Curated OER
Symmetry of Road Signs
Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.
Curated OER
Math Lesson: Rotational Symmetry
Students analyze lines of symmetry and rotational symmetry in designs. They practice dividing a shape along its line(s) of symmetry and discuss the relationship between lines of symmetry and number of sides as well as rotations.

Help Maggie Rebuild Her Airplane!
In this airplane worksheet, students build airplanes out of paper and test their accuracy while flying them. Students build 6 planes and fill out test logs to go with them.
Curated OER
Pumpkins
Third graders create a pumpkin lantern. They work in groups to illustrate the growth of a pumpkin seed. Students are asked what they think of when they see the color orange. They choice one person from the group to get a piece of...
Curated OER
Classifying Polygons
Students study polygons. In this math instructional activity, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.
Curated OER
Fractal and the Dragon Curve
Students explore Fractal designs. In this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.
Mathematics Vision Project
Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...
Curated OER
Geometry Flip Book
Learners investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
Curated OER
Triangles in Architecture
Students find triangles in the real world. In this geometry lesson, students analyze and identify properties of two and three-dimensional objects. They differentiate between similarity and congruence.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.
Curated OER
Symmetrical Journals
Students examine the concept of symmetry by studying the symmetry of symbols in a wall painting and creating journals with a symmetrical design. After a class review of symmetry and identifying the line of symmetry in several objects in...
