In this geometry worksheet, 10th graders complete an indirect proof and order the sides or angles of a triangle. Also, students determine if a triangle can have sides with the given lengths. The two page worksheet contains twelve...

Discover a new application of the Pythagorean Theorem. Learners prove and apply the converse of the Pythagorean Theorem in the 17th lesson in a 25-part series. The examples ask learners to verify right triangles using the converse...

What in the world is the zeroth power? Examine the patterns of exponents as they apply to the zeroth power. Scholars apply the zero property to simple exponential expressions in this fourth lesson in a series of 15. The examples include...

Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...

Learners engage in a lesson plan that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the...

In this interval worksheet, students find integrals of functions, use the first derivative test to classify points, and find the local and global extrema. This one-page worksheet contains eight multi-step problems.

Math whizzes read a series of slides describing steps to solving linear equations. They view a slide-show presentation. Each page, or slide, presents a different topic. Topics include: defining a linear equations, inverse operations,...

Students identify 3-D geometric shapes through different pieces of artwork. They examine and identify segments and angles. Students act out shapes and create a piece of artwork. Additional cross curriculum activities are listed.

Students investigate the theorems of ASA, AAS, AAA and ASA. In this geometry lesson, students discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by two rays...

Students investigate Pick's theorem by completing a lab. For this geometry lesson, students construct polygons using cabri software. They calculate the area of polygons and identify the vertices of each shape.

Students illustrate the concept of balancing equations using a Four-Pan Algebra Balance. In this balancing lesson plan, students visualize why it is necessary to add or subtract the same quantity on both sides of an equation when solving...

Students explore the concept of vertex-edge graphs.  For this vertex-edge graphs lesson, students try to construct a graph with a given diameter, number of vertices, size, and planarity.  Students construct various vertex-edge...

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...

Students research Babylonian mathematics. They calculate simple surd numbers. Students find the fractional form of rational numbers expressed as decimals. They work with numbers in base 60.

There are different types of reading meant for different texts. Discuss four of these with your emerging readers. When does one perform an extensive or intensive reading? When does one skim or scan a text? How are these all different? 

Pupils show through art how major human events have changed American Culture. Students write in a journal to keep track of studying that is done during the unit. They also create an oral report.
