A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

Here is a real-life lesson plan! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore...

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

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....

An informative video and handout provide the basic information needed to reflect any pre-image across either of the axes on the coordinate plane. The printed resource provides a preview of reflecting across lines other than an axis....

Doing is more effective than watching. Learners use spaghetti to discover the relationship between the unit circle and the graph of the sine and cosine functions. As they measure lengths on the unit circle and transfer them to a...

In this rigid transformation worksheet, learners follow directions to translate, reflect or rotate a figure in a coordinate plane. Examples and explanations are provided at the beginning of the document. This two-page worksheet contains...

An instructive lesson provides the basics on how to perform rotations on the coordinate plane. The handout also covers rotating about a point other than the origin and how to perform a series of transformations. 

Flip, turn, and slide about the coordinate plane. Pupils define the rigid motions and experiment with them before determining the relationships of the slopes of parallel and perpendicular lines. The sixth unit in a nine-part series...

Students watch the teacher draw on the chalkboard and try to determine the form being drawn. They use questions to determine Quadrant #1 of a coordinate plane.

Students consider the relationship between form and flight and investigate the history of man made flight and how wing shape and flexibility affects the maneuverability of an aircraft.

Fourth graders use computer drawing tools to create a house of geometric shapes.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Fifth graders investigate incline planes and wedges. They identify a variety of incline planes and wedges that are found all around them. Students record their findings using a worksheet.

In this planes worksheet, students solve 5 multiple choice problems. Students determine which planes intersecting create a given line. Students determine which point is coplanar with three other ones.

Pupils distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Pupils predict what geometric shapes they think would be on the battleship; then view a picture and identify the various shapes they see. They take a tour of the battleship Wisconsin they identify various geometric shapes represented by...

Pupils examine works of stained glass in one dimensional art form then adapt it a three dimensional transparent mobile. They create their mobile using patterns of shapes and simple images from computer line art, printed art books or...

In this prealgebra worksheet, 5th graders find the appropriate Cartesian coordinates used to answer the three multiple choice questions.

Students identify and classify solid geometric figures. In this geometry lesson, students bring in objects that look like solid shapes and identify their attributes. Students identify the number of surfaces and faces on each figure.

Students explore geometry by participating in a shape rotation experiment. For this symmetry lesson, students identify the term symmetry and a list of other geometry vocabulary. Students analyze shapes as they are turned 90 degrees and...

Students calculate the perimeter of shapes. In this geometry lesson, students relate properties of polygons to the real world. They find length, midpoint and slope.
