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.

Students will be offered numerous opportunities to further enhance their observational skills as well as the integration of math with their continual exposure to the metric system, measurement, and graphing to represent their data....

Second graders review their knowledge of measurement by making a concept web. They write the measurement words on chart paper and discuss them. They use Kidspiration to make the web using the computer. They add new words as they proceed...

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Students review numbers, number systems and the number operations through the use of online webpages.

Seventh graders explore estimation, measurement, and probability. Students conduct surveys and create charts & graphs. They study the history of chocolate. Students design their own magazine advertisement or create a script for a...

Fifth graders develop a questionnaire to investigate weather in different part of the US. They investigate how weather in one part of the country affects weather in another part. They predict the development of hurricanes.

High schoolers study geometric figures. They use graph paper or Geometer's Sketchpad to construct and decorate geometric shapes, and also create a 3-D polygon using construction paper and a given template.

Using a Smart Board, or a plain ol' white board or chalkboard, the teacher pulls up a grid and demonstrates how squares and rectangles can be divided up into equal parts. The class will get their own graph paper to draw shapes and divide...

Students are introduced to an Underground Weather Stations. In groups, they use the internet to research the weather in different parts of the United States locating each city. To end the lesson, they summarize the information they...

Third graders use ruler and tapes to measure classroom objects. After discussing measurement tools, have students complete sentences stating what they would use to measure various objects. Later in the computer lab, they type their...

While this activity focuses on a study of the Hudson River, it could be used as a template for a discussion of map skills, converting measurements, and plotting a route. The activity includes vocabulary and other resources to make it a...

Students use technology resources for problem solving. They complete math problems or integrated science problems dealing with math concepts using an online calculator.

Eighth graders research and gather information from such sources as Microsoft Encarta, World Wide Web sites, and other sources using computer software to collect data.
