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...

Finding the Line of Symmetry
Can you find the line of symmetry? That's what your students will demonstrate by completing this worksheet. The task gets increasingly difficult as shapes are included that have one line of symmetry, no lines of symmetry, and multiple...
Curated OER
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
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...
Curated OER
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...
Curated OER
Trace a Line of Symmetry
In this lines of symmetry worksheet, young math whizzes analyze pictures of eight common objects and draw a line of symmetry for each.
Curated OER
Are the Dotted Lines, Lines of Symmetry?
Here is a geometry skills practice learning exercise in which learners respond to eight questions that require them to identify lines of symmetry.
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...
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
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
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...
Scholastic
Study Jams! Lines of Symmetry
Line up this lesson when introducing symmetry to your young mathematicians. Watch how two figures are introduced to different ways of folding and identifying whether or not they are actually symmetrical. Finish the lesson with a multiple...

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...
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...
Curated OER
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!
Curated OER
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!
Curated OER
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...

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...
Curated OER
Symmetry in Agriculture
In this symmetry worksheet, students look at 12 pictures. Students circle all the pictures that are symmetrical, and cross out all the ones that are not.
Curated OER
Lines of Symmetry - Rotational Symmetry
In this geometry skills practice learning exercise, students examine 3 images and determine whether or not they have rotational symmetry.
Curated OER
Lines of Symmetry
In this geometry skills practice worksheet, students respond to 3 questions that require them to identify lines of symmetry.
