Transformations – Reflections
Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...

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...

An Astronaut in Motion
How do you model the movement of an astronaut? The activity features software that uses an avatar to mimic movement. Groups work to determine the translation between the pre-image and the image. They then experiment with reflections in...

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.

Geometry: Translations and Reflections
Group work and participation is used to perform a specified translation or reflection. In this geometrical translation lesson, small groups of pupils are each given a shape to plot on a coordinate grid. Each shape is then translated or...

Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This unit...

Translation and Reflection
Bring about the change you want to see in the world or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to develop...
Curated OER
Anamorphosis
Students classify optical illusions according to their distinguishing characteristics. They create anamorphic art and use Mylar flexible mirrors to view and then they describe and analyze the optical illusion.

In The Garden
Middle schoolers 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.

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...

Reflections
Students investigate the concept of reflectons. They investigate how an image has a reflection that is symmetrical. They also choose household objects in order to have real life application for finding lines of symmetry.

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.

Geometry: Practical Applications of the Distance Formula
Students, 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...

Properties of Reflections
Students perform transformation on their polygons. In this geometry lesson plan, students identify the correct transformation of each shape. They move the polygons around on a coordinate plane. There are extension and homework activities...

REFLECTIONS OF SCIENCE
Students discover the different types of mirrors, their properties and some of their applications. They have already been introduced to some of the properties of light and have already experienced some of the different types of mirrors...

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.

Folding to Make Shapes
Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...
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
Shapes Are Everywhere
Third graders explore pattern blocks noticing their similarities and differences and share their observations with others. They classify shapes by discussing sides and angles and combine pieces to make new shapes.

Math is Beautiful
Students explore how geometry is used on the composition of artworks by artists from different cultures. This lesson is equally suited for a Math or Art classroom at the late-elementary or early-middle school level.
