Symmetry of Flags
Students explore, examine and study the symmetry of the flags of individual countries in the EU. They identify and describe the reflection and rotation symmetries of two-dimensional shapes and assess how symmetry changes with respect to...
Curated OER
Symmetry of Flag
For this symmetry of flags activity worksheet, students examine the symmetry of the flags of the nations of the European Union.

Slope
What does slope have to do with lines? Pupils work with lines and determine the slope of the lines informally and with the slope formula. Groups use their knowledge to calculate the slopes of parallel and perpendicular lines. They also...

End-of-Module Assessment Task: Grade 6 Math Module 3
The last installment of a 21-part module is an end-of-module assessment. Individuals show their understanding of positive and negative numbers on the number line, absolute value, and the coordinate plane in a variety of contexts.

Triangle Inequality
Students discover that the sum of the lengths of any two sides of a triangle must be greater than the third side. They are shown how a triangle is formed using three strips such as that the triangle is seen inside the strips.
Illustrative Mathematics
Is This a Parallelogram?
If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...
Curated OER
No-More-In-A-Line
Students and teacher discuss square windows and their symmetry. Students work on the problem given and discuss any difficult ideas. They work in groups to use a systematic approach to get all possible answers.

Geometry Exam
For this reflections and symmetry worksheet, students draw lines of symmetry in shapes and patterns and reflect letters over lines in graphs. Students complete 20 problems.
Curated OER
Geometry Practice Exam
In this reflections and rotations worksheet, students reflect and rotate lines in graphs and draw lines of symmetry through patterns. Students complete 24 problems.
Curated OER
Symmetry
Students make a design with pattern blocks and then pass them on to the rest of the class. They have to make them symmetrical and complete the design.

Draw a Monarch
Five steps walk scholars through the process of drawing a Monarch butterfly. Participants research the insect, make observations, trace, then color.
Curated OER
Transformations Using the Geometer's Sketchpad
Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

Symmetry of the Southwest
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.
Curated OER
Absolute Value And Symmetry
Students engage in a instructional activity that is concerned with the concepts of absolute value and symmetry. They define the meaning of absolute value and graph functions and study the corresponding line and its symmetry. The...
Curated OER
Symmetry
Students examine the concept of symmetry. They use photographs in front of a mirror to see symmetry. They write an explanation or drawing of how a mirror always produces a line of symmetry.
Curated OER
Symmetry and Tessellations
Sixth graders investigate tessellations and their origins. Students trace triangles to form a tessellation. They measure the angle of equilateral triangles. Students locate the line of symmetry, they create geometric squares,...
