Think about the student work and reflect on the following questions:
- What strategies did the students use to find the solution?
- If students haven't completely solved the problem, how can you encourage them to look for additional solutions? What other questions might you ask that focus on the solution process and not just the solution?
- What materials might be available to help students get started? When and how might you use these materials (at the beginning of the lesson, later)? Why?
