I gave Jack our color buckets again. (Target dollar station) and some sponge fish. We stuck to 4 colors this time.
I modeled how to match the color to the box then placed them in the box saying the color.
He did it with a little guidance then quickly lost interest and carried around the boxes to play. He used the fish to dump and refill the boxes. Sometimes he would put them in the coordinating boxes other times he would not. The whole activity lasted about 5 minutes.
