Serve up a slice of math for Pi Day! A combination of fun, hands-on lessons and helpful worksheets encourage learners to practice finding the radius, diameter, and circumference of different circles.

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

The topic of trigonometric ratios is often covered with loads of rote memorization baked into the activity. This activity set, however, leans more on using similar triangles and discovery learning to help young geometers develop a deeper...

Over the corse of a month, small groups will monitor the price of a specific energy commodity and analyze it in relation to global and domestic events. They play a trade simulation game and create infographics showing what they've...

Learners honor mathematicians who have contributed important discoveries throughout history by researching and creating a report about a famous mathematician and their contributions to the history of mathematics. Pairs of learners...

Practice important angle vocabulary using an interactive lesson. As learners manipulate vertical angles, they watch the supplementary and congruent angles adjust. Questions pertaining to vocabulary and measurements follow their exploration.

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...

First there was pi and now there's e. A discovery-based lesson helps learners find a pattern in compound interest as the compounding period changes. Their investigation results in the discovery of the number e. The lesson is the first in...

Bringing together the young artists and the young organizers in your class, this lesson takes that popular topic of tessellations and gives it algebraic roots. After covering a few basic properties and definitions, learners attack the...

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

Learning to create and maintain a budget is an important life skill. Guide individuals in the discovery of their spending habits and how to track them. They then use what they learned to create a budget and make decisions on where they...

If your youngsters are new to numbers, here are several interactive strategies to get them thinking about even and odd numbers. For example, they can count the number of desks, people, etc. in the room and determine if it is even or odd....

Be ready mathematicians of every level. This lesson leads to the discovery of the zero product property and provides challenges for early finishers along the way. At conclusion, pupils understand the process of using the zero product...

Not all linear functions are linear transformations, only those that go through the origin. The third lesson plan in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at...

Explore angle relationships created by parallel lines and transversals. The 13th lesson of 18 prompts scholars use transparency paper to discover angle relationships related to transversals. Learners find out that these angles pairs are...

Sixth graders examine the Lewis and Clark Expedition. For this plant discovery lesson, 6th graders put in chronological order the plant discoveries of Lewis and Clark. Students understand the characteristics of leaves and find the area...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson plan series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Build a strong understanding of simplified rational expression with your classes. An interactive lesson helps scholars discover the equality between the original expression and the simplified expression. Questions help individuals focus...
