You're safe, when calculating the odds of stealing second base! Learners compare the rate of a runner to the distance the ball travels, in a lesson that explores right triangles and measurement. Full of discussion questions and fun...

View a tree designed by Pythagoras. Pupils watch a video as a tree is built by using squares representing the side lengths of a right triangle, with each side of the squares becoming the side of another triangle. Learners come up with...

Which truck should the fire department purchase? Given a scenario with three different ladder trucks, pupil compare the height the ladders will reach. They determine which ladder trucks meet the cities' requirements and provide a...

When is the distance formula not accurate? Referencing a map of the school, pairs determine the walking distance between two locations. Creating coordinates for each location, pupils determine the distance between the two points and...

And he's ... safe? ... out? It's up to your scholars to decide! Provided with the speed of the runner and ball, learners develop a plan to determine which reaches the base first, the ball or the runner. While the distance from home to...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Measure that shadow, and you'll find the height of the building! Learners study concepts related to right triangles during this extended unit project. They identify right triangles in the world, find heights of objects using similar...

This is a great resource to keep daily material aligned to standardized assessments. It offers complete multiple choice and short-answer practice with a wealth of opportunities for customization. Offer it as a whole,...

Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was...

An excellent resource for a geometry class, as well as for an electrical engineering course. A thorough reference sheet covers geometric shapes such as triangles, parallelograms, and circles, as well as 3-D shapes and the Pythagorean...

Participants who use this resource will apply the Pythagorean Theorem to show whether or not the shaded triangle inscribed in a rectangle is a right triangle. Once all of the sides on the shaded triangle are found, it is important that...

Learners practice finding the areas and patterns within a square and explore the concept of quadratic functions. They observe and record the area values in a table, plot a graph of Area versus Distance and complete a variety of student...

Students answer multiple choice questions about the Pythagorean Theorem. The questions questions are self-checking and hints are provided.

Test your knowledge on the attributes of triangles. There are eleven levels that may be completed with or without a timer.

This resource allows users to test their geometry knowledge.

You can pick up some valuable pointers on how to apply the Pythagorean Theorem here. When you finish working your way through the pages you can take an on-line "Test Bite," and check your understanding.

The introduction of this lesson has students verifying the famous Pythagorean Theorem with a hands-on proof. Students will then apply the Theorem in one of two ways: by solving for the side lengths of a right triangle and by determining...

Finding the third angle of a triangle becomes easier by the explanation and examples presented.
