A collection of two lessons, kindergartners will identify two-dimensional shapes in solid shapes. They will develop basic knowledge of the components that make up a sphere, rectangular prism, pyramid, cylinder, cone, and cube. Young...

Shapes in art, shapes in stories, shapes in the environment, shapes all around. A multi-part lesson that includes looking at the artist Paul Klee's work, reading books about shapes, taking a walk in the neighborhood and identifying...

Geometry students use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

Without ever using the actual term, this exercise has the learner develop the key properties of the midsegment of a triangle. This task leads the class to discover a proof of similar triangles using the properties of parallel...

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Middle schoolers explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Middle schoolers collaborate in graphing additional functions.

With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

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 identify patterns found in nature. In this algebra lesson, students model situation in nature using fractals. They investigate biological geometric structures and draw conclusion based on geometric concepts.

Learners are introduced to the basics of Geometry. Using cutout shapes, they identify whether they are polygons by using the properties of polygons. They practice drawing shapes they are going to be using on an everyday basis and...

Students explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Students explore fractal geometry. They do online explorations of fractals to discover applications of fractal geometry for a report.

Examine a coordinated geometry grid to decode the hidden message. Pupils write a coded message to their parents using letter coordinates from the grid.

Students explore how geometry is used on the composition of artworks by artists from different cultures. This activity is equally suited for a Math or Art classroom at the late-elementary or early-middle school level.

Students investigate the ties that architecture and math have in common. They focus on works of architecture in the world that is considered of great significance. Students use the internet to find building images from around the world....

Define and review math vocabulary. Use the CEENBoT to draw pictures that represent each vocabulary word. Pupils work in groups to play math pictionary.

Students investigate solids. In this geometry lesson, students use toothpicks and gum drops to solve problems. They create visuals to help them see what is happening to the shapes.

Sixth graders explore geometry by utilizing mathematical formulas. In this circumference lesson, 6th graders identify the difference between diameter, circumference and radius in a circle. Students review the formulas for finding...

Students relate the ratio of Pi to the diameter of a circle. In this geometry instructional activity, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and...

Eighth graders become engaged in a lesson in geometry to improve mathematical skills. They construct triangles, segments, and points using Geometer's Sketchpad to demonstrate how dilations of triangles and rectangles change geometric...

Young scholars explore polygons. In this geometry skills lesson, students complete an activity that requires them to solve geometry problems that involve polygons as they piece together geometric shapes. Young scholars analyze the shapes...

Students discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs and...
