NCTM’s view of problem solving
1) Problem solving means engaging in a task for which the solution method is not known in advance.
2) Problem solving is an integral part of all mathematics learning, and so it should not be an isolated part of the mathematics program.
3) Choosing worthwhile problems and mathematical tasks
– There are many, many problems that are interesting and fun but that may not lead to the development of the mathematical ideas that are important for a class at a particular time.

Task for each table-Wednesday and Thursday-• Short sketch of teaching through
problem solvinga) Purpose of the problem solving (goal of the
lesson)• What mathematics, beside developing problem
solving skills, you would teach by using this situation?
b) Questioning• How would you pose the problem• What question(s) would you ask to your
students to learn mathematics?c) Beyond show and tell
• Anticipate students’ responses to your questions that including misunderstandings to facilitate discussion
• Briefly describe how would you facilitate discussion
