How can you formally assess understanding of circle concepts? Pupils take a mid-module assessment containing five questions, each with multiple parts.

The lessons are complete. Learners take an end-of-module assessment in the last installment of a 23-part module. Questions contain multiple parts, each assessing different aspects of the module.

Here is a lesson that takes an interesting approach to analyzing data using box and whisker plots.  By using an applet that dynamically generates Venn diagrams, the class forms a strategy/algorithm for guessing the rule that fits...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the...

How have educational standards evolved? Educators of adults examine expectations in the 10th workshop out of 15 to better determine how standards have grown. Participants respond to a variety of sample questions to determine how they...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

Help your class look for patterns as they create their own arithmetic and geometric sequences. Engage learners with an introductory discussion on sequences and use the applet to let them explore how sequences are formed. Teachers might...

Use this series of activities to introduce learners to graphing functions. They graph both linear and quadratic equations by hand and with a Graph Sketcher Tool. Several imbedded links and handouts are included in the lesson.

Chunking information helps you remember that information longer. A hands-on activity tests this theory by having learners collect and analyze their own data. Following their conclusions, they conduct randomization simulations to...

Collaborative groups examine the importance of energy resources on quality of life by researching different energy sources and alternative energy sources through data analysis. They make a comparison of different countries and cultures,...

What can math say about natural phenomena? The fifth STEM lesson in this project-based learning series asks collaborative groups to choose a phenomenon of interest and design an experiment to simulate the phenomenon. After collecting...

Allow your classes to research what interests them. An engaging STEM lesson, the fourth in the series of six, asks individuals to choose a topic of interest and analyze the data through regression models. The regression equations allow...

How much is a million? This unit has a set of lessons investigating large numbers on the order of millions and billions. A culminating project has groups creating a slideshow and poster about large numbers found in the school and/or...

Students explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography activity, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

This interactive website provides a variety of lesson plans according to which standards you are applying and which textbook you use. Introduce functions to your class by having them construct single operation machines and create...

Practice factoring numbers by using graph paper, manipulatives and computer applets.

Fourth graders are introduced to arithmetic and geometric sequences. In this mathematics lesson, 4th graders produce a variety of sequences by varying the starting number, multiplier, and the add-on number.

Students are introduced to the basic ideas needed for understanding linear functions.

Pupils explore the concept of linear functions. In this linear functions instructional activity, students translate linear functions from tables to graphs to equations. Pupils use an applet to write a function rule for a linear...

Students explore the concept of functions. In this function lesson, students determine if the graph is a function by using the vertical line test. Students use an applet to explore the vertical line test on a variety of graphs.

Young scholars investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.
