Lines of Symmetry for Quadrilaterals
Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your...

Lines of Symmetry for Triangles
What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

Notan Collages - "Expanding the Square"
Notan is a Japanese word that expresses the interaction between light and dark. Learners explore Notan while creating dimensional art pieces that examine positive and negative spaces. They'll discuss the art of Notan, create their...

Sculpture in Balance
Learners discuss the difference betwen two-dimensional vs. three-dimensional art. In this art lesson, students discuss what symmetry or balance is in art and construct a symmetrical and an asymmetrical mobile.

Symmetry, Part 2
How can you tell if shapes are symmetrical? Fourth graders study 12 shapes, and draw lines down the middle of shapes that have symmetry. Once they are finished, they complete shapes that are missing their symmetrical sides. Some shapes...

Symmetry
Enhance your geometry lesson by working with shapes. Fourth graders follow lines of symmetry to complete ten shapes, most of them currently triangles. Have pupils color each half of their shapes to reinforce the idea of symmetry!

Bliss Butterflies Activity Sheet
In this life science instructional activity, students examine the 4 stages of the butterfly's life cycle and color in the black line pictures. They read the difference between symmetrical and asymmetrical objects before they complete...

Lines of Symmetry
Do your learners know that letters of the alphabet have lines of symmetry? Well, some of them do. Scholars examine nine symmetrical letters and draw in the line of symmetry for each (one of them has two!). They also complete six letters...
Curated OER
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...

Line of Symmetry
Where is the line of symmetry in these shapes? Review this concept using the visual guide at the top of the page, explaining how some shapes have multiples lines. Consider demonstrating this concept with large cut-outs, physically...
Curated OER
Symmetry
Fold these shapes in half and you'll have perfectly equal sides. Kids explore symmetry by completing 16 abstract shapes which have been cut off at the line of symmetry. They draw the mirror image, using several examples as reference. An...

The Same
These monsters are only half-drawn! Challenge scholars to observe the line of symmetry and draw in the other half to reflect the first half. There are six simple monsters in all, and scholars can color them in once finished (encourage...
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....
Curated OER
Symmetry
Where is the line of symmetry? Learners begin by drawing in a line to split three images evenly in half, using an example as reference. Encourage them to think about physically folding the picture to solidify this concept. Next, they do...
Curated OER
Symmetry
Do these dotted lines indicate symmetry? Some of them do, and scholars determine which ones in 12 different images. Because some of these are tricky, it may be helpful to have large versions of these shapes printed and cut out. This way,...

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.

Crazy for Cubes: Art and Science
Learners discuss Sol LeWitt and conceptual art, then analyze the differences in expressing a concept through model-based inquiry and aesthetic art criticism. They develop a geometric, scientific, or mathematical concept, then create an...

Principle of Art Balance
Reinforce a strong art vocabulary which can also apply to aspects of math and science. Kids read about various types of balance or symmetry found in art. They analyze three paintings based on vocabulary and read a how-to for creating...

Big Fleas Have Little Fleas
A benthic habitat hosts a vast collection of organisms and its structure influences the biodiversity. Middle-school marine biology explorers will discuss how corals impact structure, and therefore diversity, on the ocean floor. They draw...

Symmetry
A very clever marriage of social studies and math is offered in this presentation. Young mathematicians look at slides of a variety of flags of the world and try to find the line of symmetry in each. A clever way to practice symmetry!

Symmetrical Patterns
The class thinks about symmetry and patterns. They view several symmetrical patterns represented as dots with a mirror in between. They discuss which images are symmetrical and which are not, then color in dots to complete a few...
