Place a mat on the working space. Select the yellow box first. Show the child how to carry the box using two hands cupped around the box. Remove the cylinders one by one grasping them over the top with your dominant hand. Place the box neatly to the side and the top of the mat.
Show the child how to grade the cylinders from biggest to smallest in a horizontal line.
The child grades the cylinders.
Show the child how to build a tower with the cylinders starting with the largest cylinders first. If the mat has a thick, uneven pile, you may use the lid of the box as a base.
The child builds the tower.
The child uses the four sets of cylinders together to discover different properties such as similarities and differences in dimensions between the cylinders.
