Curated OER
Figure This
Second graders identify congruent figures and match shapes using transformation. They work in groups, utilizing a worksheet imbedded in this plan to gain practice identifying congruent shapes.
Curated OER
Math/Technology: Symmetry
Fourth graders, using KidPix, use stamps and pencil tools to illustrate which pictures have symmetry. They add text boxes to explain their answers in math terms. Students practice skills in rotation, reflection, and translation on an...
Curated OER
Tessellation Quilt Squares
Fifth graders design a "quilt block" that has a tessellating pattern to help create a class tessellation quilt. They describe relationships between two- and three-dimensional shapes and analyze attributes and properties of geometric...
Curated OER
Symmetrical Journals
Young scholars examine the concept of symmetry by studying the symmetry of symbols in a wall painting and creating journals with a symmetrical design. After a class review of symmetry and identifying the line of symmetry in several...

Ck 12: Physical Science: Mirrors
[Free Registration/Login may be required to access all resource tools.] How a mirror forms images and how to distinguish between real and virtual images, and the different types of mirrors and the images they produce.
Exploratorium
Exploratorium: Science Snacks: Cylindrical Mirror
In this investigation, see yourself as others see you by using a cylindrical mirror instead of a flat mirror.
Exploratorium
Exploratorium: Science Snacks: Spherical Reflections
Investigate the behavior of light that is reflected off a spherical mirrored surface.
Exploratorium
Exploratorium: Science Snacks: Corner Reflector
By creating a kaleidoscope using a set of hinged mirrors students can see themselves as others do! This activity uses mirrors to create multiple images of an object.

Alex: How Light Travels
In this lesson, the students will be experimenting to show how light shines in a straight line. They will also be experimenting to see how light reflects using mirrors. The students will be working in cooperative learning groups to carry...

Texas Instruments: The Closer I Get to You Ti 83
Here's a group activity your students can do to learn about rational functions. Students will use properties of reflections together with measuring tapes, mirrors, and masking tape to find a function that relates height of a reflection...
Texas Instruments
Texas Instruments: Finding the Shortest Path
Students discover the shortest distance light travels from an object to the human eye, as the light from the object reflects off a single mirror. In the process they learn about reflection in a line, congruent angles, angle bisectors,...
