Good things happen when algebra and geometry get together! Continue the exploration of coordinate geometry in the third lesson in the series. Pupils explore linear equations and describe the points of intersection with a given polygon as...

Students investigate the properties and idea of the Pythagorean Theorem. In this algebra activity, students identify the different parts of a right triangle and relate it to the Pythagorean Theorem. They do a robotic experiment to...

Students find the length of the hypotenuse using the Pythagorean Theorem. In this geometry instructional activity, students solve for the different parts of a right triangle. They work the first problem with-the teacher then work on...

Seventh graders relate the Pythagorean theorem to the real world. In this algebra lesson, 7th graders identify important properties of the Pythagorean theorem and use it to solve word problems. They create a step by step plan to...

Students solve for missing sides using the Pythagorean theorem. In this algebra lesson, students derive the six trigonometric values using the right triangle. They relate the Pythagorean theorem to the distance formula.

Is there a relationship between powers and roots? Here is a lesson that asks individuals to examine the graphical relationship. Pupils create a table of values and then graph a square root and quadratic equation. They repeat the process...

Young scholars calculate the distance they will travel. For this geometry lesson, students use the TI and CBL system to make calculation of a certain path. They explore geography by calculating distances between different areas as it...

Using the Pythagorean Theorem to solve for missing angles, students evaluate right triangles and their properties.

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

The Pythagorean Theorem is a geometry pupil's best friend! Learners explain the equation a1b1 + a2b2 = 0 for perpendicular segments using the Pythagorean Theorem. They are able to identify perpendicular segments using their...
