We can do this activity both on tables and on the floor, and it is a great one to do after sports, to calm down and relax.
We give each child an empty jar and a paper. We put a little amount of salt in the middle of the paper, and the child starts colouring it with a coloured chalk. When no white salt is left, the child has to pour it in its jar so a thin layer is formed. The child repeats the action with different colours until the jar it's full.
