Young scholars create a geometric pattern using mandalas, polygons and symmetry. In this geometry lesson, students analyze the mathematics involved in making the mandalas, including the shapes and symmetry. Young scholars create their...

Students analyze convex polyhedra through hands on methods. In this geometrical shapes lesson, students construct paper models of convex polyhedra and identify the different properties including the number of sides, faces and edges.

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

The illustrations of Ezra Jack Keats in The Snowy Day inspire young artists to examine shapes in illustrations and to use these shapes to create their own watercolor resist painting.

Just how durable could a hollow ball bearing be? Learners model the strength of the walls of a ball bearing as a function of the radius of its cavity. They use their models to make reasonable conclusions about the probability of failure...

Learners consider the rate of filling a cone in the 23rd installment of this lesson series. They analyze the volume of the cone at various heights and discover the rate of filling is not constant. The lesson ends with a...

Students recognize the number prefixes used throughout the English language. They identify the shapes and the prefixes that are associated with them.

High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...

Students explore points, lines and planes as it relates to geometry. In this geometry instructional activity, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Learners problem solve to open a cube to create different shapes. For this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them...

Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Students calculate the volume of different polygons. In this geometry lesson, students identify the relationship between base and height. They calculate the area of each prism and cylinder.

Students respond to Tony Smith's sculpture as art and brainstorm about math concepts inherent in his work. They create a sculpture with polyhedra nets, calculate the cost of covering sculpture in gold, and write an exhibit label for...

Students identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

Help kindergartners develop the academic language they need to master the Common Core standards with this list of math vocabulary. Including the definitions of each term as well as a set of word cards with supporting images and examples,...

What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Venn diagrams are helpful in understanding the idea of a set and using attributes to sort items. This basic plan is an introduction with an added bonus of an applet that can be used to demonstrate the activity. If a classroom of...

What happens to a volume when you scale the dimensions of a rectangular prism? In this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of...

This heady calculus text covers the subjects of differential and integral calculus with rigorous detail, culminating in a chapter of physics and engineering applications. A particular emphasis on classic proof meshes with modern graphs,...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

In this recognizing the importance of recycling worksheet, students complete a cryptograph, read facts about milk and juice cartons, and read about making crafts from trash. Students write 10 answers.
