Connect the points to create a function. Using points given by the applet, pupils try to connect them to create a line that would pass the vertical line test. The resource keeps track of the number of sets the learner is able to identify...

What's behind door number one? A fun resource lets learners simulate the classic Monty Hall probability problem. Pupils choose a door, and after they select a losing door, they decide whether to switch or stay. Using their decisions, the...

Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...

Are your young mathematicians having a hard time making heads or tails of probabilities? It's no toss up—here is a resource that's sure to straighten them out! Learners run the interactive to toss a coin a different number of times....

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

Find the box with two green balls. The applet uses six balls, three green and three red, and hides them in three boxes. Pupils choose a box and click on it to reveal the color of balls inside. Using the chosen box, the simulation keeps...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

You'll have no regrets when you use the perfect lesson to teach regression! An interactive resource has individuals manipulate the slope and y-intercept of a line to match a set of data. Learners practice data sets with both positive and...

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

If you've ever looked at the US immigration system, you know that it is complex and a source of controversy. An insightful lesson plan encourages learners to conduct their own analyses of the US immigration system by asking them to...

The Election of 1912: an election with four competitive opponents. Pupils get to know the candidates with informative reading passages that provide context to the election. Then, the class engages in a debate and answers questions as one...

What is satire, and what are its characteristics? A handy handout provides young satirists with all the information they need to analyze a satire or to craft their own.

A free press is entitled to its opinions. While the news pages report the facts of events, editorial pages feature writers' and cartoonists' opinions about events to either directly or indirectly persuade. Introduce viewers to the art of...

Have you ever seen a movie about the romance of the American West with its buffalo, horses, cowboys, and endless frontier? The 13th installment of a 22-part series on American history presents the myths associated with the American West....

Was Puritan society governed as more of a theocracy or democracy? After comparing and contrasting a series of primary source documents, middle and high schoolers form small groups and debate the question.

Sex sells, or in this case, sex cells allow reproduction to occur. Scholars view a presentation and animation as well as complete a worksheet on meiosis and gamete production. They observe every stage and learn about the function and...

All life requires energy ... and the connection between energy and plant life typically requires photosynthesis. Scholars explore photosynthesis in depth from ATP/ADP through the Calvin cycle. A helpful presentation highlights concepts...
