Two wooden boxes with lids each containing 6 cylinders. The cylinders in one box have red tops and those in the other box have blue tops. The cylinders are sealed and make a distinctive sound when shaken. The sounds are graded from quiet to loud. The child has to find the matching sound from each box. An extension of this activity is for the child to grade the cylinders from loudest to quietest. This activity develops the child’s auditory sense and their ability to concentrate.
