Students study West Virginia quilts. In this mathematics activity, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Students study the law of sine and cosine. For this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.

This lesson entails the viewing of two videos to get an overview of force and its application. The lesson covers how vectors use force in real-world situations.

Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...

Students work with circles, angles and estimating angles in the night sky. In this circles and angles lesson plan, students practice measuring a degree using the circumference of a circle and apply the degree to determine a way to use...

After being introduced to the basic trigonometry functions, students calculate the height of school landmarks. They experiment with different angles to find the correct height.

Students create perpendicular bisectors. In this geometry instructional activity,students use a straight edge and protractor to create a perpendicular bisector. They graph line on the TI and analyze it.

In this geometry worksheet, 10th graders solve problems involving the perpendicular bisectors and angle bisectors of a triangle and their points of concurrency.  The one page worksheet contains sixteen questions.  Answers...

For this geometry worksheet, young mathematicians divide a parallelogram into four, by choosing points along a diagonal.  Students calculate the area of each parallelogram and look for any patterns that may emerge.  The...

Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...

Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...

Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

Students examine the correlation between art and math. Using their computers, students construct and measure angles. Students identify the properties of angles and polygons. They engage in the Angles program on their Palm and use the...

Students explore the concept of triangle inequalities.  In this triangle inequality instructional activity, students cut spaghetti noodles into given lengths.  Students use the noodles to complete a worksheet about triangle...

Learners discover and practice how to calculate the circumference of the Earth. They measure the length of their shadows and use the distance they are away from the equator to complete the calculations. They discuss winter or summer...

Young scholars bisect angles and segments using a mira. They measure the original angles and segments and the angles and segments formed by bisecting to better see the relationship between them.

Collaborative groups work with geometry manipulatives to investigate conjectures about angles. They create a graphic organizer to use in summarizing relationships among angles in intersecting, perpendicular and parallel lines cut by a...

Students rewrite word problems and solve using math. In this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...

Students determine the age of a star cluster by observing, measuring, and plotting astronomical data. They examine the Jewe lbox cluster, located within the southern constellation Crux and determine its age.

Sixth graders engage in problem solving, communicating, reasoning, and connecting to represent and solve problems, using geometric models.

Students explore economics by reading classic literature with their classmates. In this farm production lesson, students read the famous story Little House in the Big Woods by Laura Ingalls Wilder. Students complete handouts based upon...
