over evaluation ("so many windows on that flying house!"), and visible adult creativity (drawing badly alongside them, cheerfully). Killers: fixing their work, "what is it?" delivered as skepticism, template-pushing, and praise so generic it teaches nothing. The meta-message that matters: their ideas are worth having.
Boredom's role, again
The pre-creative whine — "I don't know what to make" — is the runway, not the emergency. Materials available plus boredom unrescued equals invention, more reliably than any prompt; the prompt library above is for kindling, not for replacing the fire-starting.
Creativity beyond the art table
The same decision-muscle transfers: pretend-play plots, block-city designs, invented games with cousin-negotiated rules. Art is creativity's most visible gym, not its only one — and the child whose ideas are welcomed at the art table brings ideas everywhere else.
