The knobs are the perfect size for little hands to grip, and my daughter spent a solid twenty minutes tracing each triangle before fitting them back in. I've noticed her hand-eye coordination getting sharper just from doing it over and over.

The knob on each triangle is the perfect size for little fingers to pinch, and my daughter will sit and trace the shapes for a solid ten minutes. Watching her hand-eye coordination improve while she matches the sizes has been genuinely rewarding.

My 3-year-old figured out the size order on her own after a few tries, and now she traces each triangle with her finger before dropping it back in. The knobs make it easy for her to grip, and it keeps her busy while I cook.
