How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

Students create a Hexaflexagon using a formula. In this calculus lesson, students apply the definition of delta epsilon as it relates to limit to create a shape using creases. They relate the same rule to triangles and investigate angles.

Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

Middle schoolers study the triangle inequality. They will identify, compare, and analyze attributes of two and three-dimensional shapes. Then they develop vocabulary to describe the attributes. They also use manipulatives to analyze the...

Students use the inequality theorem to solve triangles and their properties. For this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.

Ninth graders select and build one of five different paper airplane designs and test them for distance and for time aloft. Part of this activity is designed to explore NASA developed software, FoilSim, with respect to the lift of an...

Students identify different geometric shapes, and arrange them artistically in original jewelry designs.

Seventh graders investigate geometric shapes using tessellations. In this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Students make jewelry using different shapes from magazines, tissue paper, cardboard, and other materials. In this making jewelry lesson plan, students complete this hands on activity to discuss how shapes are used.
