Curated OER
Math Lesson: Rotational Symmetry
Students analyze lines of symmetry and rotational symmetry in designs. They practice dividing a shape along its line(s) of symmetry and discuss the relationship between lines of symmetry and number of sides as well as rotations.
Curated OER
Fun With Symmetry
Students manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.
Curated OER
Lines of Symmetry
Fourth graders demonstrate lines of symmetry using polygons, pentominoes, and block letters of the alphabet. They describe, identify, and analyze characteristics and properties of geometric shapes.
Curated OER
Exploring Lines of Symmetry
Students investigate the concept of symmetry. They use cut out shapes that are folded in order to practice identifying the lines of symmetry. The lesson is observed by the teacher working with students for the purpose of scaffolding and...
Curated OER
Lines of Symmetry
In this math activity, students practice drawing the lines of symmetry for each of the polygons. They also draw mirror images for the figures.

Draw the Other Half
How can you make the two halves symetric? Scholars use the concept of symmetry to complete five images which are only half-drawn. The fun part about this exercise is that they aren't copying geometric shapes. There is a face, sun, kite,...

Perfectly Puzzling Pentominoes
Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...
Curated OER
Symmetry: Reflections
In this symmetry instructional activity, students reflect a series of figures over given lines and rotate figures around given points as indicated.
Virginia Department of Education
Transformations
The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation. They perform...
Curated OER
Translations, Reflections, and Rotations
High schoolers are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three...
Curated OER
Rotational Symmetry
In this math worksheet, students examine the shapes given in two dimensions. They determine which ones are symmetrical to each other.

Geo Jammin' By DeSign - Day 3, Lesson 13: Reflections
Students use current knowledge to predict the meaning of line of symmetry. They explore symmetry using mirrors.
Curated OER
Symmetry
Learners 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...
