Pitter, Patter with Patterns (Geometry, Patterns, and Classification)
Here's a great way to introduce your kindergartners to the world of shapes, patterns, and geometry. Learners are separated into groups. They perform hands-on graphing, sorting, play games, and work together to make a class quilt that...
Stitching Quilts into Coordinate Geometry
8th - 11th CCSS: Adaptable
Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project comes with...
End-of-Module Assessment Task - Geometry (module 1)
9th - 10th CCSS: Designed
Have you hit a wall when trying to create performance task questions? Several open-ended response questions require a deep level of thinking. Topics include triangle congruence, quadrilaterals, special segments, constructions, and...
The Complex Geometry of Islamic Design
5 mins 7th - 12th CCSS: Adaptable
Discover the prevalence of geometric design in Islamic culture with this wonderful informational video. It begins with an overview of the complexity of designs dating back to the eighth century during early Islam, and then delves into...
Introduction to VSEPR Theory (2 of 2) - Variants
9 mins 9th - Higher Ed CCSS: Adaptable
Everyone's heard of the Lone Ranger ... but what about the Lone Pair? Part two in a mini-series from a JFR Science playlist explains the geometry of molecules with unbonded pairs of electrons. The narrator explains each family of...
Geometry Practice: Transformations, Isometries, and Tessellations
9th - 12th
Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...
Tangent Lines and the Tangent Function
11th - 12th CCSS: Designed
Construct tangent lines and make the connection to tangent functions. An informative lesson reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...
