#### Methane Hydrates – What's the Big Deal?

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The lesson uses group research and a hands-on activity to help scholars...

#### Kangaroo Hop

Scholars play against three other participants to show what they know about geometric figures. Starting at the beginning, kangaroos jump from shape to shape to match the figure to the displayed word and make their way to the finish line.

#### Classifying Polygons: Lesson

For your eyes only: classify the names of polygons. After providing the definition of a polygon, the video introduces the two major classifications of polygons, concave and convex. The segment of a larger playlist on geometry continues...

#### Introduction to Polygons

How did polygons get their name? A brief video in the Socratica Geometry series explains the naming convention for polygons. Of course, this occurs after defining the term polygon.

Lesson Planet: Curated OER

#### Conjectures and Proof

Transform proofs using triangle rotations. By rotating a triangle around various points, class members develop proofs. Participants prove relationships of alternative interior angles formed by parallel lines and the sum of the interior...

Lesson Planet: Curated OER

#### Polygons

What shapes classify as a polygon? The resource provides the definition of a polygon and provides examples of polygons and shapes that are not polygons. The presentation gives an explanation of why each shape falls into the particular...

Lesson Planet: Curated OER

#### Polygons

Identify shapes based on their attributes. Second graders are tasked to color triangles, quadrilaterals, pentagons, and hexagons specific colors. The one thing these shapes have in common? They are all polygons.

Lesson Planet: Curated OER

#### Angles in Polygons

Show your class that finding angle measures is a regular calculation with a resource that provides 12 problems dealing with the measures of angles in regular polygons. Pupils use formulas for the sum of measures of angles in a polygon to...

#### Plenty of Pentagons

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape formed...

Lesson Planet: Curated OER

#### Shapes - Kindergarten

Extend scholars' learning experience with a unit consisting of five shape lesson plans, an extension activity, assessment, and rubric. Begin by reading a story about shapes, then conduct an overview and assign pupils' their first...

#### Unit 6 Math Vocabulary Cards (Grade 5)

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

#### Walking Polygons

Get up and move! With this kinesthetic activity, young mathematicians walk the sides and interior angles of given polygons. With pivoting and rotating, learners become familiar with the sum of the interior angles of a triangle.

Lesson Planet: Curated OER

#### Alike or Different Game

How are a circle and triangle alike? How are they different? These are the types of questions children will answer while playing this fun geometry game. Including a variety of conventional and unconventional shapes, this activity allows...

Lesson Planet: Curated OER

#### Draw Polygons Using Given Coordinates as Vertices

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...

#### What is a Prism?

I always thought a prism was a solid triangular shaped piece of glass that made rainbows when the light shined through it. Well, that is a prism, but that is only one example of a prism, as prisms are three-dimensional solids of a...

#### Spotting Polygons

See all sides of the story with a activity on geometric shapes! After studying the example at the top, which matches polygons with solid figures, second graders circle shapes that are named in the directions. Next, they match polygons to...

Lesson Planet: Curated OER

#### Naming Polygons

What polygon is this? Young geometers categorize shapes by circling all the quadrilaterals in a set of figures. Next, they write the names of 10 polygons using a visual guide as reference. Review the guide together before they start if...

Lesson Planet: Curated OER

#### 2-Dimensional Shapes: Naming Shapes

Get to know eight shapes by name: square, rectangle, triangle, pentagon, hexagon, and octagon. Young geometers write the correct name below each of these shapes, using a word bank for guidance. Then, they draw two of the shapes (hexagon...

Lesson Planet: Curated OER

#### Naming 2-Dimensional Shapes

Inside each of these two-dimensional shapes, scholars identify the figure by writing its name. There is a word bank for them to work from, but some shape names are used multiple times. There are six identifiers they use: pentagon,...

Lesson Planet: Curated OER

#### 2-Dimensional Shapes: Drawing Shapes

Some of the best practice with shape identification comes from drawing the figures first-hand. Young geometers draw nine two-dimensional shapes: rectangle, circle, square, pentagon, hexagon, octagon, triangle with three equal sides,...

#### What is a Polygon?

What makes a figure a polygon? Does it have three or more sides? Is it a closed figure? If the answer is yes to both of those questions then it's a polygon. But wait! Some of these polygons have special names based on the number of sides...
