Find the Volume of a Cylinder

Determine the volume of a cylinder. Learn the formula for the volume of a cylinder.

Find the Volume of a Rectangular Prism

Determine the volume of a rectangular cube. Learn the formula for the volume of a cube.

Finding Pentominos

Pentominos are figures made from five squares where each square must touch at least one other square from corner to corner and side to side. How many pentominos can you make?

Finding the Area of Dot-Paper Shapes

Practice two different methods to calculate the area of complex shapes. As you work, think about how you are approaching it, what difficulties you are encountering, and how you would communicate your thinking to others.

Fish Derby

Students have to calculate the optimal number of bass and carp that a pond can support. They determine and graph information about feeding and breeding areas and solve an algebraic equation to get optimal numbers.

Fitting Lines to Data

For a given set of data points, the line that minimizes the sum of the squared errors is the least squares line. Find the least squares line that best represents the height and foot length of 17 people in a scatter plot.

Five Noodle Summary

The Five-Number Summary divides ordered numeric data into four groups with each group having the same number of data values. You will create a five-noodle summary for two different sets of noodles.

Frequency Bar Graphs

Line plots are good for small amounts of data while frequency bar graphs are better for large amounts. Observe how to transition from line plot to frequency bar graph.

From Corner to Corner

Measure the lengths and diagonals of three squares with a ruler. Look over your measurements and try to come up with a rule of thumb for estimating the length of a diagonal if you know the length of a side.

Frosted Cube-Cake

Imagine a cake shaped like a cube that is frosted on all six sides and will be cut into smaller cube-shaped pieces. Make predictions about the number of pieces and the amount of frosting on each piece of cake using the table to check your predictions.

Galton Board

Use the Galton board to validate the Law of Large Numbers. Compare experimental and theoretical results to illustrate the Central Limit Theorem.


Enter commands to direct your drawing tool to create different shapes. Reflect on the relationship between interior, exterior and central angles.

Geometry 3D Shapes

Learn about several three-dimensional geometric shapes and the terminology used to describe them. Learn how to calculate their surface area and volume, and explore their mathematical properties.

Geometry 3D Shapes Assessment: Test Your Skills

Test your knowledge of polyhedra, prisms, pyramids, volume, surface area, Euler’s Theorem and platonic solids. Take this 39-question test, review your correct and incorrect answers, and print out your assessment.

Graphing Lab -- Moose Synthesizer Co.

To price his product and maximize his profit, Albert Moose needs to know all his costs and revenue. Assist Albert with his decision.

Graphing Lab -- Skiing

Michael and friends are planning a skiing weekend. Show them how to afford it.

Group Test Parabola

Graph the sequence and find the equation of the curve. Solve the equation to determine the value of the 100th term of the sequence.

Guess My Button

Practice classification/pattern recognition skills by guessing which button out of sixteen the computer has chosen. Go through a series of online questions about the buttons that differ in size, color, shape and number of holes to determine the answer.

Guess My Rule

Someone makes up a mystery algorithm and keeps it secret. With the help of the function machine, try to discover the algorithm with as few guesses as possible.


Review the transitions between various graphical representations of data and discuss the advantages of a histogram have over a stem and leaf plot. Also consider the disadvantages of a histogram.
