This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.  

A wind turbine is essentially just a giant pinwheel, right? Individuals first create pinwheels from paper, pins, and pencils. In groups, they model a wind farm along a coast and then test out their designs using an electric fan.

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

In this right or left learning exercise, learners study a graph with colored shapes on it, then choose either right or left to tell where each shape is located.

Students create models to represent both linear and quadratic equations.  In this algebra lesson, students collect data from the real world and analyze it. They graph and differentiate between the two types.

This resource guides young geometers to create new polygons from others of equal area, compare an image to its reflection and find errors, conduct repeated reflections, map translations, and determine center of rotation. No solutions are...

Eighth graders explore the Pythagorean Theorem. They use Geometer's Sketchpad and explore features of various figures. Students use the software to build a figure using the given measurements.

Students explore how bees make honey and why the hexagon is the best basic pattern for the honeycomb through the use of a video and hands-on activities with honeycombs and geometric shapes.

Middle schoolers complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a...

Five pages for geometry practice relating to symmetry provide mathematicians with exercises on transformations and symmetry, properties of isometries, compositions of transformations, tessellations with regular polygons, and other...

Skywriters is an introductory challenge games from ropes course material. It focuses on communnication, team cooperation, trust, and problem solving. There is a link to several more challenge games.

Students listen carefully and put pieces together following the teacher's instructions. They point to the different shapes and sizes as they are being called out and count the number of items they have in front of them. They decorate...

Middle and high schoolers explore the concept of proving the Pythagorean Theorem. They research proofs of the Pythagorean Theorem. Pupils create posters of proofs, and research Greek mathematicians.

Students explore volume and surface area. In this math lesson, students fill boxes with cubes to identify the volume of the boxes. Students discuss area.

Learners explore the concept of polygons on a two-dimensional plane. They identify polygons in everyday life and draw different polygons according to their classification. Using a geoboard and geobands, they consrtuct polygons and even...

Students engage in a lesson that is about birds while taking part in a variety of activities that are like the following. They play a game that is used for increasing memory while using bird pictures. Students also create a collage with...

Learners calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Students, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.

Explore the world of shapes! After free tangram exploration and pair share time, learners describe various patterns and shapes in both the natural and designed world. They investigate the use of tangrams to create patterns and shapes.

Young scholars observe the colors found in the flame of a burning candle and examine the basic concepts of matter and energy. Students apply this information to the color's of starts and the temperature of the stars photosphere. Young...

First graders read the book, RAINBOW FISH and view a few pictures of different types of fish. They discuss putting certain shapes together make up objects and talk about and demonstrate straight and wavy lines, thick and thin lines....

What does popcorn have to do with math?  Seventh grade mathematicians are provided an opportunity to develop a conceptual understanding of the formula for volume and to use it as a tool to solve problems. The lesson begins with a...

What is the sharecropping system? What role did it play in the post-Civil War economy of the South? Who were the sharecroppers? Who employed them? How were they paid? To answer these questions, kids examine a series of sharecropper...
