Students calculate the radius of the earth. They use the method and data suggested by Eratosthenes. They investigate the interrelationships among mass, distance, force, and time through experimental processes.

Young scholars investigate important women in Mathematics.  For this middle or high school mathematics lesson, students research the accomplishments of women that played an important role in the history of mathematics or women...

Learners examine the definition of inflation and its impact through history. They read and discuss online text, discuss examples of inflation, calculate the prices of various items for different years using an inflation rate of 3%, and...

Show your class how people calculated complex math problems in the old days. Scholars take a trip back to the days without calculators in the 15th installment of a 35-part module. They use logarithms to determine products of numbers and...

Everything you wanted to know about calculus—and more! The resource is a complete Calculus textbook with explanations, examples, and practice problems. 

This textbook takes the learner from the basic definition of slope through derivatives, integrals, and vector multivariable calculus. Each section is composed primarily of examples, with theoretical introductions and explanations in...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Students examine the concepts of symmetry, rotations, reflections, translation, dialations, and tessellations and apply them to indigenous art. They also do Internet research and create artwork (painting, pottery, computer graphic design).

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Students solve problems using the pythagorean theorem. They use critical thinking skills in order to use a systematic process to solve the problem. Upon solving each problem the uniqueness of the lesson is asking students to give an...

The Golden Ratio. The Divine Proportion. Yup. It's math and art blended into one colorful activity. Young artists combine colored tissue paper circles and parts of circles to create geometric patterns. As a bonus, kids get to figure out...

Ninth graders, in groups, search for and locate resources on a chosen famous mathematician. Enough information needs to be gathered to examine the mathematician's life and his/her contributions to the field of mathematics.

Students discover how units of measurement help people to categorize objects. In this measurement lesson, students discuss various units of measurement, use creativity to invent new possible units of measure, and learn the history of...

Tenth graders investigate the early history of geometry. In this geometry activity, 10th graders investigate translations, rotations, and reflections. They also solve problems with line of symmetry and rotational symmetry while reviewing...

Learners develop an understanding of measurable attributes of circles; develop a formula to determine the circumference of circles. They approximate the value of pi.

Second graders take a field trip to a nearby church or other historical building and examine it from a mathematical perspective. In groups, they calculate the seating capacity, describe the window patterns, differentiate types of...

Scholars view the video, "Donald Duck in Mathmagic Land," and discuss examples in nature which have proportions of the golden ratio. They measure and record different body lengths from a worksheet and convert the ratios to equivalent...

Here is a set of lessons that explore conics in a number of different ways. Starting with modeling how a conic is produced by the way a plane cuts the cone, to solving complex word problems, algebra learners progress through a series of...

Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

Use the given tasks and detailed teacher's commentary to introduce your 8th graders to the Pythagorean theorem and its converse. Embedded links to information about Egyptian geometry make your presentation interesting. Consider...

Can survival rates on the Titanic be explained by the "women and children first" policy or did rescue procedures favor the wealthy? Use actual historical data to explore conditional probability and independent events with your class....

Students use the internet to research the history of Fair Haven, Connecticut. In groups, they are introduced to the socio-economic developments and how the area has grown over time. They work together to create their own bridge design...

Students explore the history of cryptography. They assess function notation and transformation, matrix operations, and the fundamentals of modular arithmetic. Using graphing calculators, students develop their own encryption schemes.

More people, more garbage! Young environmentalists graph population growth against the amount of garbage generated per year and find a linear model that best fits the data. This is an older resource that could benefit from more recent...
