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...

Simetria
Your Spanish students will see what symmetry looks like on a quadrilateral, triangle, and circle in this presentation. Large, bright shapes are displayed with lines of symmetry, followed by examples that do not show a line of symmetry....

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 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...

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...
Curated OER
Symmetry in Agriculture
In this symmetry instructional activity, students look at 12 pictures. Students circle all the pictures that are symmetrical, and cross out all the ones that are not.
Curated OER
Cutouts
Learners identify symmetry in shapes. In this geometry lesson, students fold paper to identify lines of symmetry. Learners create various symmetrical shapes using folded paper.
Curated OER
Symmetry All Around
Students explore geometry by creating a quilt square. In this symmetry lesson, students identify a list of items, designs, insects and animals which have either rotational or line symmetry. Students investigate symmetrical designs on the...
Curated OER
Geometry--Symmetry
In this symmetry activity, students identify and circle the shapes that are symmetrical in a set. There are four multiple choice questions.
Curated OER
Symme"tree"
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.
Curated OER
Symmetric Learning
In this symmetrical shapes worksheet, students recognize pieces of shapes. Students are given two shapes where they have half of the shape. Students are to draw the remaining half of the shape.
