We will use activity center to have student input equations with correct slope and y-intercept.
Before the Activity
If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.
You need to set up the TI Navigator for your class.
Open Activity Center and get the activity ready.
Select contribute: equations and configure: 1 equation, let students view graphs of equations, Let students resubmit equations, and equations from calculator. Then press OK.
The last thing you need to remember to do is EDIT window setting to -10 to 10 for the x and y axis.
During the Activity
During the activity you are going to ask students to enter equations with specific slopes, y-intercepts, or both together.
Check the students graphs for accuracy and point out students errors.
Continue until class demonstrates success with the correct placement of slope and y-intercept.
After the Activity
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
