1. Walking to Teach Middle School Mathematics Lisa M Suarez-Caraballo and Bill Stiggers LisaS@copper.net and Bill@apk.net http://education.ti.com

2. Agenda CBR Introduction Your Name’s the Game Walk the Line using the TI-Navigator Topics in Algebra 1 APP – Chapter 3 Assessment and analysis using the TI- Navigator

3. Using the CBR

5. Your Name’s the Game! : Using the CBL/CBR APP and moving with or in front of the CBR try to “draw” the first letter of your first name on the screen.

6. Run the CBL/CBR APP

7. Choose SET DEFAULTS to run CBR and follow on screen directions Select Ranger

8. To try again, select 3: Repeat Sample from the Plot Menu Press Enter to begin collecting data and make a graph

9. Walk the Line Create constant –speed motion plots Today we will have one person walk a line and then we will share that line using the TI-Navigator

10. Walk the Line Once you have the data in Lists 1 and 2 run the SETDEFLT program by pressing  to see the line we created with the CBR

11. Walk the Line Develop Linear Equations to describe the plot we created mathematically. Slope-intercept form of a linear equation is Y=MX+B Guess and Check TRACE and use : slope = (y2-y1)/(x2/x1) Linear regression

12. Other Activities you can do Match a graph to a story or vice versa Feeling Rates of Change

13. Topics in Algebra 1 Overview : 4 (5) chapters 1Number Sense 2Linear Equations 3Linear Functions 4Linear Ineq: 1 Variable 5Linear Systems

14. Topics in Algebra 1 Chapter 3 Linear Functions: Slope with Grid Activities Screen Cross Linked Calculators Screen Cross Drawing Line Segments

15. Soft Keys

16. Use Arrows on Keypad to Navigate
