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 and Creating Tessellations
Students 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 .

Geometry Level 3
What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...
Curated OER
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,...

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
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
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...

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
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
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.
