Eighth graders engage in a lesson that is about classifying polygons with the focus being upon specific triangles and quadrilaterals. They conduct activities using cutouts for kinesthetic learners to help make connections while...

In this classifying triangles worksheet, 10th graders solve and complete 11 different types of problems. First, they state whether each segment shown is an altitude, median, or neither. Then, students solve for x and find the requested...

Ninth and tenth graders calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They solve problems involving scale drawings, models, maps or...

Middle and high schoolers solve and complete 29 various types of problems. First, they match each name with its correct formula. Then, students find the length of the missing side and the distance between the two points given. In...

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this instructional activity to...

Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...

Students define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

In thins triangles review worksheet, students examine 3 triangles and their measurements. Students classify them as acute, right, obtuse, equilateral, isosceles, or scalene.

Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students plant seeds and watch them sprout. Once growing plants are placed in different conditions and students record data about their growth. They graph the data.

Students explore the properties of rectangular prisms. In this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Young scholars create and give oral proposals for the construction of a gazebo using a blueprint created with Geometer's Sketchpad. They then build a gazebo model using the blueprints created and provide evidence why it should be...

Students estimate and measure triangles. In this geometry lesson plan, students identify the relationship between three sides and a triangle. They use the inequality theorem to decide if a triangle will be formed or not.

In this similar figure worksheet, students use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page worksheet contains 8...

Shapes are all around us! Kindergartenrs identify shapes in their world and guess the shape being described. They participate in a shape hunt.

Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Students explore the concept of quadrilaterals. For this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids,...

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.
