Mirror, Mirror I
How do you see yourself? Young mathematicians consider whether it's possible to view their whole bodies in a mirror with a length that is half their height. They write a letter to a friend explaining their positions mathematically.

Backwards Writing: Reflections and Symmetry
Why is "ambulance" written backwards on emergency vehicles? Young geometers apply principles of symmetry to translate words written backwards. See if your school or district subscribes to Jobland, where you can view a clip that explains...
Balanced Assessment
Writing and Sketching Resource
Picture this—the class creates pictures using functions. Here, learners build functions to model specific graphic criteria. They use their knowledge of parent functions and transformations to create the perfect function.

Mirror Symmetry/Mirror Images
Students explore lines of symmetry in geometric shapes. In this geometry lesson plan, students construct angles using mirrors and rubberbands, then predict the number of images that will appear in the reflection. Students reproduce lines...

Mirror, Mirror on the Wall, Who Needs Math in Life at All?
Students think and talk about the ways in which they use math throughout the day. They add each way to a "math in real life" bulletin board and reflect in writing on the ways they use math.

Symmetry
Is this the line of symmetry? Scholars analyze 12 images to determine whether or not the dotted line in each reflects symmetry. There are three examples for them to reference before they start, so consider reviewing these together before...

Building Word Problems
Sixth graders study addition and subtraction facts. In equal groups, they play a race game to correctly solve addition and subtraction problems. Using a PowerPoint presentation, the teacher demonstrates how to write word problems and...
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.

Lines of Symmetry, Shapes and Symbols
Which shapes are symmetrical? Third graders decide which shapes have lines of symmetry, and which shapes are not symmetrical. They work on 13 shapes and symbols, four of which have lines already drawn through them. Use this resource to...
