Exploring the Centroid of a Triangle
In this activity, students investigate what happens when all three medians of a triangle are drawn. They learn how to locate the centroid. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and develop mathematical arguments about geome...https://education.ti.com/en/activity/detail/exploring-the-centroid-of-a-triangle
Exploring Platonic Solids
This activity is best at the very beginning of a unit on solids. Students will observe Platonic solids using an interactive website (from the NLVM) projected to the whole class. Students will predict the number of edges, vertices, and faces of the five solids and record their predictions on a Lea...https://education.ti.com/en/activity/detail/exploring-platonic-solids
Investigating Segments in a Triangle
In this activity, students investigate the midsegments of a triangle as in the previous activity. They continue to explore these segments and extend their understanding of the relationships that exist between the slopes of lines containing the segments. NCTM Geometry Standard covered: Analyze ch...https://education.ti.com/en/activity/detail/investigating-segments-in-a-triangle
Betweenness and the Sum of Parts
In this activity, students' will explore the concepts of betweenness and the sum of parts visually, geometrically, and numerically for segments and angles using the Cabri® Jr. application. They will investigate how the sum of parts equals the whole.https://education.ti.com/en/activity/detail/betweenness-and-the-sum-of-parts
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
Concurrency & the Circumcenter
In this activity, students will explore the perpendicular bisectors of the sides of a triangle. Students will discover that the perpendicular bisectors are concurrent and that the point of concurrency is the circumcenter. Students should discover the relationship between the type of triangle and ...https://education.ti.com/en/activity/detail/concurrency--the-circumcenter_1
Is there a relationship between your fist and shoe size?
Students will measure the circumference of their fist and list their shoe size. The lists will be loaded using TI-Navigator™ in the activity center.https://education.ti.com/en/activity/detail/is-there-a-relationship-between-your-fist-and-shoe-size
