Lesson Exchange: Polygons (Middle, Mathematics)

Roll the dice with this multimedia math lesson on probability. After first viewing a series of three short videos explaining probability, independent events, and dependent events, young mathematicians complete a set of practice...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

That shape is so weird, there's no way to find its area! Show your classes that they can use grids and known formulas to find the perimeters and areas of irregular figures. Pairs develop methods to break irregular figures into figures...

Add some variety to your school or district's math curriculum with this comprehensive collection of materials. Offering over 900 pages of Saxon Math lessons, worksheets, and activities, this resource is a gold mine for any middle school...

Don't be obtuse, this geometry unit is the just the right resource for educating the acute young minds in your class. From classifying and measuring angles, to determining the congruence of shapes, this resource covers a wide range of...

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 irregular...

Float like a butterfly, think like a bee! Build a huge hive, hexagonally! Find out the reason that hexagons are the most efficient storage shape for the honeybees' honeycombs. This neat little video would be a sweet addition to your life...

Investigate the area and perimeter of polygons in this geometry lesson. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape of...

At the end of the activity your learners will be able to classify a polygon by the number of ordered pairs given in a coordinate plane used as the vertices. this is the first video in a progressive series of four using geometry to solve...

Middle schoolers compute the desired length of a ramp that needs to go up three steps. The packet includes five challenge questions with answers and teaching pages to go along with each challenge question
