Shaving Cream Painting is a process art activity for preschoolers and toddlers. (My 7 year old loves it too.) You need minimal supplies and I guarantee that your 4 or 5 year old child will have at least 30 minutes of sensory fun.
Toddler threading activity with giant cardboard beads. Could be a little project to have them paint the tubes, let them dry, and cut the tubes into smaller lengths (with some help). Add stickers for decoration and even more fine motor practice!
