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...

Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.

Students discuss and work with lines of symmetry. In this symmetry lesson, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.

Students follow directions in the ABC of Symmetry to make a butterfly which shows a line of symmetry.

Students create an art piece incorporating tessellating shapes, translational symmetry, reflectional symmetry,and or rotational symmetry. They are asked if they know the definition of tessellation. If so, students are asked what shapes...

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

Students listen to a read aloud of The Quiltmaker's Gift by Jeff Brumbeau finding examples of symmetry in the illustrations in the book.

Given the lines of symmetry in an equilateral triangle, your learners find where the pre-image vertices are mapped onto the new image. They explore the properties of equilateral triangles, the impact of reflections, and the...

Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...

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...

Students investigate the influence of the Enlightenment on American society and government. In this Enlightenment instructional activity, students work cooperatively in groups to define the principles of the...

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation. They perform...

Students discuss how color construct meaning in art. They will demonstrate a technical knowledge and creative use of formal elements and principals of design. Students then discuss the way their selection of color contributed to their work.

Fourth graders compare electricity and magnetism. In this science lesson plan, 4th graders discuss the concepts of electricity and magnetism and brainstorm examples of electrical and magnetic forces.

Young scholars explore the complexity of handmade quilts and their designs by looking a real life samples.
