Inscribing a Circle in a Triangle
In this activity, students bisect the angles of a triangle and find the incenter of the triangle. They find the distance from the incenter to the side of the triangle and use it as radius. With the incenter as the center, they inscribe a circle in a triangle. NCTM Geometry Standard covered: Anal...https://education.ti.com/en/activity/detail/inscribing-a-circle-in-a-triangle
Intersecting Lines and Vertical Angles
In this activity, students visualize and explore the angles that are formed when two lines intersect. By measuring angles formed by intersecting lines, they enhance their understanding of vertical angles, supplementary angles, and a linear pair. NCTM Geometry Standard covered: Analyze characteris...https://education.ti.com/en/activity/detail/intersecting-lines-and-vertical-angles

Circumscribing a Circle About a Triangle
In this activity, students use the distance of the circumcenter of a triangle to each vertex of the triangle as the radius and draw a circle using the circumcenter as the center. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and de...https://education.ti.com/en/activity/detail/circumscribing-a-circle-about-a-triangle
Say What You Mean!
This is a fun activity that has students determining how grades could be adjusted should a curve be given. Students will experiment with lists and stat plots to determine if their adjustments create a line or a curve when plotted on a graph.https://education.ti.com/en/activity/detail/say-what-you-mean
Midpoint of a Segment
Students review the basic geometry definitions of segment and midpoint, and learn to use drawing and measurement tools. They explore changes in measurements as the figure is altered. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes a...https://education.ti.com/en/activity/detail/midpoint-of-a-segment
Drawing and Measuring an Angle
Students learn to use drawing and measurement tools to measure angles. They explore and review types of angles as their measurements are altered.

Measuring Angles in a Quadrilateral
In this activity, use an interactive, and investigative approach to determining the sum of the interior angles of a quadrilateral. They use Cabri™ Jr. to draw, measure, and calculate the characteristics of the angles of quadrilaterals. NCTM Geometry Standard covered: Analyze characteristics and p...https://education.ti.com/en/activity/detail/measuring-angles-in-a-quadrilateral
Leaning Toward Christmas
Students will generate equations in an attempt to match the left side of a Christmas tree.https://education.ti.com/en/activity/detail/leaning-toward-christmas
Exponent Game
Students compare powers and decide whether to add or subtract values to a cumulative total so that the total stays as close to zero as possible.https://education.ti.com/en/activity/detail/exponent-game
Remember Me?
Students use the calculator to compute the value of expressions involving order of operations.https://education.ti.com/en/activity/detail/remember-me
Repeating Elevens
Students compute multiples of 11, 111, 1111, and so forth, search for patterns in the products, and write generalizations of those patterns.https://education.ti.com/en/activity/detail/repeating-elevens
Light Years Away
Students develop models for a light year and compare numbers written in scientific notation and in standard notation.https://education.ti.com/en/activity/detail/light-years-away
Going Out of Business
Students use the Pythagorean theorem to compute the diagonals of rectangles.https://education.ti.com/en/activity/detail/going-out-of-business
Magic Nines
Students compute multiples of 9, 99, 999, and so forth, search for patterns in the products, and write generalizations of those patterns.https://education.ti.com/en/activity/detail/magic-nines
Circle Around
Students compute the circumference and area of circles. They understand that the ratio of the circumference to the diameter is a value (3.14) called pi.https://education.ti.com/en/activity/detail/circle-around
The First Twelve Days of School
Students learn to organize data, look for patterns, and solve problems. They will count the number of "coins" in a variation of The Twelve Days of Christmas song. They will also generalize the patterns through symbolic expressions.https://education.ti.com/en/activity/detail/the-first-twelve-days-of-school
