Lines of Symmetry for Circles
Further your instruction on geometrical symmetry with an investigation of circles. Fourth graders come to realize that the lines of symmetry of a circle are infinite.

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...

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...

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...

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...
Illustrative Mathematics
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...

Symmetry
Eleven problems provide pupils the opportunity to find the lines of symmetry or identify rotational symmetry. Scholars alter designs to make them symmetrical, learn to recognize signs that are symmetrical, and identify the type of...
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....

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
Identifying Lines of Symmetry and Creating Reflections over a Line
Fifth graders review the concept of a line of symmetry by using pieces of paper that have pictures such as, letters of the alphabet, polygons, and designs made from polygons in order to determine if they have symmetry. The fine,...

Symmetry
Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...
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
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
Second graders find the lines of symmetry in pattern blocks and alphabet letters. In this symmetry lesson, 2nd graders discuss what symmetry is, view examples of lines of symmetry and apply what they have learned by finding the line of...

Design a Flying Machine
Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...
Curated OER
Pattern Block Design
For this using pattern blocks to create a design worksheet, students read and apply criteria to create a design with pattern blocks, trace it, and draw lines of symmetry. Students complete four pattern block activities.

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...

Drawing Basic Shapes
Challenge your geometry class with this connect-the-dots activity! Scholars use a ruler to complete simple shapes through connecting dots in 6 shape-identification problems, and identify it from 4 choices: triangle, square, rectangle, or...

The Shape of Things
Investigate the attributes of polygons. A thorough set of lessons presents problem scenarios for elementary through high school classes. The first lessons focus on basic characteristics of polygons, including the line of symmetry. As the...

Unit 14 - Loci and Transformations
In this transformations worksheet, learners solve 25 short answer problems. Students dilate, reflect, and translate points and figures in the coordinate plane. Learners determine scale factors and lines of symmetry of figures.

Draw the Other Half
How can you make the two halves symetric? Scholars use the concept of symmetry to complete five images which are only half-drawn. The fun part about this exercise is that they aren't copying geometric shapes. There is a face, sun, kite,...
