ABSTRACT
The Japanese approach of TTP uses problem-solving as an integral part of every lesson for every grade. TTP can be used to introduce new knowledge, procedures, and strategies. It can expand students’ understanding by giving them new situations in which to apply their knowledge. It can also reinforce how to think mathematically through open-ended problems with multiple correct solutions. This chapter opens with five units of problem-solving lessons that develop conceptual and procedural understanding to show how you can use problem-solving to teach new material in your daily lessons. It also includes five spotlight lessons which require students to extend their understanding of mathematics, and four spotlight lessons which feature open-ended problems that facilitate students’ ability to think mathematically. The TTP lessons collected in this chapter range from lower elementary to lower secondary grade levels.
