Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Students identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Students then...

Students describe, make and compare polygons. For this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson plan. They make a set of tangrams and use them to compute area....

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Fourth graders explore polygons. In this polygon lesson, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.

Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.

Pre-schoolers identify things that make them a special individual. In this diversity lesson, they read the book Little Gorilla and discuss ways they are special and unique. Children create a birthday party for "Little Gorilla" and...

Fifth graders are engaged in sorting and classifying geometric shapes of various colors and sizes. They discuss the properties of these shapes and illustrate a range of classifications using Venn diagrams.

Fifth graders explore polygons. In this math lesson plan, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

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

Learners follow directions in the ABC of Symmetry to make a butterfly which shows a line of symmetry.

Fifth graders work with polygons.

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Third graders explore vocabulary associated with three dimensional figures.  In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

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

Tenth graders explore the structure and content of galaxies. Through discussion, lab, and hands-on activities, they discover the general structure of the three types of galaxies as well as the effect they have on the structure and...

Time to move on to nonlinear functions. Scholars create input/output tables and use these to graph simple nonlinear functions. They calculate rates of change to distinguish between linear and nonlinear functions.

Further your instruction on geometrical symmetry with an investigation of circles. Fourth graders come to realize that the lines of symmetry of a circle are infinite.

Develop an understanding of algebraic sequences through an exploration of patterns. Five leveled problems target grade levels from elementary through high school. Each problem asks young mathematicians to recognize a geometric pattern....

Students 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

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.
