Create crafts to go along with the book. Let children create a scene from the book. Provide blue construction paper to represent the sky and let children cut white paper into the shape of a snowman. Provide gray construction paper and help children cut out mice shapes to add to the scene.
Help children learn to work together as a team, just like Clayton and Desmond do in the book. Provide children with three large plastic foam balls along with other craft materials. Divide children into teams who will have to work together to build a snowman. Each team member takes a turn to assemble part of the snowman. One player will connect the bottom two foam balls with tooth picks and the next player can attach the top ball. Players continue to add pieces until the snowman is finished. This can be turned into a game simply by adding a time limit.
Another craft project is to create puppets to retell the story. Create a snowman puppet out of a white plastic spoon. Make a stocking cap out of felt similar to that featured in the book and glue it to the top of the spoon. Add paper eyes, nose, mouth and a green felt scarf. Create a mouse puppet by cutting a mouse face out of paper and gluing it to a spoon. Have children act out the story with the puppets.
Ask students to create their own story based the characters from the book. Have them continue the story or choose an entirely different theme with the same characters. For instance, ask children to write about Clayton's and Desmond's lives during other times of the year or how their experience in building a snowman together changed their friendship.
Other activities include making masks based on the characters and acting out the story, and reading other books about snowman and comparing them to "The Biggest Snowman Ever."
