View a throughly humorous, sometimes confusing, and absolutely delightful take on the game theory behind two strategies that help players win at the classic Rock Paper Scissors game. Nothing beats this great resource!

How likely is it that the school cafeteria will serve chicken tomorrow? Discover the concept of probability with the roll of the dice. Pupils evaluate the liklihood of several statments about everyday life. Then, a mathematical...

Your learners will be surprised by the thought-provoking, counterintuitive puzzle presented in this short video that models a fun, fictional situation in which a game is played with two number cubes to decide which of two people wins a...

Chances are good that one will learn a lot about probability. Scholars view an instructional video that covers the basics of probability. They review sample spaces, outcomes, and events, then look at the complement, union, and...

Play some games, develop a law, and then call it a day. Learners first perform a small number of trials for a probability experiment, then predict the result for a larger number of trials. They then compile data from the entire class to...

The more trials scholars perform, the closer they'll likely be to the true value. After designing a probability experiment, young mathematicians conduct the experiment for five different numbers of trials. They then analyze the results,...

The odds will be in your favor that young statisticians will volunteer to participate in this experiment. After watching a short video that is part of the PBS Math at the Core middle school collection, scholars engage in a lottery and...

Spin to win a toy car. A fun activity has pupils use a spinner in which three of the equal sections represent winning a toy car, and the fourth section represents no car. They record the number of wins after certain numbers of spins,...

It's a good thing the resource dropped into your radar. Young mathematicians use an app that randomly drops balls through a Plinko game and into bins. They compare the distribution to that of an ideal binomial distribution.

Build the model right out of the box. A few sample items show teachers how Smarter Balanced assessments may approach Claim 4, modeling and data analysis. Pupils use their skills to create equations or expressions to model the situation...

You have a greater chance of being crushed by a vending machine than winning the Powerball lottery. Part of The Lowdown: Real-World Math series, an engaging video describes how the Powerball works and how to calculate the probability of...

Flip a coin: heads, use the resource; tails, use the resource. The fourth of six installments of the Statistics & Probability unit looks at coin tosses and probability. The class conducts an experiment and sees that the outcomes of...

You're trapped in a dark castle with a pile of gold coins that a wizard will only allow you to leave with if you can solve his riddle. Math learners solve the riddle of the dark coin with the help of an engaging instructional video.

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...

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...

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...

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

How does life evolve? The interactive provides a simulation based on the Game of Life invented by mathematician John Conway. Users can run the applet with the preset rules and settings or adjust them to view whether overpopulation or...

Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...
