Assume that you need to report back to your grade-level team or to the entire school staff at a faculty meeting on your experiences and learning in this course. What are the main messages about the teaching of number and operations that you would share with your colleagues? Prepare a one-page handout or an overhead or slide that could be distributed or shown at the meeting.
Look at a lesson or activity in your own mathematics program for your grade level that you think has potential for developing students' reasoning about number and operations. If you were to use this lesson or activity now, after taking this course, how might you modify or extend it to bring out more of the important ideas about number and operations?
