It was really simple and well explained in the instructions.
My boys loved it!!
We talked about reflection symmetry, rotational symmetry, and different symmetry combinations I'm not sure if Elijah got it, but Adan sure did.
I love watching the tube is rotate, the tumble with all the coloured objects in the viewer great colours and patterns. It was a great learning experience!
Did I mention it was fun??
I know you want one too. You can by a kit or one already put together on Kathryn's other shop:
