Polygon Teacher Resources

Six lessons make up the Geometry Unit 9: Area of Polygons unit module. Pupils review the formulas for finding the area of parallelograms and triangles. They apply previous learning of trigonometric ratios and the Pythagorean Theorem to...

One's knowledge of angles should measure up to expectations. Scholars watch a video to learn about angles in polygons. They first see how to partition a polygon into triangles to find the sum of the interior angle measures. They then...

Looking for all things third grade Common Core math? Here is the collection you've been waiting for! Third grade math curriculum is rigorous and opens up the doors to bigger algebra concepts that learners will use their entire lives....

Before diving into the formulas for area, show where the formulas connect to the shape of the figure. The four videos look at different shapes and by decomposing them, they end up relating directly to their area formula.

Geometry Unit 10 contains six resources that cover surface area and volume. Scholars first watch a video explaining the basic terminology of three-dimensional figures, such as prisms, lateral edges, bases, and faces. They then learn how...

The point of this collection of 12 videos is to introduce learners to three basic parts of geometry—points, lines, and planes. The presenter provides definitions, shows how to classify shapes, provides examples, and shows how to use...

Imagine taking a complete geometry course remotely! Eleven units make up the My Geometry course. Each unit follows the Flipped-Mastery cycle of learning, divided into two semesters. Pupils watch and take notes on a video that details the...

Four lessons make up Unit 8 in the Flipped Math Algebra 1 module. Each lesson contains an instructional video, practice sets, and corrective assignments. The first lesson looks at function notation, domain, and range. The video...

Seventeen short assessments are designed to test scholars’ knowledge of basic Algebra 1 concepts. Pupils determine the houses that are a given maximum distance from a school, complete charts to show equivalent scale factors, and...

Get help when teaching 3D shapes in Geometry by using these resources to introduce classification, practice labeling, and apply this knowledge to other types of problems.

Good assessments are hard to find—assessments that address content standards and fit into standard class periods. The six assessments in the middle school collection are 80-minute forms, divided into two 40-minute sections, and are...
