Students use this action-consequence document to observe the changes in the slope of a line as the line is moved around a coordinate plane. Initially, students only observe the positive, negative, undefined and zero aspect of slope and describe the graph on a window pane. Further into the investigation, they are using rise over run to find the numerical value of the slope.
Before the Activity
Students will need to know how to connect - to - class to download the document and how to grab and drag a point. They will also need to be familiar with moving through the pages of a document on the nSpire.
During the Activity
The smart board document that accompanies this activity can be found at returner.yolasite.com under the TI-nSpire tab.
