Fill your mind as you fill virtual water bottles. Pupils use an interactive to find the amount of water that can fit in given containers. Writing and evaluating an algebraic expression helps with this task.

A series of interactive exercises provide users with the ammunition they need to detect logical fallacies and defend themselves against persuasion. Learners read about 11 types of logical fallacies and identify the type used in sample...

Limits are made easy through graphs and tables. An easy-to-use interactive lets users change a function on a coordinate plane. They relate graphs and tables to the limit at a specific value.

High school juniors learn how to construct a strong argument by crafting a claim and using neutral language backed by evidence from reliable sources. To do so, they learn to evaluate sources and evidence to support claims. They then...

Push an engaging resource to the limit. The interactive allows learners to find a limit on quadratic functions graphically. Using sliders, pupils set the x-value for the limit and to move values from the left and right toward the limit.

Is Sherlock Holmes an inductivist or a deductivist? Users of this interactive to distinguish between inductive and deductive reasoning. They consider in various situations whether it is better to list evidence and then introduce a claim...

Although popular culture tells the story of the American West simplistically, its reality is far more complex. Native American tribes—while already on the land—didn't have the same interests, and conflicts between white settlers and...

Help your class develop an understanding of sigma notation. Pupils match the sigma notation with the sums. Using the expanded sums, learners evaluate the summations. The scholars move on to prove a property of sums.

Was the Civil War fought only due to slavery? Using an interactive web tool, scholars investigate the four main causes of the Civil War. Gathering evidence and data to support their claims, they present a final statistical breakdown...

Even the most inspiring documents in American history had to go through a few drafts before they were ready for publication. Reinforce the importance of the writing process, as well as the collaborative nature of democracy, with an...

Discontinuities in the graph? No worries. Pupils investigate the limit of a function given graphically using an interactive. The graph has removable and jump discontinuities.

Needlework isn't just for home decor; it can also help record family history. Academics analyze a needlework sampler to understand how they were used to record marriages and births. The activity includes a series of written questions,...

It's okay to get caught with your hand in a virtual cookie jar. Pupils use an interactive to drag cookies from two cookie jars onto a plate. They investigate how an expression representing the number of remaining cookies changes as users...

How can you determine the rate of change on a curve? Pupils use the interactive to discover what happens with the average rate of change as the point move closer to the other. Using the definition of the derivative, learners find that it...

An interactive challenges mathematicians to add mixed fractions with unlike denominators. Five questions—fill-in-the-blank and multiple-choice—build from one to the next leading the way to an open discussion about denominators and...

Sometimes playing games in class isn't a bad thing. Science sleuths evaluate and calculate pH and pOH with an online resource. They then manipulate concentration information and relate it during a series of puzzles.

In this online interactive literature worksheet, learners respond to 9 short answer and essay questions about C.S. Lewis's The Lion, the Witch, and the Wardrobe. Students may check some of their answers online.

Shopping for a resource on writing algebraic expressions? Look no further. Pupils use an interactive to drag shirts and pants out of a shopping bag. They create and evaluate an expression to represent the cost of the clothes.

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Time to put those mental math strategies into play with an interactive that has learners thinking about how many candies three friends get altogether.

Rational functions become less mysterious when you know about limits. Individuals use an interactive to move a rational function on a coordinate plane and to investigate function values for certain x-values. They see how the limit...

Chase a periodic moving limit. Learners graphically determine the limit of the tangent function at different input values. Using sliders, pupils find out whether the tangent function approaches the same value from the left and the right....
