This exercise has to be done with two people, both Directress and child or two children, either at the table or on the floor. (Note: work cycle to be observed)
The child closes his eyes to focus his attention on the weight rather than the color of the wooden tablets.When he opens his eyes, the child can check whether or not he has sorted the tablets correctly by weight by looking at the different colors of these three types of timber.
Once two or more children have been shown how to do the exercises, two children may work together.Eventually three sets can be used and sorted into lightest, heavier and heaviest.
