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
