STEM Toys by Age, Chosen for Staying Power

The STEM toys kids keep playing with share a few traits: they're open-ended, they match the child's current skills (not the age printed on the box), and they connect to something the child already loves. These guides are organized by age, with ideas grouped by interest.
Safety first for little ones: the CPSC bans toys with small parts for children under 3, and requires choking-hazard warnings on certain toys with small parts. If younger siblings are around, keep small-part kits out of reach.
