Converting Metric Lengths into English Lengths

Practice converting metric lengths into British lengths. Feel free to consult the conversion chart and use your calculator if you need to.

Converting Metric Mass Units

Practice converting mass from one metric unit to another. Use your calculator if you need to.

Converting Metric to English Mass

Explore the relationship between the metric and British system. Practice converting metric mass into British mass.

Converting Metric to English Volume

Practice converting metric volume into British volume. Consult the conversion chart and use your calculator if you need to.

Converting Metric Volume

Practice converting volume from one metric unit to another. Use your calculator if you need to.

Counting Raisins

Count the number of raisins in seventeen half-ounce boxes of raisins. Then come up with a solution to determine how many raisins are in Brand X's or Brand Y's box of raisins.

Counting Stairs

Build staircases out of square blocks. Look for patterns and come up with a rule or formula to predict the number of blocks in any staircase.

Creating a Line Plot

Watch as a physical stack of coins is added as a series of dots to a line plot.

Cylinders, Cones, and Spheres

Is there a relationship between the volume of a sphere and the volume of a cylinder of equal diameter and height? What about the volume of the sphere and the cone?

Determining Rotation Symmetry

Explore properties of rotation symmetry. Determine the angle of rotation for different images.

Discover Euler's Theorem

Euler's Theorem states that there is a relationship among faces (F), vertices (V), and edges (E) for every polyhedron. Discover this formula yourself by completing this activity.

The Distance Formula

Plot points on a graph. Use the Pythagorean theorem to calculate the distance between them.

Division with Manipulatives

Area models offer a visual representation of mathematical operations. Use these models to perform multi-digit division.

Drawing a Box Plot

Learn how to represent the Five-Number Summary graphically using a box plot.

Eric the Sheep

One way to solve a complicated problem is to solve a smaller version of the same problem. Without working out the larger problem, predict how many sheep will get shorn before impatient Eric, who is sneaking up in line little by little.

Even Data Sets

How do you find the median for an even numbers of noodles? Learn how in this three-noodle summary of twelve noodles.

Explore & Play with Prisms

Explore the properties of four prisms. Change the direction and speed of each prism's rotation and highlight the numbers of faces, vertices and edges for each one.

Explore & Play with Pyramids

Explore the properties of four pyramids. Change the direction and speed of each pyramid's rotation and highlight the numbers of faces, vertices and edges for each one.

Explore Platonic Solids and Input Values

Observe five platonic solids. Input the number of faces, vertices, edges and the number of faces meeting at each vortex in the table provided.

Exploring Zero and Infinity on a Graph

Explore the number line and its elements through a graphic representation of an equation. Move along the curve of the graph of xy=12 to see how the values change as you vary x or y and consider what happens for negative values of x and y.
