Get out those protractors! Geometers measure interior and exterior angles of 10 polygons, including a 24-gon. They also calculate the interior angle sum of the 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.

Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....

How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate...

Explore some of the lesser-known shapes in this matching activity: oval, trapezoid, parallelogram, cross, and hexagon. Learners examine a set of the shapes and match them to a list of names. It may be confusing for some to...

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...

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...

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

Students practice measuring the interior angles of given regular polygons and create a formula for finding the measure of th interior angles of any polygon. They determine the relationships between the number of vertices's or sides in a...

Sixth graders find the perimeters of polygons and use perimeters to form polygons. In this perimeter instructional activity, 6th graders study vocabulary associated with finding perimeter such as polygon, line segment, variable, and...

Engage youngsters in exploring the wonderful world of shapes with this series of cut-and-paste activities. Offering a variety of materials from printable pattern blocks to a series of matching exercises, this resource will have your...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

In this angles in polygons activity, students determine the value of a missing angle measure. They find the value of interior angles and exterior angles. Polygons include triangles, quadrilaterals, pentagons, and hexagons. This...

In this geometry learning exercise, 3rd graders draw line segments into the shape and divide it into other shapes given. Then they divide the pentagon and hexagon in different shape parts using line segments. Students also write down...

This engaging presentation would be helpful for your young learners of geometry. Pupils are given clues as to what a shape may be, then they have to use those clues to guess what shape is being described. Shapes used are the circle,...

For this symmetry worksheet, students identify lines of symmetry in given polygons. They discover the correlation between the number of sides and the number of lines of symmetry. Students determine the lines of symmetry in irregular...

A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Students build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...

Each of these 10 shapes comes with a question for learners to answer as they analyze its attributes. They examine the following shapes: hexagon, trapezoid, pentagon, circle, diamond, parallelogram, rectangle, triangle,...

More than just a worksheet, the resource provides a thorough guide to navigate through the land of parallelograms. Filled with definitions and theorems, the resource supports learners through problems such as proofs and finding missing...

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

Trigonometry teachers often go off on a tangent, and here's a worksheet that proves it! First, young mathematicians use a formula with tangent to prove a formula correct for area. Then, they draw conclusions about the area of a circle...

Fifth graders investigate possible solutions to a word problem. They explore properties of polygons and right angles. Students demonstrate proper angle measurement. Students discover patterns.

Middle schoolers identify polygons.  In this polygon people lesson, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The lesson may be extended by allowing...

After learning that the sum of interior angles for triangles is 108 degrees, take it further to show that the sum of angles in any polygon is the same! Using hexagons, pupils practice finding the measure of the six congruent angles. Make...
