Quilt Squared
Students study West Virginia quilts. In this mathematics lesson plan, students use symmetry, geometric shapes, and patterns to create their own quilt square.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.
Curated OER
A Cylinder Workshop
Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.
Curated OER
Tessellations: Use Angles To Show That Shapes Will or WIll Not Tessellate
Students observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.

Surface Area of Three-Dimensional Figures
Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...
Curated OER
Sphere Dressing
Geometric design makes a fashion statement! Challenge learners to design a hat to fit a Styrofoam model. Specifications are clear and pupils use concepts related to three-dimensional objects including volume of irregular shapes and...

How Do Dilations Map Angles?
The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure.
Curated OER
Looking at Circumference
Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.

Symmetry
Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...
PBS
Geometry: Hide and Seek
A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...
EngageNY
Rotations, Reflections, and Symmetry
Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...
Alabama Learning Exchange
"I Saw the Sine"
Discover trigonometric ratios that complement each other. Using two videos, the lesson introduces the trigonometric ratios. The class discovers the relationship between the sine and cosine of complementary angles.
Curated OER
Worksheet 17 - Area
In this area worksheet learners read story problems, determine the necessary information to solve the problem. They find the amount of material needed to construct three-dimensional figures. Students determine the greatest and least area...
Curated OER
Graph It
Elementary and middle schoolers engage in a lesson of graphing in quadrant I of the coordinate plain. They use the graph to create shapes and symbols. While using a graphing calculator, they locate the points on the coordinate plane. In...
Curated OER
Coordinate Plane
Tenth graders plot points on a coordinate plane. In this geometry lesson plan, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.
Curated OER
Introduction to Curve Stitching - Line Designs
Students develop their awareness that straight line segments can produce the illusion of a curve and helps them recognize and describe number patterns and geometric fundamentals.
Curated OER
Tessellation Lesson Plan
Learners produce original tessellations, using equilateral triangles where three unique symmetrical faces rotate, use shape, pattern/repetition, and color to create a striking composition, and create "beasties" inspired by bestiaries of...
