Students investigate the relationship between angles and their sides. In this geometry lesson, students prove why SSA does not work as a true angle side relationship theorem.

Fifth graders examine patterns and relate to equations to solve math problems.  For this patterns lesson, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.

Fifth graders use patterns, models and relationships to solve equations.  In this equations instructional activity, 5th graders define vocabulary for equations and complete worksheets explaining variables and solving problems.

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.

Learners explore polygons and their uses in careers. They also discover polygons shapes in manmade objects and nature. They use their acquired knowledge to construct a strong structure using polygon shapes.

Second graders practice unit fractions to identify parts of the whole and parts of a set. They utilize a variety of manipulative's including recipe boxes to get them started stirring up fractions. A multitude of books on fractions are...

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

In this enthalpy and entropy learning exercise, high schoolers read about the differences between enthalpy and entropy and answer three critical thinking questions about the reading.

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.

Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the lesson plan, they sketch each shape and identify their...

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.

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 define the properties of minerals and their uses in their world. In this multi-lesson unit, students contribute actively to discussions of mineral mining, mining methods and mine safety. A role play lesson asks students to...

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...

Fourth graders make models of three-dimensional figures and then use these play dough figures to observe and count the vertices, edges, and faces of the figure.

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 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.

Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...

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 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...

Students compare things that are greater than, less than, or equal to, compare the Earth to other planets, and list planets from greatest size to smallest size.

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.
