Children's house has been in a knobless cylinders state of mind! This sensorial material is as beautiful as it is fun! There is so much to explore with them. The child is able to notice the differences in the height and diameter of each of the cylinders, depending on which of the four different boxes they have chosen. The favorite way to build them at the moment is vertically! The ultimate satisfaction occurs when placing the smallest cylinder at the top AND having it stay in place. mindsprout.me/hybrid #woodlandsmoms #mindsprout
