POLYGONS MADE TO ORDER: Math

A really useful resource contains 116 slides covering basic geometric concepts related to 2-D or plane shapes. Shape properties, translations, reflections, congruence, symmetry, and grid work are all laid out in a comprehensive and...

Here is a new twist on teaching the associative property of multiplication. The author of this presentation makes an analogy between the associative property and a couple getting married. The numbers, like people, are separate, but when...

Break down interior and exterior angles with this video. Using a pentagon, a teacher demonstrates how to find the interior and exterior angles of a polygon. She goes on to explain a few of the properties of these angles, writing down all...

A straightforward definition of the associative property of addition and multiplication, this resource could be used to help learners tackle the concept. You might consider giving the link to struggling class members so they can use it...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

Find a definition of regular polygon, and learn how to calculate the internal angle, external angle, and number of diagonals of a regular polygon. Also, learn how to find the area of regular polygons.

Classify this resource into the "Use" pile. Scholars use an interactive coordinate plane to plot polygons given coordinates for the vertices. They use properties to classify each polygon and answer a few challenge questions regarding the...

Model the distributive property with jars of fireflies! An interactive animation has learners manipulate the number of jars of fireflies to determine the number caught. Accompanying questions ask scholars to consider the multiplication...

Junior geometers use hands-on manipulatives to explore and describe the properties and attributes of a fundamental polygon, the triangle. They learn different kinds of angles and their measurements. This well-written lesson plan provides...
