Challenge young engineers to design a one-bedroom scale house that would collect and maintain as much heat as possible. Special constraints must be adhered to, but creativity is also allowed. Diagrams and background information are...

But it's just a game! Learners play a game to learn basic concepts of statistical hypothesis testing. After using the digital-game module, pupils develop their own statistical hypotheses and test them.

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...

Open your imagination to make algebra-inspired creations. An interactive lesson has scholars graph images from a set of parameters. Users can practice minimum values, maximum values, and scale as well as key features.

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...

Young mathematicians learn how to solve problems involving stratified sampling. They review concepts of sampling and proportionality by watching a video and then they complete a worksheet of questions on this topic.

A series of step-by-step worked problems demonstrating how to take a set of data and produce the variance and standard. Hints are provided along the way and the final measures are shown for the user to check.

A demonstration of how to find the standard deviation of a set of data. Several examples and a practice test are offered.
