Second graders complete an inquiry activity to determine how many combinations they can make using cut-outs of tops and bottoms. In this combinations and organized lists table, 2nd graders work with three colored cut-outs of tops and...

Students use the inequality theorem to solve triangles and their properties. In this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

Students study the story of gold and silver mining in the San Juan region. Through the use of interactive video and the Internet, they will examine the various events occurring at this time. They create a timeline highlighting the major...

Students explore the concept of dividing their money into categories, namely "save," "spend," and "share." They engage in activities that help them explain that money is limited in quantity and must be divided for different purposes.

Students recognize elements of art such as texture, shape line and color.  In this elements of art activity, students create a still life picture with oil pastel or crayons.  Students define elements of art vocabulary....

Eleventh graders explore quadratic equations.  In this Algebra II lesson, 11th graders use Geometer’s Sketchpad to explore the properties of quadratics and the connections with polynomials and linear equations.  The lesson is...

Learners collect data on the weather, graph and analyze it. In this algebra lesson, students interpret maps and are able to better plan their days based on the weather reading. They make predictions based on the type of clouds they see.

Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.

Students determine the cost of a t-shirt using a variety of mathematical operations to solve problems. Then they use a spreadsheet to calculate the cost of lettering a t-shirt and display this information in a graph.

Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

Fourth graders construct mini-ecosystem, pollute the ecosystem, observe, collect, and record data on the effects of these pollutants on their ecosystem, organize data on spreadsheets, create graphs, and design presentations to share with...

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Pupils investigate the properties of a rotation as they use technology (Cabri, Jr.) to observe the relationship between the pre-image and the image formed by the rotation. The lesson provides ample opportunity for learners to conjecture...

Investigate geometric reflections in this geometry lesson. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own. They...

Students play a game called Money Matters using cut out representatives of pennies, nickels, and dimes.

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.
