Little Blue and Little Yellow. I had each child a little ball of yellow playdoh and a little ball of blue playdough. I tell them that they have to keep them separate and cannot let them touch. As we read the story when blue and yellow meet, I tell them to have blue and yellow hug. And hug and hug and hug until they make green. Once the story is done and they are done playing with their doh, I give them a plastic zip sandwich or snack bag. There are 3 different labels included in this set. One you can use as a fold over the the top of the baggie, or the labels on the other pages I have made into stickers with sticker paper and stuck them on the baggie. You could also use plain paper & wide tape, or simply staple it. Your choice. I just like to send it home with some sort of explanation of what their child learned at school that day. Enjoy.
