This shortens the waiting time for the toddlers. They do not have to stand in a straight line. I sing continuously in the classroom. This is a powerful way to get the children to focus on what they are doing and helps them to wait for a turn. Try creating activities in the classroom that educate the child's movement.
Toddlers love to transfer things from one place to the other.
Jan Lee is an excellent teacher and contributor on this message board. The children love to carry the basins to a work table and use whatever activity is inside. Anything from bottle washing to feeding the hungry fish. Once the toddler feeds the fish he turns the big fish over and pours the smaller fish into the basin. Toddlers will repeat this exercise regularly.
