Pom Pom Colour Matching

My son loves pom poms and requests them all the time. Today I decided to put these cute little containers in the muffin tray (for support or they topple over due to the lids) and have my son sort the pom poms into the correctly coloured container.

Once he had correctly sorted all the colours into the containers, he closed all the lids.

I though he was finished, but he decided to stack them all up.

Lastly, he opened all the containers and shook them until the pom poms were back in the bowl.

He spent so much more time at this activity that I had originally thought he would.
