Park City Mathematics Institute Secondary School Teacher Program Reflection on Practice Class: Day 13 Akihiko Takahashi

Aki showed us a chapter of a Japanese 5th grade textbook which he and a colleague are translating into English. This three-week chapter dealt with the development of the area formulas for quadrilaterals and triangles. As he showed us the pages, he pointed out the frequent use of open-ended questions.
