Skills at play
What this kind of play tends to build
- Spatial reasoning
Working out which way round a piece has to go before trying it.
- Sensory processing
Texture, weight and light give the nervous system something to sort.
- Planning and fine motor
Deciding what to make, then getting fingers to agree with the plan.
- Problem solving
A puzzle with a right answer teaches sticking with a wrong one for a while.
This describes what this style of play generally supports, drawn from how kids use it. It is not a promise about any one child, and no toy replaces time with you.
