Ever dream of becoming an architect? Here's your chance to give it a try. After reviewing facts about triangles and quadrilaterals, pupils learn about the basics of architecture by talking to an architect or housing expert. They use...

Cook up a nice new kitchen. Future designers apply quadrilaterals to design a new kitchen floor. They create a tessellation and determine the area of the pattern. As an added component and real-world application, they must stick to a...

Let one's knowledge about polygons soar to new heights. Continuing their study of quadrilaterals, scholars watch a video to learn about the properties of kites and trapezoids. They see how to apply algebraic methods to solve for missing...

Intercept the class's learning on circles. Pupils learn the relationship between intercepted arcs and inscribed angles. The scholars use that information to find the relationship of angles in an inscribed quadrilateral and an angle...

Young geometers get practice with the algebra of angles in an extensive skills practice learning exercise. Supplementary, complementary, and vertical angle relationships are used, along with parallel lines cut by a transversal and...

In this quadrilaterals worksheet, 10th graders identify 10 different figures as they relate to quadrilaterals. They identify and/or make each quadrilateral illustrated on the sheet, including a trapezoid and a parallelogram.

In this shapes and designs activity, 10th graders solve and complete 6 different types of problems. First, they fill in the first two columns of the table show with their shapes. Then, students measure the interior angles of each...

In this geometry worksheet, students determine if a figure is a quadrilateral. If so, students continue to answer questions to determine whether it is a square, diamond, rhombus, rectangle, parallelogram or trapezoid.

If you like to start each day with a new math challenge or warm-up, this resource is a must have. It includes 36 slides, each containing a different math challenge that stimulates algebraic reasoning, problem solving, and basic math...

Work the problem shown in this video to learn how to determine the area of a parallelogram. Basic algebra, area, and the Pythagorean Theorem are used to find the missing value and solve the problem of area.

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

In this parallelograms worksheet, 10th graders identify and describe a quadrilateral, a diagonal, and a parallelogram in 7 different problems. First, they find the values of x, y, and z in each quadrilateral to prove that it is a...
