1. Welcome to Algebra for All Septemer 25, 2009

2. Today’s Goals Collect data and represent it in a graph. Explore linear situations. Review recursive representation. Create scatter plots using the calculator.

3. Homework Debrief At your site, discuss the implementation of the “Shapes of Algebra” activity. What went well? How did you modify it? How could you extend the activity? Other?

4. Recursion Discussion

5. Marching in Place Roles: Marcher – this person “marches” in place to a four-count Counter – counts out loud the number of “four-count” cycles the marcher completes Timer – using a watch that records seconds the timer announces the time at 10-second intervals, i.e. “10 seconds, 20 seconds” Recorder – writes the number of cycles completed at each 10-second interval

6. Marching in Place Conduct the experiment for 2 minutes recording the number of completed cycles every 10 seconds. Organize data in a table. Make a table and graph of the group’s data to share as a poster presentation.

7. Linear Functions: Stations Activity Graph linear equations and complete a table of values for each equation. Identify the slope and y-intercept of linear equations in slope-intercept form. Explain the effects of “m” and “b”on a linear function in slope-intercept form.

8. Who Will Be the Doctor?

9. Homework #2 – Wait Time Read “Never Say Anything a Kid Can Say” Be aware of your wait times in the next month and report back to the group in October.

10. Wrap Up Collect data and represent it in a graph. Explore linear situations. Review recursive representation. Create a scatter plot using the calculator.

11. Wrap-up Complete the evaluation Thanks for your interest and participation in the AFA project! Have a great day and see you October!
