I would cut shapes out of construction paper and fill a container for the little ones to “glue” down onto construction paper using glue sticks. I would also gather objects for the kids to trace.
I bought special markers and notebooks, construction paper and supplies, puzzles, flannel graphs, Do-a-Dots, etc.
These items went into a box or special place in the closet and used ONLY during “school time” each day.
I would change their activities often, before they tired of playing with them so the next time we got it out, they had the anticipation of more fun.
We have a large list of suggestions for School time Activities for Preschoolers on our website.
