Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.

Students observe solids and identify parts that make up the surface area. In this geometry activity, students calculate the surface are of solids and cones. They find polygons and solids in the real world.

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.

First graders learn how use a ruler to measure common items. In this measurement lesson, 1st graders examine the numerical markings on rulers and learn that each number stands for a unit of measure. They measure 5 classroom items after...

Students construct triangles. In this geometry lesson, students create equilateral triangles. They also construct triangles where the sides are different. They use the lab to create and move shapes around with the Cabri program.

Students identify and use the similarity theorem. In this geometry lesson, students differentiate between congruent and similar triangles. They solve problems using the computer modifying shapes by dragging.

Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.

Fifth graders participate in a review game of geometry topics. In this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

Students solve word problems by using basic geometry. In this geometry lesson, students use geometric formulas to find the perimeter, area, and volume of objects. Students complete a worksheet.

Students classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

Students solve problems. For this math lesson, students write solutions using LOGO commands in order to help get the turtle to the pond.

Fourth graders examine mirror symmetry. In this symmetry lesson plan, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.

Students look around classroom and identify any patterns they see, describe patterns and explain why they are patterns, use pencil to demonstrate arithmetic patterns by tapping, practice predicting patterns by using Function Box, and...

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Students explore the complexity of handmade quilts and their designs by looking a real life samples.

Second graders describe a polygon in the form of a riddle.

Students study geometric images and polyhedrons. In this geometry lesson plan, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed...

High schoolers 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

In this plane figures worksheet, learners answer questions about the plane figures and their sides and corners. Students draw pictures to help them answer the six problems.

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

Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...
