Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...

Build a true understanding of division of polynomials. Learners use their knowledge of multiplying polynomials to create an algorithm to divide polynomials. The area model of multiplication becomes the reverse tabular method of division.

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...

If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...

Students calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Students identify the different properties of quadrilaterals. For this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...

Learners solve systems of equations. In this precalculus lesson,students solve linear equations using matrices. They use the Gaussian elimination method to identify the missing variables and simplify the linear equations.

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude, rise,...

Students investigate ways to save our environment by creating a recycled product.  In this sustainable materials lesson, students create a magazine holder by recycling a large cardboard box and gift wrap or wallpaper.  Students...

Students identify interior and exterior angles of polygons. For this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.

Second graders explore the concept of sound. In this sound instructional activity, 2nd graders discover what sound, vibrations, and pitch are through several experiments. Students watch a Power Point presentation that allows them to...

Fourth graders investigate regular polygons. In this regular polygon lesson plan, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
