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...

Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

Let the class' knowledge of geometry flow like water in an aqueduct. Future mathematicians research ancient Roman aqueducts and consider the geometric concepts necessary in their construction. They then use GeoGebra to create models of...

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...

Add a little algebra to the geometry. Class members learn about the Addition Postulate for segments and angles. The pupils use their knowledge of solving equations to find lengths of segments and measures of angles. Individuals apply...

Prove the best way to keep up in Geometry. Scholars first review algebraic properties from Algebra. Learners then use the properties to create two-column proofs to solve linear equations before completing algebraic proofs by providing...

What, you mean there is algebra in a Geometry class? Pupils review graphing and writing the equations of lines in slope-intercept form. The instruction follows the "I do, we do, you do" framework of a lesson. The instructor first...

Apply perspective to similarity. Individuals learn about the Side Splitter Theorem by looking at perspective drawings. Pupils use the theorem and its corollary to find missing lengths in figures. Next, they practice using the theorem and...

Combine geometry and tradition with a lesson that spotlights Navajo weaving. The book, The Goat in the Rug by Charles L. Blood and Martin Link hooks scholars before watching a video of Navajo people tending their sheep and beginning...

The 10th lesson in a series of 32, continues with the geometry of arithmetic of complex numbers focusing on multiplication. Class members find the effects of multiplying a complex number by a real number, an imaginary number, and another...

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...

Apply the Pythagorean Theorem to coordinate geometry. Learners find the distance between two points on a coordinate plane by using the Pythagorean Theorem. The vertical and horizontal change creates a right triangle, which allows...

Learners build connections between algebra and geometry as they study equation solving. The ninth instructional activity in the series of 28 asks pupils to write equations using angle relationships. After writing equations to model...

This is a mid-module assessment for the 16th lesson in 29 geometry lessons. Individuals demonstrate their understanding of concepts such as vertical and adjacent angles, constructing geometric figures, and triangle congruence criteria.

Pupils work on seven problems that use equations and expressions to solve geometry problems. The questions range from finding equivalent expressions to finding areas and volumes of figures. Learners apply their knowledge of angle...

When did letters become the same as numbers? Scholars learn about substituting numbers for letters to evaluate algebraic expressions in the seventh part in a series of 36. The instructional activity focuses on expressions related to...

The sky is the limit when printing custom 3-D shape templates from this site. Not only can you pick your shape and pattern, there is an option to upload an image for the different sides of the geometric shape. Let your learners have fun...

The quality of the images on this worksheet is poor, but it could be a simple way to review the principle of symmetry with young mathematicians. Students are presented with six images. They must first identify which of these pictures has...

Although the quality of the images on this worksheet is poor, this might be a quick and easy way to review the principle of symmetry with young mathematicians. Students are presented with six images. They must first identify which of...

Use this resource as an anticipatory set before a lesson on geometric shapes. A hidden picture slowly appears to reveal a circle, cube, and cylinder. It is a colorful presentation.

Use this resource as a way to kick off a lesson on geometric shapes. A hexagon, pentagon, and rectangle are hidden in each slide. Learners have to identify the shapes.

A lengthy presentation on geometric reflections is here for your young geometers. Learners consider a shape, then must choose between four reflections to find the one that is a true vertical, horizontal, or diagonal reflection of the...
