This Problem-Based Learning Activity is meant to serve as an introductory unit for launching problem- and project-based learning in the elementary classroom. Students learn to work in collaborative, problem-solving groups to solve a cookie mystery! This unit asks teachers to prepare two separate batches of cookies so that students can use text-based, inference-based, and peer determined deductions as to what caused the difference in the batches.
Student resources are differentiated by Lexile level. Includes QR links to read-aloud stories.
Aligned to CCSS, this unit is the perfect introduction to PBL for elementary students.
