Bộ Phân Loại Hình Dạng, Xếp Chồng và Câu Đố Hình Học Trẻ Em

The three-in-one thing is what sold me — my two-year-old stacks the rings for a while, then flips to the shape sorter, so it actually holds his attention longer than most toys. The geometric puzzle side is a bit advanced for him yet, but he'll grow into it.

My 18-month-old figured out the geometric puzzle side before the stacking part, which surprised me. The pieces are chunky enough for her small hands, and I like that one toy covers shapes and early math instead of cluttering the playroom.

The shape sorter kept my 2-year-old busy for a solid 20 minutes, which never happens. I like that it works as a stacker and a puzzle too, so it grows with him instead of getting boring after a week.
