Middle schoolers identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Middle schoolers cut shapes out of...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

This heady calculus text covers the subjects of differential and integral calculus with rigorous detail, culminating in a chapter of physics and engineering applications. A particular emphasis on classic proof meshes with modern graphs,...

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...

Students calculate the sum of the angles of a polygon. In this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.

Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...

Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

First graders investigate symmetry in patterns by utilizing unifix cubes.  In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at.  Students utilize...

In this volume worksheet, students find the volume of 8 prisms.   Students are given the length, width, and height of each prism.

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Tenth graders explore congruent triangles.  In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson combines dry erase board activities and the use of technology.

Learners create tessellations with computer software while applying their knowledge of reflections, rotations, and translations.

Sixth graders examine a blue print and discuss the reasoning behind using blue prints. In this proportionality lesson,  students collaborate with their teammates to create a scale drawing. Once that is complete, 6th graders write a...

Students visit a local lake refuge and identify shapes they find in nature. They take pictures of the various shapes and use KidPix to draw shapes around the shapes in the pictures. They watch a slideshow of all the shapes found by their...

Students investigate circles and spheres. In this space shapes lesson, students compare and contrast two-dimensional and three-dimensional shapes. Students investigate the relationship between plane and space shapes.

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.

Tenth graders investigate the volume of a cylinder.  In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions.  The lesson progresses to the use of the formula to find...

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Students investigate the Pythagorean Theorem.  In this seventh through twelfth grade geometery lesson plan, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Students practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.

Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
