Trick young mathematicians into practicing their basic arithmetic with this extensive collection of fun math games. Whether you're teaching addition, subtraction, multiplication, division, place value, or even fractions, there is a...

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Provide a meaningful context for learning about the division of fractions with this upper-elementary math activity. Presented with a simple, real-world problem, young mathematicians work in small groups to develop visual models...

Positive and negative numbers are everywhere in the world around us. Whether it's charged particles in atoms, a hot air balloon rising and falling in the sky, or a series of bills and checks being delivered in the mail, this...

Math: The only subject where the solution to a problem is seven million matches. Young scholars first complete an assessment task estimating the number of matches they can make from a tree of given dimensions. They then evaluate provided...

Model good modeling practices. Young mathematicians first learn about cross sections and solids of revolution. They then turn their attention to special right triangles and to the Laws of Sine and Cosine.

When complicated algebraic expressions are involved, it is sometimes easier to use a table or graph to model a context. The exercises in this lesson are designed for business applications and require complex algebraic...

How do you create a residual plot? Work as a class and in small groups through the activity in order to learn how to build a residual plot. The activity builds upon previous learning on calculating residuals and serves as a...

Travel back to medieval time where learning is just a stone's throw away! A video introduction shows a trebuchet (catapult-like machine) as it launches a rock into a lake. Learners use their quadratic modeling skills to predict the...

Sixth graders design and draw a model playground to scale. They configure the layout to include a sandbox, slide, baseball field and other equipment. Their design includes adaptations for students with disabilities. Their designs are...
