Transformations
How does something go from here to there? Describe it with a transformation. Young mathematicians learn how to translate, reflect, rotate, and dilate an image.
Curated OER
Symmetry
These symmetrical shapes are only half-completed, so scholars finish them by drawing the other side of the line of symmetry. Because your class won't recognize these abstract shapes, they will get authentic practice with this objective....

Pointzero: Confined
Groups plan their escape carefully. Three three-tiered puzzles help a story character escape their situation, each involving integer sequences, transformations, and geometric constructions. The teacher resource includes slides and...
Curated OER
Reflection
Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
Curated OER
Reflection: Student Worksheet
In this math worksheet, students will work independently to trace a stencil on an x-axis. Then students will follow a procedure to trace the image on the horizontal line of reflection. Students will observe that reflections and rotations...
Curated OER
Reflection
In this math worksheet, students practice their skills in constructing reflections of shapes that are on a grid. This worksheet has 13 problems for the students to solve, and includes an answer sheet.
Curated OER
Symmetry in Butterflies
Students create a butterfly displaying a mirror image of itself to show that it is symmetrical. In this symmetry lesson plan, students go over symmetry in different shapes and identify patterns in butterflies.
Curated OER
Lines of Symmetry
Fourth graders identify lines of symmetry using reflections and then construct figures that have one or more lines of symmetry. In this symmetry lesson plan, 4th graders use sets of shapes, pattern blocks, a mirror, and more.
Curated OER
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
Symmetry with Shapes
Students analyze a symmetrical stamp design with an equal balance of light and dark to create a pattern in succession. In this shape design lesson, students review concepts of sign, symbol and language across cultures. Students analyze...

Reflection of Light With Two Plane Mirrors- Double Mirrors Placed at a Number of Angles
Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.
Curated OER
Unit 7 Transformations
In this transformations worksheet, students observe the errors in the reflection of a picture. They determine the number of transformations needed to complete a grid. Students perform reflections according to directions and solve...
Curated OER
Exploring Symmetry
Students use a software program to create artwork and to manipulate images to study mirror and rotational symmetry. They take pictures of items in their environment in which they identify symmetry.
Curated OER
Tantalizing Tangrams: What Are Transformations?
Students use the Internet to learn about transformations and tessellations. In this geometry lesson, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry. Students...
Curated OER
Transformations
In this algebra worksheet, students identify different transformations based on the x and y axis reflections. They use vectors to do their translations. There are 28 questions.
