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...

If you want a bigger garden, here's a task for you. Given the perimeter of a triangular garden, scholars determine the largest possible area. They then generalize their findings and extend the idea to other polygons.

Cover the floor with math. Pupils work to determine the proper shape to cover a kitchen floor. They first determine the number of tiles to purchase and configure their placement to reduce the amount of waste. Teams finish by creating a...

Dogs can't do math ... but people sure can! A set of five lessons has scholars apply math concepts to solve problems related to buying a new dog, such as designing a fence and a dog house, estimating how large the dog will become, and...

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

No need to change anything about the resource. The first of eight modules in the MVP Geometry unit focuses on transformations in the coordinate plane. It connects translations, rotations, and reflections to congruence, symmetry, and...

How are angles and sides related? Given several regular convex polygons, the video shows how to calculate the sum of their interior angles. The segment in a playlist on geometry shows how to find the measure of one angle if the polygon...

Build a pattern by rotating a figure around one of its vertices. A segment of an extensive playlist on basic geometry introduces the concept of tessellations through regular tessellations. The video shows how to create tessellations and...

It does not divide into 360 evenly, so it cannot work. The resource extends pupils' thinking about rotational symmetry. By asking for a figure with a rotational symmetry of a seemingly impossible angle, the activity requires learners to...

Going around is the same no matter the number of sides. An installment in a geometry playlist explains exterior angles of a convex polygon. The video presents the formula to find the sum of the angles along with the formula for finding...

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...

Colorado would probably object if Wyoming enlarged its borders. Scholars use an interactive map to change the borders of U.S. states to see how angles change. They then answer questions about regular and irregular polygons.

Let polygons be polygons. Learners identify reflections and rotations that carry regular pentagons and regular hexagons onto themselves. They then make generalizations about n-gons.

With a little imagination, you can make these construction tools work, too. A creative lesson builds upon the knowledge of construction tools to come up with other tools to use. Pupils learn how to construct a regular hexagon inscribed...

Once one is created, keep duplicating it until the construction is complete. Pupils use the power of a dynamic geometry software program to construct an inscribed regular hexagon within a circle. The scholars create equilateral triangles...

A prescription for inscribing polygons makes for an interesting lesson. Individuals follow a set of written instructions to construct both an equilateral triangle and regular hexagon inscribed in a circle. An extra handout allow learners...

Construct regular polygons using a circle as a guide. Scholars learn the process of inscribing regular polygons inside a circle using the central angle method. They practice their constructions on a variety of circles.

To locate the vertices, look no further than the radius. The assessment provides the pupils with a circle. Learners construct an inscribed regular hexagon in the circle using a straightedge and compass.

Discover the distance all the way around. The video introduces the concept of the perimeter of a figure. An explanation shows how to find the perimeter of a variety of polygons along with regular polygons. The presentation highlights the...

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...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

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...

One is chance, two is a coincidence, three's a pattern. Scholars must determine similarities and differences of a regular hexagon undergoing dilation. They look at lengths, angles, areas, and symmetry.
