So, what have you done in this session?

• In Part A, you observed the use of representations, as young students made estimates and counted a number of objects.
• In Part B, you reflected on your own use of representations as you explored how the area of a geometric figure changes when you change its dimensions.
• In Part C, you saw different ways for students to represent their thinking, moving from their own non-traditional methods to more conventional forms of representation.
• In Part D, you applied the use of representation as you solved a problem involving sampling, and watched how first- and second-graders represented their thinking in a similar problem.
• In Part E, you just made a lesson plan of your own as a way to demonstrate what you've learned.

Now you have an opportunity to reflect on this session and to communicate some of your thoughts and observations in your journal. This final journal entry will mark your completion of the session.
