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.

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...

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.

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.

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...

Placement of parentheses is paramount. Scholars adjust the location of parentheses in a numerical expression so its value matches a given value. A slider interactive helps with this task.

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.

In this function worksheet, students evaluate a function given certain characteristics of the function.  The solution is provided by clicking on the "show solution" button.

Bank on your ability to write equivalent expressions. Scholars use an interactive to create expressions using coins. They then convert these to algebraic expressions and figure out how to evaluate them. A game with various difficulty...

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...

We'd all love to have barrels of candy. An interactive shows the steps in evaluating a numerical expression that reflects the cost of buying several different barrels of candy.

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.

Is it safe to take data at its face value? Pupils use the interactive to evaluate a claim that Virgos are more likely to get into a car crash than others. Individuals determine whether another variable may be at play.

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...

Float across the Martian landscape. Using an online game, learners participate in teams to propel their hoverboards in a race across the surface of Mars. By correctly evaluating a numerical expression involving parentheses, individuals...

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,...

When women demanded their right to vote, did the Constitution already protect it? The New Departure Strategy in the women's suffrage movement made this claim through court hearings. Using documents, such as transcripts from Susan B....

Log the values of the derivative of a logarithm. The interactive plots the derivative of the natural logarithm. Learners first determine the derivative of natural logarithm and the general logarithm. Using the formulas for the...

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...

Walking in the park can be good for the body and for mathematics skills. Young scholars use an interactive app to investigate the relationship between squares and square roots using a square with adjustable length. The program also...

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....

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...
