I love when I discover towers like this in the block area. These lovely blocks are from Community Playthings and are worth every penny. They are strong and super sturdy and can be stoon on, slid down, stacked up, and not. Sometimes the nooks become houses for our dinosaurs, sometimes the children like to pass items to ech other through them. They can also be put together to create a large platform for the children to perform on. So many ways to be played with, the best is how open-ended they are.
