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...

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...

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.

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.

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...

In this reflections and rotations instructional activity, students reflect and rotate lines in graphs and draw lines of symmetry through patterns. Students complete 24 problems.

In this reflections and symmetry instructional activity, learners draw lines of symmetry in shapes and patterns and reflect letters over lines in graphs. Students complete 20 problems.

Pupils 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.

Learners examine Lao art techniques and practice replication and modification of Lao designs. Maintaining a symmetrical image, they embellish designs with imagery and background color. They discuss the students' works and note the...

Check for understanding with a set of math assessments. Fifth graders answer questions involving multiplication and division, median and mode, rotational symmetry, and graphing.

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...

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

Five steps walk scholars through the process of drawing a Monarch butterfly. Participants research the insect, make observations, trace, then color. 

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.

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...

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.

Young scholars engage in a lesson 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 lesson includes...

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.

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,...

In this whole and parts learning exercise, students study the shapes that each have a line of symmetry. Students draw the missing half so that each half is the same. Students then write if a diamond has more than 1 line of symmetry.

Learners explore mapping a rectangle onto itself using rigid motion concepts, geometric intuition and experimenting with manipulatives in a collaborative task.

Is it a calendar? A religious symbol? A political statement? One thing for certain is that Aztec sun stone designs remain an important symbol in Mexican cultural art. Young artists craft their own Aztec Sun design incorporating ideas...

Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

In this math worksheet, students find the vector parametric equation and symmetric equations for the line using two coordinate points.
