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...

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...

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...

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...

Fifth graders analyze how to divide space or shape into mirror sections to create lines of symmetry. In this lines of symmetry lesson, 5th graders discuss symmetry in dance, math, and living. Students participate in a dance warm-up and...

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,...

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....

Students practice dance to divide the space or body shape into equal sections to create symmetry in dance. In this symmetry instructional activity, students practice symmetrical and asymmetrical movements in dance. Students participate...

First graders create symmetrical designs using a computer program.  In this lines of symmetry instructional activity, 1st graders review their symmetrical designs and discuss other ways symmetrical designs can be made. ...

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,...

Working on symmetry in your class? If so, this worksheet might be for you. Learners observe different triangles and quadrilaterals, determine which are symmetrical, draw in the lines of symmetry, and color the symmetrical shapes. In...

Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the...

Teach your class about symmetry lines with this resource. This instructional activity defines symmetry and explains lines of symmetry and how they work. Learners examine a variety of examples before drawing lines of symmetry in 5...

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

Students identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

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...

Students investigate the concept of symmetry. They use cut out shapes that are folded in order to practice identifying the lines of symmetry. The lesson is observed by the teacher working with students for the purpose of scaffolding and...

For this math worksheet, students practice drawing the lines of symmetry for each of the polygons. They also draw mirror images for the figures.

In this line of symmetry worksheet, 2nd graders fold a paper in half and cut two parts of a picture to show the line of symmetry. They answer 4 questions in which they color a domino to make it symmetrical. 

In this mirror lines and symmetry learning exercise, students solve 12 problems in which lines of symmetry are drawn and counted. This page is intended to be an online activity, but can be completed on paper.

Fifth graders explore the concept of symmetry using lines drawn through different shapes. The worksheet that is included in the lesson should be used to chart the lines of symmetry for the different shapes drawn.

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...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...
