Super fine motor, so easy and simple too!!
My twins love to play with hexbug nano's, they use them in their car table, on the light table, on the overhead projector with magna tiles, and just about with anything!
The tubes they come in happen to have a removable lid that has a slot in the top. I removed all of the labeling and realized soon enough that our transparent counters fit into them very nicely!! This makes such a GREAT fine motor activity!! They enjoy it too!
