Geo Jammin' By DeSign - Day 3, Lesson 14: Mirror, Mirror on the Wall
Learners explore characteristics of symmetry, write a definition, and locate the line of symmetry on a shape.

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,...

Lines of Symmetry for Quadrilaterals
Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

Using Symmetry to Create Corporate Logos
Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the alphabet and...

Lines of Symmetry
Young scholars practice dance to divide the space or body shape into equal sections to create symmetry in dance. In this symmetry lesson, students practice symmetrical and asymmetrical movements in dance. Young scholars participate in...

Medieval Mathematicians and Whimsical Windows
Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.
Curated OER
Reflection
Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.
Curated OER
Exploring and Creating Tessellations
Young scholars use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .
Curated OER
Building Buildings
Seventh graders investigate 2-D and 3-D objects. In this geometry instructional activity, 7th graders begin to understand spatial reasoning. Students look at pictures of the NYC Skyline and discuss what it looks like from different...
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
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
Symmetrical Journals
Students identify symmetrical shapes around their classroom and make symmetry journals. In this symmetry lesson plan, students make drawings of symmetrical shapes inside their journals.
Curated OER
Geometry: Practical Applications of the Distance Formula
Pupils, working independently and in groups, apply the distance formula to practical situations. After solving various problems, students in pairs design coordinate planes from the school blue print to measure the distance from the...
Curated OER
In The Garden
Students examine symmetry and transformation concepts. They create patterns that translate, reflect and rotate. Students participate in a variety of activities that explore transformation concepts through the context of a garden.
Curated OER
Transformation: Reflection
Tenth graders identify and analyze appropriate key vocabulary terms associated with transformations and reflection. Students experience creating and recognizing reflection with hands-on manipulations. Students discover real-world...
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
Symmetry Collage
First graders, in groups, studying symmetry, compose collages and bulletin boards.
Curated OER
Six Squares
Students create different shapes on grid paper. In this two-dimensional geometry lesson, students take turns outlining a shape made of six squares on the graph paper. They identify all shapes they see once everyone has had a turn.
Curated OER
Similar and Congruent Triangles
Learners create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.
Curated OER
Learning about Shapes with Tangrams and the Net
Students use tangrams, student literature, and Websites to explore shapes.
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
Silly Symmetrical Names
Fourth graders participate in hands-on activities to introduce them to the concept of symmetry. They make a silly symmetrical picture out of their names after gluing them onto a larger sheet of construction paper. This is a really...
Curated OER
Fold and Cut
Second graders explore line symmetry and the names and attributes of two-dimensional mathematical shapes. They study the context by folding and cutting out shapes to make a series of mathematical shapes.
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.
