Parallel or Perpendicular-What's Your Inclination?
This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. (Topic - parallel and perpendicular lines)https://education.ti.com/en/activity/detail/parallel-or-perpendicularwhats-your-inclination
Angle Theorem
Students use the Cabri Geometry II Plus software to investigate the relationship between angle and ratio in a right triangle.https://education.ti.com/en/activity/detail/angle-theorem
Area of Triangle
This Cabri Geometry activity enables students to review the relationship between the height of a triangle and its perimeter and area.https://education.ti.com/en/activity/detail/area-of-triangle
Conics in Geometry
This lesson has students construct 3 conic sections through geometric definitions. Using the CABRI™ Geometry II application for the TI-89, students construct a parabola, an ellipse, and a hyperbola. (Topics - geometric shapes.https://education.ti.com/en/activity/detail/conics-in-geometry
Number of Regions - An Introduction to the TI-Nspire CAS
This activity uses the problem of determining the maximum number of regions formed by n lines in a plane to introduce new users to the TI-Nspire CAS. It illustrates the variety of features available on the TI-Nspire CAS, as well as the ability to look at one problem from multiple representations ...https://education.ti.com/en/activity/detail/number-of-regions--an-introduction-to-the-tinspire-cas
Who Needs Mixed Numbers?
Students divide and multiply mixed numbers and fractions in real-life examples relating to carpentry.https://education.ti.com/en/activity/detail/who-needs-mixed-numbers_1
What's So Special About 11?
Students will compute multiples of numbers in search of patterns. As a class, they'll discover patterns in multiples of 9; then they'll do the same with patterns in multiples of 11. They will then practice writing the rule for 11, both verbally and algebraically, to summarize the discovered patte...https://education.ti.com/en/activity/detail/whats-so-special-about-11
Can Pythagoras Swim?
Students will investigate relationships between sides of right triangles to understand the Pythagorean theorem and then use it to solve problems. Students will simplify expressions using radicals and exponents in this activity.https://education.ti.com/en/activity/detail/can-pythagoras-swim
What's the Fastest Way to Get Rich?
Students investigate exponential growth and discover patterns by exploring different scenarios involving money. They will learn how repeatedly doubling, or multiplying by two, can also be expressed exponentially.https://education.ti.com/en/activity/detail/whats-the-fastest-way-to-get-rich
The Antics of Statistics
Students learn/review some of the different measures of statistics and see how to use those measures to analyze a data set. Students also participate in a discussion about how statistics can be used to achieve a variety of results.https://education.ti.com/en/activity/detail/the-antics-of-statistics
Let's Count the Ways
Students will be introduced to the different ways to calculate numbers of outcomes, including using the counting principle. They will also evaluate expressions using permutations of data without repeat elements, both manually and on the TI-34 MultiView™ calculator.https://education.ti.com/en/activity/detail/lets-count-the-ways_1
