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
Introduction to Absolute Value
In this activity students will explore the definition of absolute value using a number line, plot points to graph y = |x|, and use sliders to perform transformations with absolute value functions.https://education.ti.com/en/activity/detail/introduction-to-absolute-value
Recursive Sequences
In this activity, students will use the sequence mode of the graphing calculator to generate recursive sequences and then examine the values. They will also write recursive sequence formulas for given sequences.https://education.ti.com/en/activity/detail/recursive-sequences_1
Sequence Investigation
In this activity, students will use a calculator page to create an arithmetic sequence. Through this they will learn some of the vocabulary of sequences. Then students will then use slider functionality to explore the effect of each variable in the formula of the nth term of an arithmetic sequenc...https://education.ti.com/en/activity/detail/sequence-investigation_1
Area of the Missing Square
In this activity, students will be introduced to an area model for representing a quadratic equation. Students will explore the relationship between the value of b and c, in y = x2 + bx + c, form of the quadratic equation. The relationship will be examined with integer and non-integer values in o...https://education.ti.com/en/activity/detail/area-of-the-missing-square_1

The Open Box: An Exploration of Maximum Volume
The students will solve the problem of finding the maximum volume of a box cut from an 18 x 24 cm peice of paper in several ways. The student will actually cut out and form several different boxes. The student will fill the boxes with "starburst" candies and then use their TI-Nspires to analyze...https://education.ti.com/en/activity/detail/the-open-box-an-exploration-of-maximum-volume
Circle Product Theorems
Students use dynamic models to find patterns. These patterns are the Chord-Chord, Secant-Secant, and Secant-Tangent Theorems.https://education.ti.com/en/activity/detail/circle-product-theorems_1
Pythagorean Proofs
In this activity, students will explore proofs of the Pythagorean Theorem. Students will explore the proof of the Pythagorean Theorem using area of squares, area of triangles and trapezoids, and by dissection. Students will then be asked to apply what they have learned about the Pythagorean Theorem.https://education.ti.com/en/activity/detail/pythagorean-proofs_1
Points on a Perpendicular Bisector
Students will explore the relationship between a line segment and its perpendicular bisector. The concept of a point that is equidistant from two points is illustrated.https://education.ti.com/en/activity/detail/points-on-a-perpendicular-bisector
NASA - An Astronaut in Motion
...acility (ABF) are studying motor control and evaluating human physical measurement, variation, and movement. To study human movement, ABF researchers use motion capture technology. By using the motion capture technology, a segment of the body (e.g. the lower arm) can be tracked in 3-D as it move...https://education.ti.com/en/activity/detail/nasa--an-astronaut-in-motion
