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...

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...

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...

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...

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

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...

Fifth graders investigate the symmetry of pattern block shapes. Students, working in groups determine whether each shape has line symmetry, rotational symmetry or both kinds of symmetry. Students determine how many lines of symmetry the...

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson connects geometry, earth science, and delicious snacks to teach kids about ecosystems...

Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

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

Learners explore lines of symmetry. In this symmetry lesson, students divide and combine shapes along basic lines of symmetry. Learners explore symmetry in real life objects.

Students manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs students to an understanding of this crucial mathematical...

Third graders find symmetry in their body. In this symmetry lesson plan, 3rd graders look at different geometric shapes and identify which ones are symmetrical and find their line of symmetry. They measure body parts to the nearest half...

Learners explore reflection of polygons on a coordinate plane. They examine the relationships that exist between corresponding points and sides. 

Middle and high schoolers perform transformations. In this web based lesson, learners explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Students practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.

Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...

Sixth graders build figures out of tangrams. In this symmetry lesson, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of symmetry, and use...

Students are introduced to the concept of symmetry by examining different shapes and folding them into equal halves. They work in small groups focusing on finding the lines of symmetry of one specific shape. A symmetry booklet is made by...

Fifth graders discover lines of symmetry for shapes and everyday objects. In this lines of symmetry lesson, 5th graders use a butterfly outline to find lines of symmetry. Students analyze everyday objects for symmetry and use...

Fourth graders examine mirror symmetry. In this symmetry lesson, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.

Your learners collaboratively find the lines of symmetry in an equilateral triangle using rigid transformations and symmetry. Through congruence proofs they show that they understand congruence in terms of rigid motions as they...

Second graders demonstrate understanding of symmetry and identify objects that have symmetry. They use a mirror to get a visual illustration of what symmetry is. They create a collage of symmetrical pictures they find in magazines.
