Tell them to close their eyes. While you remove one of the objects let them open their eyes and see if they can tell which object is missing. Let the children take turns playing the game. Increase the number of objects. Remove more than one object from the group while the child is blindfolded.
Place objects in random order instead of in a straight line.
Add an object to the group instead of taking one away. Let the child see the object. Blindfold the child and let him try to identify the missing object by feeling the remaining objects. Examples of objects are measuring spoons, candy eggs, sea shells, play turtle. The pupils are to guess what's in the bag by touching and feeling each bag.
