Buis Sorteerblokken

My three-year-old has been obsessed with fitting the square tubes inside the round ones, and it's been perfect for teaching him size order without any screens. The wooden pieces are smooth and chunky enough for his little hands, and he'll quietly sort them by color for a solid fifteen minutes.

The square tubes slide into the circular ones with a satisfying click, and my kid caught on to size ordering faster than I expected. Would’ve liked a sturdier storage box, but the pieces themselves have held up well through daily dumping and sorting.
