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

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
Conditional Statements
In this activity, students construct examples of conditional statements such as parallel and perpendicular lines. After completing the conditional statement, they will write the converse, inverse, and contrapositive and determine if each is true.https://education.ti.com/en/activity/detail/conditional-statements
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
Back to the Basics
Students learn and use the basic undefined terms and defined terms of geometry. The activity does include some drawing practice on the handheld.https://education.ti.com/en/activity/detail/back-to-the-basics
Midpoint Quadrilateral
This problem presents an opportunity for students to think about properties of quadrilaterals, and also to work on confirming observations through geometric reasoning.
