Identifying types of angles meets real-world application in an excellent, hands-on geometry activity. Learners use pipe cleaners and a visual model to independently discover the acute, right, or obtuse angles in their classroom,...

A home improvement plan can help adult learners preparation for the GED exam. They review vocabulary, prepare diagrams, complete a worksheet, calculate perimeters and analyze how to approach a story problem. They identify many geometry...

How do you find the measure of an arc? Learners first review relationships between central and inscribed angles. They then investigate the relationship between these angles and their intercepted arcs to extend the Inscribed Angle Theorem...

Youngsters develop mathematical vocabulary with this worksheet. First, give youngsters time to identify their vocabulary words in the picture provided. Then, as a group, practice saying the vocabulary words aloud. Finally, have learners...

Middle and high schoolers calculate the volume of cylinders. In this geometry lesson, learners differentiate between rectangular prisms and cylinders. They use the correct formula to solve for each solid.

What does completing the square have to do with circles? Math pupils use completing the square and other algebraic techniques to rewrite equations of circles in center-radius form. They then analyze equations of the form x^2 + y^2 + Ax +...

Students prepare to take the GED by reviewing basic math concepts. In this geometry lesson, students review vocabularies such as formula, perimeter, circumference and other important geometric terms. They convert between the English and...

Students identify units of measurement. In this measurement lesson, students predict the length and width of their hands and feet. Students discuss their findings and if their predictions were correct.

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

First graders explore geometry by completing a worksheet in class. In this non-standard measurement unit lesson plan, 1st graders discuss different techniques for measuring items without the use of a ruler. Students read several short...

Students calculate the volume and surface area of each shape. In this geometry lesson, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Elementary school learners investigate the attributes of a square. They discover that squares are polygons and examine squares found in everyday life. They concentrate on connecting the word, square, with the shape. As an...

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Students explore geometry in Navajo rugs. In this shape art lesson, students create a Navajo rug design using triangles and squares. Students investigate designs on the Internet and then create an original design.

Students identify the different properties of polygons. In this geometry lesson plan, students differentiate between polygons and non-polygons. They review important vocabulary to help them understand the properties of polygons.

Sixth graders explore geometric figures. In this geometry lesson, 6th graders manipulate properties and relationships of geometric figures to identify objects on the coordinate planes and describe where figures sit on the planes.

Navajo art incorporates many fascinating shapes and designs. In this shapes lesson plan, students explore how shapes may be combined to create art and architecture. They also discover shapes in the world around them.

Fifth graders classify triangles. In this triangle instructional activity, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students consider an individual habit and its cost. They study ratios and proportions, and use that knowledge to calculate the cost of a habit over extended periods of time. write a detailed comparison of the costs.

First graders explore geometric shapes. In this math lesson, 1st graders sort shapes into groups and discuss the characteristics of the shapes. Students build geometric shapes using toothpicks and marshmallows.
