Reflection: Intervention and Extension Compensating to Compute Smaller Numbers - Section 2: Teacher Demonstration


This sort of guided practice provides a perfect differentiated learning experience for students. While some students needed all the time provided to come up with One Strategy, others were able to represent Mutliple Strategies for each problem on their boards. This also provided me with the time to support and question both struggling students and students in need of enrichment. For some students, I might ask: Can you help me understand this part? Whereas other students I might ask: Can you come up with a new strategy that no one else has shared?
