A labeled diagram helps readers identify parts of an icebreaker, while a picture glossary reinforces new vocabulary. Children can learn more about icebreakers online using our safe search engine that provides relevant, age-appropriate websites. Icebreakers also features reading tips for teachers and parents, a table of contents, and index. Icebreakers is part of Jump!'s Machines at Work series.
