Quandaries, Quagmires, and Quadrilaterals
Students classify, flip, slide, and turn a quantity of quadrilaterals.
Curated OER
Investigate the Rigid Motions of Reflection, Rotation, Translation, and Dilation
Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.
Curated OER
How Tall Is That Flag Pole?
Pupils examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

Family Activity: Triangles and Quadrilaterals
In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...
Curated OER
Landscapes
Students explore landforms and landscapes. They demonstrate an appreciation for and examine how to recognize the attributes of landforms and landscapes. Students create a landscape and reflect on their painting.
Curated OER
Data Representation
Students solve real life scenarios using math. For this geometry lesson, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.
Curated OER
Transformation Trio
Students identify the transformation and rotation of polygons. In this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.
Curated OER
Learning about Shapes with Tangrams and the Net
Students use tangrams, student literature, and Websites to explore shapes.
Curated OER
Governor's Garden
Students review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...
Curated OER
The Delta Flier
Students make calculations in order to construct a kite in the shape of an isosceles right triangle. In this kite lesson plan students calculate altitude of their flying kites using a formula.
Curated OER
Similar and Congruent Triangles
Students create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.
Curated OER
Creating Tessellations
Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.
Curated OER
Fun With Symmetry
Learners manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.
Curated OER
Silly Symmetrical Names
Fourth graders participate in hands-on activities to introduce them to the concept of symmetry. They make a silly symmetrical picture out of their names after gluing them onto a larger sheet of construction paper. This is a really...
Curated OER
ABC's Transformer
Fourth graders design their own letter graph, and then produce the resulting graphs after a translation, reflection, and rotation. After a review of vocabulary, 4th graders create their graphs using crayons.
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
Patterns: A Stitch in Time
Learners recognize shapes, designs and numbers that form patterns. Using their surroundings, they identify common patterns. They create their own patterns in various software programs and share them with the class.
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.
Curated OER
Lines of Symmetry
In this math activity, students practice drawing the lines of symmetry for each of the polygons. They also draw mirror images for the figures.
Curated OER
Symmetrical Journals
Students identify symmetrical shapes around their classroom and make symmetry journals. In this symmetry lesson plan, students make drawings of symmetrical shapes inside their journals.
Curated OER
Circle Relationships
Students explore circles. In this geometry lesson, students explore the relationship between the circumference of a circle, the distance a ball travels, and the number of rotations the ball must make in order to travel a certain...
Curated OER
Transformations
Tenth graders recognize, perform and derive rules for basic transformations including translation, reflection and rotation. They also consider compositions, a combination of two or more basic transformations. Students explore both...
