Student will use the Measurement tools found in the Geometry menu options or model the image using functions on the Graph page
Reflections and Rotations
Students will reflect figures over the x- and y-axes. By studying what happens to the coordinates of the pre-image and image points, they will write rules for reflecting points over the axes. Students will then rotate figures about the origin, in both clockwise and counterclockwise directions. Again, they will study what happens to the coordinates of the pre-image and image points to write rules for reflecting points 90° and 180° about the origin.
Scaling the Geometry
This lesson involves scale drawings of actual images on the TI-Nspire handheld.
This lesson involves exploring the shapes formed from 3D figures cut by a horizontal and/or a vertical plane.

Getting "A-Round" Area
This lesson involves using sectors of a circle to form a parallelogram and, from this shape, investigating the area formula for a circle.
Angles for a Solution
This lesson involves looking at several sketches of intersecting lines and determining the measures of the missing angles using the facts about supplementary, complementary, vertical, and adjacent angles.
We've Got You Covered: 2D Area
This lesson involves using the geometry tools to measure the area of two-dimensional shapes from the faces of three-dimensional objects they see in pictures taken outside of the classroom.
The Pentagon Problem
This activity provides a simple, virtual "geoboard" that allows students to manipulate the polygon displayed on a unit grid. The grid squares provide a visual means of finding area.
Transformers in the Classroom
This lesson involves digitizing an image and transforming it on a graph.
What's Right about Triangles
This lesson involves examining a visual proof of the Pythagorean Theorem and supporting what happens geometrically.
This lesson involves the volume formula for cylinders, cones, and spheres.
Exploring Areas of Irregular Polygons
Explore different ways to find areas of irregular polygons using the three basic shapes of rectangles, parallelograms, and triangles.
Creating Parallel Lines and Transversals
Create a pair of parallel lines cut by a transversal and investigate the relationships among the angles that are created.
