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
Using the CBR
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.
Run the CBL/CBR APP
Choose SET DEFAULTS to run CBR and
follow on screen
directions
Select Ranger
• To try again, select 3: Repeat Sample from the Plot Menu
• Press Enter to begin collecting data and make a graph
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
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
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
Other Activities you can do
• Match a graph to a story or vice versa
• Feeling Rates of Change
Topics in Algebra 1
• Overview : 4 (5) chapters
•1 Number Sense•2 Linear Equations•3 Linear Functions•4 Linear Ineq: 1 Variable
•5 Linear Systems
Topics in Algebra 1
• Chapter 3 Linear Functions: •Slope with Grid
• Activities•Screen Cross•Linked Calculators Screen Cross•Drawing Line Segments
Soft Keys
Use Arrows on Keypad to Navigate
TI-Navigator
• TI-Navigator™ is a wireless classroom network that enhances communication between the teacher’s classroom computer and the TI graphing handhelds used by students.
TI-Navigator
