Creating a Reflection
Investigate geometric reflections in this geometry lesson plan. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own....

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...

Congruent Segments
The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another.

Reflecting a Rectangle Over a Diagonal
Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.

Mixing in Math: Growing Plants
Whether you have your class plant seeds or begin when sprouts are visible, math skills are used here to predict and track growth over time. Straw bar graphs show plant height on a given day while the graph as a whole shows changes over...

What Is It Like to Be You?
Two poems, "What it is like to be you" and "I am more than what you see," provided young scholars an opportunity to reflect on how others see them versus how they see themselves. After reading the poems, individuals write their stories...

Exploring Symmetry
Young scholars 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
Plane Mirror Images
Learners view a demonstration to investigate mirror images. In this plane mirror lesson, students view a teacher demonstration of a plane mirror and the images it creates. They use meter sticks to investigate the angles of reflection and...
Curated OER
Tantalizing Tangrams
Students identify polygons and develop spatial and fractional relationships and geometric concepts by using ancient Chinese puzzle of tangrams. They develop an appreciation of the folktale by identifying its elements and then writing...
Curated OER
Geometric Transformations
Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.
Curated OER
Transformations and Matrices
There are four activities in this extensive lesson covering the identity matrix and scaling, the linear representation of translations, the linear representation of rotations, and reflections. In small groups, they use the Cabri II...

Why Does SAS Work?
Your geometry learners are guided by questions that help them use the language of reflections to explain the Side-Angle-Side congruence between two triangles in this collaborative task. Given a sample solution, declaring the triangles...
Illustrative Mathematics
Congruent Triangles
Geometers prove that triangle PQR is congruent to triangle ABC by describing any combination of rotations, reflections, and translations that would prove it so. There is only this single task on the handout, but a detailed explanation of...

Angles Activities
A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

Human Slope
Middle and high schoolers explore the concept of slope. In this slope lesson, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid....
Curated OER
Symmetries of a Quadrilateral II
Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.

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,...

Graphs of Exponential Functions and Logarithmic Functions
Graphing by hand does have its advantages. The 19th installment of a 35-part module prompts pupils to use skills from previous lessons to graph exponential and logarithmic functions. They reflect each function type over a diagonal line...
Curated OER
Dihedral Figures
Middle and high schoolers perform transformations. For this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.
Curated OER
Transformation
In this transformation worksheet, students identify and solve 10 different problems that include various images. First, they determine whether each object illustrated is a mirror image or reflection of the other image in the problem....
Curated OER
Transformations
Sixth graders discover transformations. In this graphing lesson plan, 6th graders explore visual examples of plotting transformations as they review translations, rotations, and reflections. Students also practice solving problems that...

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
Reflections of Symmetry
Students use video and the Internet to identify examples of bilateral and radial symmetry in the world around them. They create symmetrical reflection designs using pattern blocks and paper.
