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...

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation....

Something for young mathematicians to remember: the sum of any two sides must be greater than the third. Class members investigates the Triangle Inequality Theorem to find the relationship between the sides of a triangle. At the...

It's just not enough to know that something is true. Part of a MVP Geometry unit teaches young mathematicians how to write flow proofs and two-column proofs for conjectures involving lines, angles, and triangles.

Learners discuss personal finance and create personal budgets. They discuss the importance of managing their money and how money management skills impact their future. Note: This lesson is intended for use with a SMART Board and...

Learners engage in six activities to lead them through the process of conducting a thorough analysis of data. Pupils work with calculating standard deviations and z-scores, finding the area under a normal curve, and sampling...

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

Make the connection between the distance formula and the equation of a circle. The teacher presents a lesson on how to use the distance formula to derive the equation of the circle. Pupils transform circles on the coordinate plane and...

Learners engage in science, math, and language activities as they do research on the components of the solar system. The class begins with some anticipatory activities and discussions before it is divided into small groups to conduct...

Seeing is believing. Given several bivariate data sets, learners make scatter plots using the online SeeIt program to visualize the correlation. To get a more complete picture of the topic, they research their own data set and perform an...

Assign an interactive poster activity to assess your class's knowledge and skill concerning data analysis. The teacher reference provides solid questions to ask individuals or groups as they complete their posters.

Second graders conduct a class census to measure diversity.

Learners explore the concept of time. Through discussion and artistic projects, they define time in their own words and tell how it is used to represent the seasons. Students draw a picture to portray time as it elapses during the...

Students monitor current events using on-line and traditional resources. They explore issues such as what trends they see developing in specific news issues over time and how different news stories might be interrelated.

Students study the buying and selling market and how prices are determined for an agricultural product. In this competitive market lesson, students study how prices are determined in a market by studying the forces of supply and demand....

Young meteorologists examine the four main types of weather fronts and how they appear on a weather map. Participants learn about the difference between the types of weather fronts along with their distinguishing features. A...

Weather — there's more to it than meets the eye of the storm. With this resource young meteorologists learn about the basics of weather, including information about the factors that influence the weather, common weather vocabulary,...

Fourth graders read and discuss the sun and the energy we use on Earth from the sun. In this sun lesson plan, 4th graders discuss the solar system, planets, and answer short answer questions.

Learners are shown the very basics of navigation. The concepts of relative and absolute location, latitude, longitude and cardinal directions are discussed, as well as the use and principles of a map and compass.
