Participant project
Classroom Activities Project:
In order to stay on pace to complete your project and to receive feedback from your colleagues, we recommend that you complete the following over the course of this unit:
1) Select at least one fair-sharing fractions problem and plan when you will attempt it with your class or a small group of students. You may choose to select a problem from below, to create your own, or to use a task from another resource (either as is or adapted to your purpose).
2) Use the task that you have selected to conduct interviews with several students to examine their thinking and strategies for the problem. For more information on interviews with students, watch examples of interviews with students, [Read transcript here], and/or read a summary about clinical interviews. We recommend that you take notes and write a reflection on what happens during the student interviews.
3) Share your reflection in the discussion forum.
Discussion: Share your progress, ask your questions. Your discussion can include:
The problems you used with your students.
- Strategies your students used to solve each problem, including the understandings, confusions and misconceptions they showed in their work and in your interviews

1) Download and save with a new name the Alternative Project Proposal Form. Complete the form by describing your project's rationale, goals, planned content, and development schedule.
2) Share your proposal in the discussion forum either by pasting the information directly into the text box or uploading it. (We recommend pasting the content, as it allows your colleagues to review the content without downloading your form.)
3) Provide feedback on one or more of your colleagues' project ideas. (Additional Guidance for Providing Feedback)
