Planning a Joint Solution 1. Take it in turns to explain how you did the task and how you now think it could be improved. 2. Listen carefully to explanations. – Ask questions if you don’t understand. – Discuss with your partners: • • • What you like/dislike about your partners’ math. How clear their work is. How their work could be improved. 1. Once everyone in the group has explained their solution, plan a joint method that is better than each of the separate solutions. Everyone in the group must agree on the method Projector Resources Solving Quadratic Equations: Cutting Corners P-2

Evaluating Student Sample Responses 1. Take it in turns to work through a students’ solution. – Try to understand the method the student has chosen, and any errors he or she has made. 2. Explain your answer to the rest of the group. 3. Listen carefully to explanations. – Ask questions if you don’t understand. 4. Once everyone is satisfied with the explanations, write the answers to the questions below the students’ solution. − Make sure the student who writes the answers is not the student who explained them.
