After researching marine organisms during science, Fourth Graders communicated their new learning by constructing cardboard arcade games. Students completed research collaboratively using various sources during Library and then planned and created interactive cardboard games to teach First Graders about their organism’s adaptations, diet, predators, or ocean zone. First Graders were learning about the characteristics of living things, so the arcade also supported their science unit. Fourth Graders were challenged to think critically and creatively to design and execute a fun, informative, and age-appropriate learning experience for younger students.
