Learners discover a method for determining the slope of a line by creating and comparing similar triangles. They fold coordinate grids to make three similar triangles then measure the sides to compare the relationships between the...

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related activity is Coordinate Grid: Mapping an Archeological Site.

Students investigate triangles and their properties. In this geometry lesson, students differentiate between similar and congruent triangles. They use the SSS theorem to help identify the triangles that are similar or congruent.

Young scholars examine an ISS EarthKAM image of farm land in Texas and New Mexico. They select sample region of image and count the number of fields in that region. They estimate how many fields are in the entire region.

Investigate geometric reflections in this geometry lesson. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own. They...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Young scholars investigate and solve Pythagorean triples. In this geometry instructional activity, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different...

Students investigate the Pythagorean triples. In this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.
