Wondering how to incorporate science, technology, engineering, and math PLUS collaboration, critical thinking, problem solving, and digital literacy into the PreK-K curriculum? You can do it with project-based learning units and scaffolded activities through which young students design, create and use learning/play centers. The book presents 8 units, each broken down into 5 phases with specific guidelines, options for adjustments, and suggestions for parent support. This "learning by doing" approach is fun, and it allows learning to come naturally as children who are bubbling with different abilities, backgrounds, and ideas work together.
