Friend or stranger? Can there be less than three in a group? The interactive asks learners to prove that for seven people at a party, at least three of them are either mutual friends or mutual strangers. Pupils determine the number of...

There's more to a quilt than just a pretty pattern—there's geometry! Explore angle classification using an artistic approach to show your class that quilt designs are really just intricate geometric patterns. Here, scholars create a...

Keep this resource close by. Given conditions on how close by a child must be to a babysitter, scholars use an interactive to position a picture of the child in relation to the babysitter. Compound inequalities help represent the condition.

Greet this resource like an old friend. An interactive has users investigate the number of handshakes required for a group to greet each member. A set of challenge questions ensures that learners have a solid understanding of the...

Challenge your classes to find the pattern of a double function machine. After recording the outputs of both machines, learners identify the pattern and the corresponding function. Both patterns involve adding/subtracting a constant.

It's okay to get caught with your hand in a virtual cookie jar. Pupils use an interactive to drag cookies from two cookie jars onto a plate. They investigate how an expression representing the number of remaining cookies changes as users...

 A good lesson doesn't just grow on trees! Help your classes understand the concept of a stem-and-leaf plot using an interactive lesson. Learners first create a stem-and-leaf plot from a set of data by dragging the values to the...

What's the best way to dig a ditch? Scholars watch a video that shows the progress of ditch digging from two ends. Using coordinate geometry, they determine whether two ends will eventually connect to form one single ditch or not.

There's no better way to prepare your class for the AP® test format than previous exams. Instructors and scholars use the 2012 AP® Statistics free-response questions to familiarize themselves with the test. Topics covered in the exam...

Preparing for a high-stakes test can be highly nerve-wracking, but understanding the test content and format helps ease the anxiety. The 2009 AP® Statistics free-response questions are available for reference. Several topics under...

Familiarity with the AP® exam is highly beneficial for test-takers. Scholars use the 2010 AP® Statistics free-response questions familiarize themselves with the test content and format. Studies and experiments, linear regression,...

Here's a resource teachers won't want to wash their hands of. Given a task where a full bar of soap is on one side of a balance and 3/4 of a bar of soup and a 3/4-ounce weight is on the other side, young mathematicians must determine the...

Students design models to simulate actual events using various random devices. They estimate the likelihood of a particular outcome using results of simulation. In addition, they simulate the births of three children to a using a coin.

Young scholars conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the...

Students form "companies" of 3-4 students and build bottle rockets for analysis and experiment. This lesson uses NASA's RcketModeler Version 1.2 rocket simulator to evaluate each rocket's flight.

Students participate in an activity to simulate direct variation. In this oil spills on land lesson, students participate in a simulation using toilet paper and vegetable oil to explore the characteristics of direct variation. They...

Twelfth graders determine the probability of two people in their class sharing the same birthday.  In this determining the probability of two people in their class sharing the same birthday problem lesson plan, 12th graders use...

Simulate C-14 decay using M&M and Reese's Pieces candies. In this scatter-plot lesson, students perform an experiment to simulate the half life of C-14. Information is plotted on a scatter-plot. Students answer four comprehension...

Young scholars use their math skills to develop estimates for the population of several animal species native to the Austrailian rainforest. It is a simulation that researchers at the Center for Rainforest Studies in Australia perform...

Students examine simple bank transactions. In this banking lesson, students analyze banking transactions such as deposits, loans, and how they hold reserves. They participate in simulations of the process of clearing a check and the...

Students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

Sixth graders participate in an simulated investment activity. They examine the purpose of different types of investments before they predict which will be the most successful. Finally, they simulate investing $1,000 in stocks, $1,000 in...

Students see how an infectious disease such as AIDS may be quickly transmitted throughout a population. They conduct a simulated transmission of an infectious disease and mathematically determine the number of possible infected individuals.

Students simulate operating a coal mine and calculating the expense of mining operations by choosing a chocolate chip cookie, buying tools to mine the chocolate chips and using paper money to pay for the expense of mining.
