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

They will use this information to compute future "good" and "b...https://education.ti.com/en/activity/detail/biorhythms-and-sinusoidal-functions
Transformations: Two Functions or Not Two Functions
Students create original artwork using all functions and conics studied throughout the course. Lines and absolute values, conic sections and whatever else they can stick in a "y=" are combined with some calculator tricks to make works of art that the students are really proud of.https://education.ti.com/en/activity/detail/transformations--two-functions-or-not-two-functions
Balloons
This activity is about gathering data to create a scatter plot and then look at a line of best fit. Students will measure the circumference of a blown up balloon and then they will time how long it takes the balloon to deflate. They will enter this information in to their lists and then graph t...https://education.ti.com/en/activity/detail/balloons
