Rotations in the Plane
In this activity, students will explore the properties of rotations and the relationships between the original and image figures.https://education.ti.com/en/activity/detail/rotations-in-the-plane
Ryan's Puppy Problem
This problem can be used in Geometry of Algebra. Ryan desires to build a rectangluar fence to keep his puppy in. What shape should he use if he has 8 meters of fencing?https://education.ti.com/en/activity/detail/ryans-puppy-problem
Triangle Properties Assessment
This activity uses Cabri Jr. to assess the students' knowledge of various segements related to triangles: perpendicular bisector, median, angle bisector, midsegment, and altitude.https://education.ti.com/en/activity/detail/triangle-properties-assessment
The Tangent Ratio
In this activity students explore the tangent ratio. Students construct a right triangle using perpendicular lines, and a line that forms the hypotenuse of the triangle. When students construct the hypotenuse line it is very important that the second point that forms the line is not on the perpen...https://education.ti.com/en/activity/detail/the-tangent-ratio
Transformational Puppet
This activity is designed to reinforce the concepts of reflections and translations by having the students create a virtual puppet using Cabri Jr. As they construct their puppets, students will reinforce their understanding of reflections and translations by making predictions about the location...https://education.ti.com/en/activity/detail/transformational-puppet_1
REAL LIFE REAL WORLD - Avalanche Rescue
When hikers and skiers go into terrain with a risk of avalanches, they take safety equipment including avalanche rescue beacons.
