"Probably Pistachio" by Stuart J. Murphy

Cultivate the tree of knowledge using diagrams with two stages. Pupils create small tree diagrams to determine the sample space in compound probability problems. The lesson uses only two decision points to introduce tree diagrams. 

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

Use tree diagrams with multiple branches to calculate the probabilities of compound events. Pupils use tree diagrams to find the sample space for probability problems and use them to determine the probability of compound events in the...

If you keep rolling a die, you'll roll a five exactly one-sixth of the time—right? A probability lesson prompts young mathematicians to roll a die 100 times and use the data to calculate empirical probabilities. They then compare...

Learners make predictions and draw conclusions from given information as they learn the meaning of probability in this vocabulary-rich, integrated activity that presents a variety of teaching strategies to motivate and reach...

Roll the dice with this multimedia math lesson on probability. After first viewing a series of three short videos explaining probability, independent events, and dependent events, young mathematicians complete a set...

Expanding the "unfair coin" problem from the previous video, Sal discusses the concept of dependent probability. Both his annotations and his trusty calculator are essential elements in solving (and understanding) this problem.

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...

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...
