Slopes with Starburst
Students will use Starburst to conduct an experiment that analyzes slope. The data will be entered into TI-Nspire and evaluated. Students explore concepts such as flat/steeper slopes and constant versus varied slope. Students also simulate distance versus time graphs using meter sticks and hot...https://education.ti.com/en/activity/detail/slopes-with-starburst
Slope, Midpoint and Distance

Sums of Sequences
In this activity, students will develop formulas for the sum of arithmetic and geometric sequences. Students will then find the sum of sequences using the formulas developed.https://education.ti.com/en/activity/detail/sums-of-sequences_1
Trigonometric Patterns
Students will use the unit circle to examine patterns in the six trigonometric functions.https://education.ti.com/en/activity/detail/trigonometric-patterns
Here's Looking At Euclid
Students first use the familiar prime factorization method to calculate the GCD and LCM of two numbers. Second, they apply Euclid’s algorithm, an iterative process for finding the GCD, in conjunction with a formula for the LCM given the GCD. In order to use the algorithm, they must first grasp th...https://education.ti.com/en/activity/detail/heres-looking-at-euclid
Recursive Sequences
