Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...

In this Geometry worksheet, 10th graders solve problems involving the properties of a regular pyramid.  The two page worksheet contains a combination of seven multiple choice and free response questions.  Answers are...

Ten similar worksheets plus their answer keys are included in this resource. Each simply displays three right rectangular prisms with their length, height, and width printed on them. Fifth graders apply the formula for the volume of a...

Students explore the mathematical properties of traditional American Indian lodges. They examine the effect of increasing sides of a polygon, calculate the surface area of prisms and cylinders, and construct a classroom size pyramid...

Students identify the ratios of different triangles. In this geometry lesson plan, students identify the similarity and differences of triangles. They use the navigator to move the sides of the triangle around.

In this geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

Students explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships: vertical,...

Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

In this SAT practice test activity, 12th graders answer 10 short answer questions. Questions are from a variety of topics, but mainly ask about geometry concepts. The test is self-scoring.

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...

In the second of two similar worksheets, anglers compute missing angles when given an alternate, supplementary, or complementary value. There are six problems to solve, but each of them requires two to four solutions. This is a nice...

In the first of two similar worksheets, geometers compute two to four unknown angles when given an alternate, supplementary, or complementary value. There are six multliple-step problems to solve. This is a nice challenge for your...
