Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

A trip around the world sounds nice, but for now we'll just have to make do with Google Earth. Pupils use pictures of landmarks to apply geometry concepts. They determine whether each building has bilateral or rotational symmetry, search...

Ever dream of becoming an architect? Here's your chance to give it a try. After reviewing facts about triangles and quadrilaterals, pupils learn about the basics of architecture by talking to an architect or housing expert. They use...

Let the class' knowledge of geometry soar like the kites they create. After researching the history and science of kites, learners draw up a blueprint for their own kites. They then calculate the areas and perimeters based on the scale...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson plan would be an excellent choice...

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...

Fourth graders participate in a lesson that is about the finding of different fractional sizes with the help of pattern blocks. They define the vocabulary terms of numerator and denominator. The lesson also uses geometry and relates it...

Students gather information about the Melbourne Cup horse race in Australia. Then they study the geometry and physics behind the design of a racetrack. Students also work in small groups to problem solve and design their own board games...

In this Applied Skills Assessment worksheet, 5th graders complete a sample state assessment for Language Arts and Mathematics for 5th graders. They read a writing prompt and complete a writing activity that follows, answer various types...

Your geometry learners determine the measure of remaining angles in sets of three given that the other two are complementary or supplementary. From a diagram, they identify which angles are supplementary, complementary or congruent from...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

In this geometry lesson, 10th graders break down a circle and identify the different parts. They discuss chords, diameter, radius, circumference, major and minor segment. There are 42 problems broken down into 5 different sections.

A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

Use this geometry worksheet to have learners answer ten multiple choice questions based on their knowledge of transforming congruent figures.

Students investigate the area of squares and circles. In this geometry instructional activity, students calculate the area and probability of simple events. They work on a laptop using Safari.

Learners measure using the metric system. In this geometry lesson, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.

Young scholars conduct an experiment.  In this geometry lesson, students practice identifying, describing and comparing geometric solids.

Geometry novices will enjoy this approach to finding area, as they aren't required to include units or a formula. The main objective here is to segment a rectangle into columns and rows to create squares, which then are used to find the...

Just like a painting or the symbols on a flag, quilts can express ideas that reflect a cultural context, space, and time. The class discusses the history of quilt making throughout US history and what different types of quilts mean. They...

How can learners use algebra to solve a geometry problem? Help learners create an equation that shows the relationship between the number of sides of a polygon and the sum of the interior angles. Students are asked to divide the...

Use this task as an exit ticket for your eight graders during the geometry unit. All they need to do is identify the coordinates of a point reflected over y=2000. 

All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Your geometry learners will appreciate this net for a square pyramid. Copy, cut, and manipulate to explore the surface area or volume of a square pyramid.

Your geometry learners will appreciate this poster explaining the volume of a square pyramid. It is simple, to the point, and includes pictures.
