The curve pieces snap on easily enough for my first grader to make cylinders on her own, which was a pleasant surprise. Sticks and connectors stayed put during a wobbly tower attempt, so the 3-D builds actually hold together.

My kids kept grabbing the same handful of sticks during math time, so the two different connector types have been a lifesaver for spreading out the building. The curves are perfect for making cylinders, which is a step up from the flat shapes in our old set. Took about ten minutes to figure out how

The different sized sticks and curve pieces make building everything from basic triangles to cylinders so intuitive. My 2nd grader has been playing for an hour straight, figuring out how to connect the 3-D shapes. It is rare to find a geometry toy that is this engaging for a kid.
