The unit circle clock is an excellent learning tool for math learners because they can clearly visualize the relationship between the angles of the circle and different units of time. For example, when the hands of the clock are pointing exactly at 12 o'clock, the angle of the circle is perfectly vertical, indicating that it is midnight. Similarly, each of the other times corresponds with different angles around the circle, providing a visual representation of the mathematical concept of angles. Additionally, math learners can learn how to use angles to calculate time more accurately with this visual representation.

but that's not saying much - if you've read my reviews of the other mathy clocks on amazon, I have had problems with all of them EXCEPT this one. Much better quality - runs well, no problems.

This is neat and my nerdy son loves it. It does not seem like a high quality piece. The clock face is simply a thin sheet of plastic with the clock mechanism attached. If it's hung on the wall and left alone, it looks nice and serves its purpose, just feels a bit cheap and flimsy.

Love this variation of clock. Puts time in a different perspective.

Good quality but very cheap materials

Put it some place where it won't move. Hands are very, very fragile!!!

My son is obsessed with everything math and he loves this clock. It’s pretty cheaply made but should last a while since you just hang it in the wall and don’t handle it too much.

My 11 year old really likes this clock. I like it too but it is a bit delicate and easily breakable. I wish it was sturdier.
