Two people sit at at table. Both have bags full of matching solid objects.
One person pulls out an object and shows it to the other person. That person then has to reach in their bag and pull out the matching object. NO PEEKING!
It can take a while to feel for the object but they usually find it without assistance.
The children love to play this game with a friend.
You can do this at home with matching objects, even using items such as: spoons, erasers, keys etc... Just make sure the items match in each bag and the child cannot see through the bags. This activity is for the hands only.
