How far do you live from school?
Prior to this activity students determine how far they live from school and how long it takes them to get to school. They analyze this data using various types of graphs and draw conclusions regarding the relationship between time and distance. They also look at zip codes and explore factors that...https://education.ti.com/en/activity/detail/how-far-do-you-live-from-school
Linear Equations, How Can I Tell?
This is a lesson to be used when introducing linear equations. The class is to determine parallel slopes, slope of the line, and slope- intercept form while investigating the graphs.https://education.ti.com/en/activity/detail/linear-equations-how-can-i-tell
Geyser Water Park
This activity deals with the slope-intercept (y=mx+b) formula. It is a good introductory lesson for using the formulas. It also includes setting up a chart and the students have to enter the data into the calculator and graph the results.https://education.ti.com/en/activity/detail/geyser-water-park
Flatland: The TI-Book
One of the best geometry books of all time is Flatland. Written over a century ago, there is no copyright for this book and you can find it available free as a podcast or a text file. However, nothing beats a TI-book with nicely produced diagrams.https://education.ti.com/en/activity/detail/flatland-the-tibook
"Add Them Up" for TI-Nspire
