First, call the kids so that they can watch you dump out all of the plastic containers and lids all over the kitchen floor - for some reason it is really fun for kids to watch mom/caregiver making a mess......they will squeal with delight. Next talk with the kiddos about matching - shapes, color, size. Have the children match lids to containers. Hey, may as well make it "educational". Place correct lids on the correct containers and make a tower. I encourage the kiddos to try to make a tower taller then me! Leave containers on the kitchen floor ALL day for two reasons: 1. The kids can come back to play, building more towers throughout the day. This beats any fancy "learning station" found at a daycare/preschool center. 2. By the end of the day I had a grudge against all those containers that I had been stepping over which made it much easier for me to say good bye to my "abundance". Background are the "lid holders" Organizin
