Cylinder Extensions by Cathie Perolman

The Cylinder Game.

Each child has a box of knobless cylinders. They take their cylinders out
and place them on the lid. Then the child who thought of the games selects a
cylinder and places it in the center of the container. The child to his
right has to find a cylinder that is the same diameter or the same height
and places it in the center as well. That turn proceeds until each child has
had a turn. Then each child puts his used cylinder in the box and the next
child to the right begins the cycle again.

This is a nice way to engage five year olds and it lets you say the words
height and diameter.
