People have engaged in playing games and solving puzzles for thousands of years. Games and puzzles continue to provide important opportunities for children to experience playful learning. The teacher reviewed the directions of the game and assigned teams. There are five fully developed games or puzzles within each chapter as well as a section that suggests online games and puzzles that are appropriate for the classroom. The online section is less detailed, as such resources change frequently. The “Variations” section suggests ways to change the game or puzzle to better reach the range of learners in your class, to sustain its worthiness as student learning progresses, or to adapt it to better fit another grade level than that indicated in the classroom vignette. Recording sheets and exit questions allow students to share their strategies and knowledge, and provide teachers with the opportunity to assess learning.
