Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

What does a geometric farmer drive? A protractor, of course! A set of assessment worksheets prompts learners to use a protractor as they measure angles, name angles, and identify lines. Use the video as a way to...

Learn about constructing figures, proofs, and transformations. The seventh unit in a course of nine makes the connections between geometric constructions, congruence, and proofs. Scholars learn to construct special quadrilaterals,...

Students investigate shapes. In this dimension and orientation of shapes lesson, students identify and color shapes, use shape stamps to form animals, glue shapes together to make other objects and describe how shapes are used.

Pupils establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Fourth and fifth graders work in pairs  explore quadrilaterals. In this problem-solving lesson, learners participate in hands-on activities that require them to identify, describe, compare, and classify quadrilaterals. This is meant...

Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Using a word bank, mathematicians fill out a crossword puzzle using 9 clues. Each clue describes a shape, using details such as the number of sides, angle degrees, and the shape category. For example: "A quadrilateral with four equal...

In this geometry worksheet, students analyze the different properties of parallelograms related to their angles, sides and diagonals. There are 5 problems with an answer key.

Students are introduced to the concept of symmetry by examining different shapes and folding them into equal halves. They work in small groups focusing on finding the lines of symmetry of one specific shape. A symmetry booklet is made by...

Third graders use various shapes to identify polygons and understand symmetry. They explore pattern blocks noticing their similarities and differences, then share with other team members. They draw 3 polygons in their journals and...

In this quadrilaterals worksheet, 10th graders solve and complete 34 various types of problems. First, they fill-in the family tree with the names of the shapes of quadrilaterals shown. Then, students list the quadrilaterals that have...

In this geometry instructional activity, students identify important properties of parallelograms. They identify properties of the sides, angles and diagonals. There identify special parallelograms also.

Fourth and fifth graders learn to classify quadrilaterals and use more than one name for each. They follow the directions and classify three quadrilaterals. There are also activities which can be done with a partner.

Fourth graders discuss and examine examples of the different types of angles. After learning the names of the geometric shapes students identify the types of angles and then complete the Kidspiration activity, Identifying Angles.

Fifth graders examine how to make tessellations. In this tessellation instructional activity, 5th graders review the meaning of the word "polygon" while the teacher shows them various examples. They practice making tiling patterns or...

For this geometry worksheet, learners construct polygons and calculate the different angles formed by each shape. They construct circles, trapezoids, and rectangles and answer 20 questions.

In this geometry worksheet, 10th graders solve problems with quadrilaterals. They calculate the sum of the angles, find missing angles and identify properties of quadrilaterals. There are 16 questions with an answer key.

In this similar figure learning exercise, students use similar figures and indirect measurement to determine distance.  They use proportions of similar figures to determine scale figures.  This two-page learning exercise...

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...

Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

In this geometry review game worksheet, students use the provided game cards and calling cards to play a Bingo-like game. Students learn geometric terms while playing a group game.
