Students make three dimensional shapes with nets. In this nets lesson plan, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use...

Students investigate properties of circles. In this geometry activity, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Teach your class about symmetry lines with this resource. This worksheet defines symmetry and explains lines of symmetry and how they work. Learners examine a variety of examples before drawing lines of symmetry in 5 figures. The...

Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry lesson, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and spheres. They...

Students construct tangram pieces. Then they make observations and explore patterns with the pieces.

Learners build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Learners describe the reflection of rotational symmetry...

Students identify lines of symmetry.  In this symmetry activity, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

Middle and high schoolers identify and analyze fractals and research information using the Internet to locate information about them. They look at fractals in relation to nature and other real world situations. Pupils create several...

In this polygons instructional activity, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.

Seventh graders use block letter writing to help classify polygons. They use their own names which helps to keep them engaged during the lesson. Finally, 7th graders play a classification game naming different polygons.

Fifth graders work with polygons.

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

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. 

Students view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...

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

In this geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

In 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.

Tenth graders plot points on a coordinate plane. In this geometry lesson, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

Young scholars 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.

In this geometry worksheet, 10th graders answer questions about right triangles by identifying the 3 sides of the triangle. They analyze the different shapes of polygons and relate them to right triangles to find the sides using the...

In this math worksheet, students review concepts in algebra and geometry in preparation for the State Exam. They review slopes and functions, area and perimeter. There are 27 questions.

In this circle worksheet, students solve ten multiple-choice questions concerned with the area, radius, diameter, and circumference of a circle.  The solutions are provided by clicking on the "show answers" button on the bottom of...

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