My kids are really not puzzle kids (DS is a bit more than DD). In this case, I think they're about average for kids of educated parents who are not gifted in this arena. DS was doing 24-piece puzzles at about 2.75, and that's still about right for him. Most 24-piecers say 3 and up, suggesting that 3yos can often do them. So I'd say that if a classroom for kids who are preschool age, meaning between 2 and 5, only has 8-piecers...that would be weird. I would say that by age 5, many bright-average kids of involved and educated adults can do 48-piecers and some can do 100 pieces. DD and her best friend both seemed sort of highish average on this and both were doing 100-piecers at 5. I do think puzzling improves quickly with practice, though.
