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...

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,...

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.

Go round and round to compare theoretical and experimental probabilities. Learners set the number of sectors and the number of spins for a spinner. Then, a table displays the experimental and theoretical probabilities of the spinner for...

Communication is key for a successful parent-teacher relationship, but communication can be difficult when there are thirty-plus families involved. Make your life easier with online communication and an article that details 10...

Introducing ... the Transmographer. Young mathematicians investigate translations, reflections, and rotations. The applet lets users perform transformations on triangles, squares, and parallelograms.

What is the relationship between two variables? Groups work together to gather data on arm spans and height. Using the interactive, learners plot the bivariate data, labeling the axes and the graph. The resource allows scholars to create...

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

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...

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...

Middle schoolers create their own baby pets based on the genes of the two parents.

Pupils create fictional inhabitants to scale for a place called 'Box City'. They develop stories and personalities to go with the created people, share the stories with the class and write a newspaper for their city.

Students watch a "Reading Rainbow" video including the short book reviews that are always shown during each video. They read a book fo their choice and do an oral book report similar to those from Reading Rainbow.

Ninth graders express mathematical properties through creation of advertising jingles.

Ninth graders explore mathematical properties through the use of an advertising jingle. They produce a commercial that is digitized and presented to the class. Students write a jingle that simplifies each property and helps classmates...

Learners use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Eighth graders practice technology skills through the use of a spreadsheet and a discovery lesson focusing upon linear equations. The technology allows for the visual changes to be displayed for different lines of equations.

Students study the idiom as a form of speech. They practice using idioms by developing a Jeopardy game using a provided template.

Learners investigate their personal strengths, skills and aptitudes. They examine and present information about jobs that might meet their qualifications.
