Module 6: Trigonometric Functions
Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Is This a Parallelogram?
If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...
Curated OER
Geo Jammin' By DeSign - Day 1, Lesson 1: Math in Motion
Second graders, through large screen monitor, study geometric design. They participate in a diagnostic assessment in which they use pnecils, scissors and paste.
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 students calculate altitude of their flying kites using a formula.
Curated OER
Mirror Tool
Students define properties of polygons. In this geometry activity, students differentiate between similar and congruent polygons. They identify and use the properties of solids to solve problems.
Curated OER
Spice Up the Basal
Fifth graders study English reading and writing skills as they participate in exciting interdisciplinary hands-on activities using a basal reading series.
Curated OER
Geo Jammin' By DeSign - Day 4, Lesson 22: Authentic Design
Students explore the complexity of handmade quilts and their designs by looking a real life samples.
Curated OER
Ge-Oh Boy, Oh Boy
Students listen to the book, Sam Johnson and the Blue Ribbon Quilt and discuss the art of quilting. They examine various symmetrical sewing designs, and identify reflection pieces, slides, and flips.
