Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

Students are introduced to the concept of symmetry by examining different shapes and folding them into equal halves. They work in small groups focusing on finding the lines of symmetry of one specific shape. A symmetry booklet is made by...

Learners create three-dimension models demonstrating exponents, multiplying and dividing of fractions, and the use of repeating patterns in tessellations, mirror images, and tiling.

Students visualize a universe with fewer than three spatial dimensions. They consider how more than three spatial dimensions could exist in the universe.

Students listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Fifth graders classify triangles. For this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students 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. Students describe the reflection of rotational symmetry...

Young scholars study facial expressions and create a face jug. In this facial study lesson plan, students look at images of face jugs through history before drawing thumbnails of facial images. They use the coil method to make a jug, and...

Learners study bone size, structure and shape. They use various geometrical shapes to make a skeleton and produce a poster depicting the skeletal system and its functions. They arrange the pictures into the five sections, glue on...

Students work in groups to create the planets of the solar system.  In this planets instructional activity, students create a hanging solar system taking into account the size, shape and position of the planets.  Students...

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Students grow crystals in the lab using solutions. In this crystals lesson plan, students set up a crystal growing apparatus using a sugar solution with a thread attached to a piece of copper wire that is inserted in the solution....

High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...

Pupils explore the midsegment of a triangle in the geometry instructional activity. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the...

Eighth graders create artwork inspired by the work of Victor Vasarely. In this op art lesson, 8th graders explore color theory and color mixing. Students create ten shapes to use in their artwork and over the course of two weeks,...

Using the Twist™ application, elementary schoolers design their dream room. They follow the prescribed steps to calculate width, length, perimeter, and surface area in order to create a 2-dimensional representation of their dream room...

Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...

Building blocks have more uses than simply entertaining children. Young mathematicians calculate the volume of a given cube, and then calculate the volume and surface area of a prism formed from multiple cubes.

Wouldn't it be great to work in a candy factory? Learners get their chance as they first design a carton for a candy that meets certain requirements. They then examine and analyze nets and explanations in sample student responses.

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

Create geometric cups by interpreting directions, informational text, and mathematical concepts. Critical thinkers apply geometric theory (congruent shapes, patterns, symmetry) to actual directions to create a cup that holds Kool Aid....
