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.

Fulfilling a dream requires a lot of hard work. A study guide for the novel A Single Shard shares the dream of a young Korean orphan. As readers work through the guide, they answer comprehension questions about Tree-ear and the...

Let's work together! Using the collaborative resource, scholars work in triads to begin section two of their storyboards about Philo Farnsworth, the inventor of the television. They then practice using linking words and phrases to...

How did the television change people's lives? Learners consider the question as they complete their storyboards about the invention of the TV, adding visual elements along the way. Then, they participate in a peer review to offer and...

Let's get graphic. Serving as the final performance task of the unit, scholars complete their graphic novelettes and design covers based on their sketches. Finally, they present their hard work to classmates. 

Eyes on the finish line. Serving as the first part of the end of unit assessment, learners answer questions based on a text about how to write a graphic novel. Using what they've learned, they then create a storyboard about the invention...

Stay on target. The class reviews the learning targets for the unit and the end of unit assessment. Scholars then begin working on part one of the assessment answering how Canada's natural resources meet the needs of the people and how...

Students evaluate the sustainability of an enterprise based on how well it contributes.  In this sustainable agriculture lesson students build skills as they work together by using the Internet to research and develop their own...

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Tenth graders share perspectives on war with Iraq with students from various countries, and write position papers expressing specific stance on issues.

Students examine the opposition of the US Senate to Woodrow Wilson's idea of a League of Nations. They discuss the central ideas involved in the debate over the League.

Young scholars identify at least one country where the Spanish language is spoken, describe similarities and differences between Spanish, Mexican, and Puerto Rican families, and practice speaking the Spanish words for several family...

Fourth graders participate in a stock investment activity in which they research stocks to place in an imaginary portfolio. They invest $10,000 in a variety of stocks and track their progress using the Internet or newspapers.
