Students study geometric images and polyhedrons. In this geometry lesson, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed...

Fourth graders find the perimeter of a geometric shape by adding the lengths of the sides. They find the area of a square or rectangle by counting square units. Students use multiplication to find the area of a rectangle. They estimate...

Fourth graders design a figure using the given geometric shapes from a set of tangrams. They manipulate common shapes to analyze and make new figures. They complete a worksheet associated with the lesson.

Students explore and compare abstraction of human forms in various ancient cultures and by creating self-portraits using geometric shapes. They identify which geometric shapes form the following features: face, nose, arms, torso, legs,...

Students develop their awareness that straight line segments can produce the illusion of a curve and helps them recognize and describe number patterns and geometric fundamentals.

Students explore geometry in Navajo culture. In this geometry lesson, students search for different geometrical shapes in Navajo art. Students then create their own rug or jewelry design using geometrical shapes.

Young scholars analyze characteristics of geometric shapes. They find shapes in their environment, and communicate why it is like the shape of their choice and not like another shape.

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...

In this visual math puzzle worksheet, students work in groups to find the answer to 6 math puzzles. They work with geometric shapes and symbols.

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...

In this transformations and congruence worksheet, 10th graders solve and complete 5 different types of problems. First, they calculate the length of a line giving their answer in 3 significant figures. Then, students prove that two...

In this properties of angles, lines and triangles worksheet, 10th graders solve and complete 28 different problems that include determining the measurement of various figures shown. First, they use the geometric properties and theorems...

Students differentiate between inductive and deductive reasoning. In this geometry lesson, students identify congruent figures and examine logos for congruency.

In this geometry lesson, 10th graders fold a dollar bill to make a tetrahedron. They analyze geometric shapes and apply it hands on.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Students look at the geometry in an artwork. In this art history/geometry lesson, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines, angles, and...

Young scholars identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have...

Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Pupils explore the midsegment of a triangle in the geometry lesson plan. 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 triangle. The...

Eighth graders find the circumference and diameter of several lids, show the relationship of the two measurements and derive the formula for finding the area of a circle. In this area of a circle lesson plan, 8th graders find...

Students explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram being put...

Sixth graders view a video of tessellating an egg shape. They focus upon the problem solving strategies used and how tessellation geometry was used to construct the three dimensional figure. They create their own tiling patterns.

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