Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....

Students view a video to discover how patterns in nature relate to math. They explore the concept of exponential growth by observing and creating fractals. They solve and design word problems.

Students calculate the volume and surface area of each shape. In this geometry lesson, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...

In this congruent triangles worksheet, 10th graders solve and complete 10 different problems to determine whether each set of triangles is congruent or not. First, they copy each diagram onto a piece of paper and mark up the paper with...

Students examine tessellations and their geometric properties. The lesson plan and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Students cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...

Students complete a variety of activities surrounding minerals, crystals, and mineralogy. They locate common minerals on a world map, complete a lab in which they identify the chemical and physical properties of various minerals, etc.

Students calculate the altitude of triangles.  In the web based lesson, students explore the interior distance from a given point in a polygon to its side.  They compute the sum of these lengths. Students read life...

Learners investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.

Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...

Pupils explore the concept of trapezoids.  In this trapezoids instructional activity, students identify legs and bases of a trapezoid.  Pupils discuss the similarities and differences between isosceles trapezoids and right...

Young scholars randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson plan, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new...

Students identify geometric patterns in quilts. In this geometry activity, students view various types of quilts and identify the geometric shapes. Students construct one hundred patch paper quilts using geometric shapes.

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Young scholars explore the concept of multiplying polynomials. In this multiplying polynomials lesson, students watch a video clip about basic math skills. Young scholars work in groups on an exploration about why a binomial squared...
