Curated OER
No-More-In-A-Line
Students and teacher discuss square windows and their symmetry. Students work on the problem given and discuss any difficult ideas. They work in groups to use a systematic approach to get all possible answers.
Curated OER
Lines of Symmetry
In this lines of symmetry instructional activity, students check either yes or no to determine whether 3 pictures have rotational symmetry or not. A reference web site is given for additional activities.
Curated OER
Symmetry
Students make a design with pattern blocks and then pass them on to the rest of the class. They have to make them symmetrical and complete the design.
Curated OER
Angles, Symmetry, and Quadrilaterals in Four Exercise Sets
For this angles worksheet, students calculate the size of angles, draw lines of symmetry, and form quadrilaterals in four exercise sets. The solutions are provided.
Curated OER
The Task of the Mask
Students discover historical value and use of different African masks through research and literature. Students also relate different customs and traditions of ethnic groups to the masks.

Unit 5 Math Vocabulary Cards (Grade 6)
Acute angle, line of symmetry, and vertex are a few terms you'll find in a set of 90 flashcards designed to reinforce math vocabulary. Included in the set are two types of cards; a word card printed in bold font, and a definition card...
Bowland
Three of a Kind
One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.

Transformations in the Coordinate Plane
Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...
Curated OER
Building Big and Strong
Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.
Curated OER
Transformations Using the Geometer's Sketchpad
Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.
Curated OER
Symmetry of the Southwest
Fourth graders examine mirror symmetry. In this symmetry instructional activity, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.
Curated OER
Lines of Symmetry
In this lines of symmetry instructional activity, learners check yes or no to tell whether sets of lines shown are lines of symmetry. A reference web site for additional activities is given.
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
Curated OER
Math: Shapes and More Shapes
Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...
Curated OER
Pattern Block Symmetry
In this symmetry activity, students fill in the shapes with pattern blocks to create a design so the dotted line is one of symmetry. Students trace and label each pattern and then explain how they know the design has a line of symmetry.
Curated OER
Sneaky Peeky Symmetry Book
Students examine lines of symmetry with different shapes. Then students create their own books of symmetry with different two-dimensional shapes on each page.
Curated OER
Boarding of Symmetrical Shapes
Second graders use geoboards to model polygons and to practice finding lines of symmetry.
Curated OER
Properties of 2D Shapes
In this math worksheet, students study 5 basic geometric shapes. Students write a description for each, naming the shape, telling about the edges, the lengths and the corners.
Curated OER
Symmetry
Students examine the concept of symmetry. They use photographs in front of a mirror to see symmetry. They write an explanation or drawing of how a mirror always produces a line of symmetry.
Curated OER
Symmetry In Nature
Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...
Curated OER
Turn Symmetry
Fourth graders observe geometric patterns to determine if they show rotational or point symmetry. They participate in the a demonstration lesson with a triangle. They create their own designs that show rotational or point symmetry.
Curated OER
Geometry and Symmetry
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.
