Students listen carefully and put pieces together following the teacher's instructions. They point to the different shapes and sizes as they are being called out and count the number of items they have in front of them. They decorate...

Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson plan is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the...

In this symmetry worksheet, students identify lines of symmetry in given polygons. They discover the correlation between the number of sides and the number of lines of symmetry. Students determine the lines of symmetry in irregular...

Middle schoolers investigate the concept of two dimensional polygons. They complete a vocabulary chart with the teacher or in independently. Students are shown various polygons in order to classify them and then asked to draw one of them...

Students use the Pythagorean Theorem to explore sailboat design. In this Pythagorean Theorem lesson, two sides of a triangular sail are measured, and the theorem is used to calculate the third side. A worksheet, bulletin board design,...

Students calculate the distance between two points using the distance formula. In this geometry lesson, students derive the distance formula using the Pythagorean Theorem.

In this midpoints worksheet, 10th graders solve and complete 10 different problems. First, they find the perimeter of each illustrated triangle. Then, students determine the bases and median of a trapezoid. They also prove that two lines...

Fifth graders, using graphic and word processing software, create geometric patterns by performing elementary transformations.

Designers in Prague are not diagonally challenged. The mini-assessment provides a complex pattern made from blocks. Individuals use the pattern to find the area and perimeter of the design. To find the perimeter, they use the Pythagorean...

Viewers learn how to identify and perform a variety of transformations with a video that provides seven items on transformations. Pupils demonstrate their understanding of dilations, reflections, rotations, and translations. The video...

Introduce translations as transformations that move figures in horizontal and vertical distances with a video that shows how to translate the figures. A second video covers how to determine the translation that has occurred. Pupils...

The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another. 

Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Students solve the area for parallelograms,squares, rectangles, trapezoids, and triangles. In this geometry lesson, students compare and contrast two dimensional shapes and apply their properties to solving real life scenarios. This is a...

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...

This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...

Learners identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...

Students identify basic geometric shapes using Geogebra. In this geometry lesson, students work on a laptop as they explore different geometric shapes. They calculate the area and perimeter of triangles.

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

For this geometry worksheet, students answer questions about triangles and trapezoids as it related to the area of a shape. They make their own polygons and calculate the area.

Students measure the perimeter and area of their polygons. In this geometry lesson plan, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.
