The child inserts the disc through the slot, where it appears to disappear behind the divider board. You or another child has the possibility of joining in with this material. Sit opposite your child and pass the disc back and forth. I think this material would be a nice one for siblings and I look forward to when my son is old enough to be able to use this with his older sister.
This material is nicely made with a felt type green mat in the box.
This Imbucare Board with Disc exercise helps the child improve hand-eye coordination and is another exercise to refine wrist movements.
