What should Mr. Peters do next if many students are not grasping the math concept?

Going through the first two problems of the practice set together with the whole class serves as a valuable instructional strategy when many students are struggling with a math concept. This approach allows the teacher to model problem-solving techniques, clarify misconceptions, and demonstrate thought processes in real-time. By engaging the entire class, Mr. Peters can observe where students might be having difficulty and provide immediate feedback, which can enhance collective understanding.

This method also creates a shared learning experience, allowing students to ask questions and participate actively in the problem-solving process. By addressing the concept as a group, Mr. Peters can ensure that all students have a foundational understanding before they attempt to solve more complex problems on their own.

Observing how students process the problems during this guided practice can also provide Mr. Peters with insights into the specific areas of difficulty, enabling him to tailor future instruction accordingly.
