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, 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...

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...

Lines of Symmetry
Drawing lines of symmetry helps scholars understand shape attributes, basic fractions, and equality. They determine how many lines each of these nine shapes has, using an example as reference. Consider having learners cut out a set of...

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,...
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
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...

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!

Line Symmetry
Teach your class about symmetry lines with this resource. This worksheet defines symmetry and explains lines of symmetry and how they work. Learners examine a variety of examples before drawing lines of symmetry in 5 figures. The...

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...

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...

Symmetry
Third graders find symmetry in nature. In this symmetry lesson, 3rd graders discover that symmetry is in nature and our everyday world. Students examine the alphabet for symmetrical letters then create their own artwork showing symmetry.

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.

Let's Learn about Symmetry
Students explore symmetry in architecture. In this cross curriculum art and architecture lesson, students fold paper to illustrate symmetry and identify symmetrical and asymmetrical shapes. Students observe photographs or take a walk...

Shape and Space: Symmetry
Students discuss and work with lines of symmetry. In this symmetry lesson plan, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.
