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
Mystery Point!
Students will discover the nature of the 'Mystery Point' in a triangle. The Mystery Point is a triangle center, constructed through algebraic and vector means, so students can not "un-hide" the construction to discover the center. The students will have to test various center constructions to dis...https://education.ti.com/en/activity/detail/mystery-point
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
Investigation of Similar Rectangles
This activity shows how the ratios of perimeters and the ratios of areas of similar rectangles compare to the similarity ratios.https://education.ti.com/en/activity/detail/investigation-of-similar-rectangles
Finding the Minimal Path to Put Out a Fire
A camper (at position A) must quickly put out a campfire (at position B). The river is represented by the horizontal line segment CD passing through point P. Where should point P be positioned on the river so that the camper will travel the shortest (minimal) path from point A, to the river at po...https://education.ti.com/en/activity/detail/finding-the-minimal-path-to-put-out-a-fire
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
