Proofs are usually an intimidating assignment. An engaging lesson focused on geometric proofs may reduce the anxiety! Pupils choose between several triangle proofs to complete and work on completing them. The...

Add a touch of winter flair to geometry practice with a pattern block mat shaped as a snowflake. Preschoolers and kindergartners can work on both shape recognition and pattern identification as they form beautiful snowflakes.

This is great go-to activity for those spring or fall days when the weather beckons your geometry class outside. Learners start with a small tree, devising strategies to accurately estimate the leaf count. They must then tackle the...

A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...

Young mathematicians connect vectors to geometric shapes by watching a video that expresses vectors in relation to the sides of geometric figures. They then apply what they learned by completing a worksheet of practice questions.

Cover the field. Pairs investigate two different rolls of astroturf to cover a football field. The learners determine which type of roll is the most cost effective. Scholars write letters to the athletic director explaining their...

Strengthen young geometric muscles with this exercise in finding surface area and volume. Six problems provide practice at determining the surface area and volume of two solid figures shown in cubic units, deciding which to find given a...

In this sea squares worksheet, 10th graders solve 5 different problems that include various geometrical figures. First, they draw a number line using one color. Then, students draw 2 obtuse angles and 3 isosceles triangles with different...

Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

There are several ways to estimate the area if the curve does not create nice geometric figures. The presenter introduces the idea of using areas of rectangles to estimate the area under the curve. Pupils use four types of Riemann Sums,...

Students identify and visualize congruent and similar two-dimensional geometric figures. They recognize that rotations, translations, and reflections do not change geometric figures. Students participate in activites in which they...

Middle school geometers determine the area of a shape on a geoboard or dot paper and draw figures that meet given area conditions. Working as a class, they develop and discuss various ways to draw geometric shapes with specified...

There's a reason this worksheet is done in groups! Tricky word problems give geometry scholars a challenge as they use prior knowledge about shapes to find the area and perimeter given a few measurements. Students will enjoy discovering...

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Fourth graders examine the properties of geometric solids. Given geometric figures, they brainstorm observations. In groups, 4th graders identify solids and discuss the physical properties. Each student creates a Venn diagram and...

In this area learning exercise, students complete a ten question multiple choice test by finding the area of various geometric figures. This is an interactive learning exercise.

Students are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...

In this TAKS worksheet, 4th graders answer three multiple choice questions that pertain to objectives covered on the Texas state test. Students answer quesetions regarding geometric figures andplotting on a numberline.

Students use geometric shapes to describe body parts. In this geometry instructional activity, students use geometry vocabulary as they discuss body parts. They practice drawing bodies using shapes based on a wooden model that is poised...

Your algebra learners interpret algebraic expressions, in order to compare their structures, using a geometric context. They also discern how the two expressions are equivalent and represent a pattern geometrically and algebraically.

Create geometric cups by interpreting directions, informational text, and mathematical concepts. Critical thinkers apply geometric theory (congruent shapes, patterns, symmetry) to actual directions to create a cup that holds Kool Aid....

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

Geometric shapes are used in math and in art. Learners discuss the various names, dimensions, and attributes of geometric shapes, then apply that knowledge to design a vase. They use 3-D shapes to make a cubist-style vase out of clay.

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...
