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
Trig Patterns
In this activity, students will use the unit circle to examine patterns in the six trigonometric functions. Students will compare angles created with the x-axis in all four quadrants and discuss with one another what is happening at each coordinate as they move the point around the circle.https://education.ti.com/en/activity/detail/trig-patterns-@ns

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
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

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
Midsegments of Triangles
In this activity, students will explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle. First, students will construct and investigate one midsegment and the relationship of the new small triangle to the original triangle. Then, all three midseg...https://education.ti.com/en/activity/detail/midsegments-of-triangles_1
Interior & Exterior Angles of a Triangle
In this activity, students will measure interior and exterior angles of a triangle and make conjectures about their relationships.https://education.ti.com/en/activity/detail/interior--exterior-angles-of-a-triangle
Constructing Similar Triangles
Students investigate three different methods of constructing similar triangles.https://education.ti.com/en/activity/detail/constructing-similar-triangles
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
