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...

Individuals in your class research the origin of an animal and present their discoveries to the class. The first appearance of the animal and its date of extinction are indicated on a class time line. 

Super detailed, this lesson will educate physical science learners about the flow of electrons. Begin by reviewing potential and kinetic energy with a moving pendulum, and then get them online to observe interactive websites about...

Not all variables are created equal. Discover how variables in computer science are different from variables in math class. Scholars learn to work with variables in computer programming by developing a mental model for how variables...

Gaia Squarci's photo essay, Broken Screen, turns viewers attention to the challenges faced by those with visual impairments. After viewing the images, class members discuss why they believe the photographer structured the album as she did.

The human body maintains homeostasis through the interconnection of multiple systems. Young scientists match these connections and discuss how they relate to each other. They apply their knowledge to solve the mystery of a treasure hunter.

Can you visualize one billionth of a meter? It's not easy to understand the scale of a nanometer. Learners use a hands-on lesson to develop an understanding of the size of a nanometer in comparison to common objects. They walk away with...

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Build teamwork skills while building a bridge. Scholars work together in groups to create a bridge out of 20 straws and tape. There is a minimum span length of 25 centimeters, but otherwise, let creativity run wild.

Approach the lesson from the right angle. A discussion-based lesson leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The lesson is...

It's not just any circle—it's the unit circle. The fourth lesson in the series is an introduction to the famous unit circle. While working through a series of activities, young scholars learn the components of the unit circle and how to...

From a circle to a cycle! The final lesson of a five-part series challenges learners to use points from the unit circle to plot a repeating pattern. The repeating patterns become the graphs of the trigonometric functions. Scholars...

Take a chance with an activity sure to improve your class's skills. An introductory lesson focuses on probability and chance. It shows how probability is always a value between zero and one, i.e., the probability of an event is always...

It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...

A fun, engaging lesson is definitely in the cards for your future. Pupils explore a deck of playing cards in the fifth of six parts in the Statistics and Probability series to learn about its suits and the number of each card type. They...

Flip a coin: heads, use the resource; tails, use the resource. The fourth of six installments of the Statistics & Probability unit looks at coin tosses and probability. The class conducts an experiment and sees that the outcomes of...

Life's not fair, but dice games should be. After playing a two-person game with a pair of dice, scholars investigate the fairness of the game. They consider the number of possible outcomes using the fundamental counting principle and...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

First there was pi and now there's e. A discovery-based lesson plan 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 plan is...

Don't let your class's heart rates rise as you introduce them to differentiation ... an inquiry-based lesson helps them keep it in check! The second lesson in a three-part series asks learners to analyze the rate of change of different...

From derivatives to antiderivatives and back again. Building on the second lesson of the three-part series covering functions, learners explore the concept of an antiderivative. They connect the concept to the graph of the function and...

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

The world is full of patterns. Help learners quantify those patterns with mathematical representations. The first Algebra lesson in a compilation of four uses a series of activities to build the concept of patterns using multiple...
