Probability Teacher Resources

On your mark, get set, roll! Explore probability with your class using this series of fun dice games. Beginning with rolling single die, young mathematicians graph the results to learn that each number is equally likely to occur....

If we flip four tails in a row, does that mean all coin flips will be tails? With the law of large numbers, your mathematicians will learn that with more trials their experimental probability will get closer to the theoretical...

In need of a probability resource that has it all? Take a look at a full textbook chapter on teaching and engaging learners in mathematical probability and data analysis. It begins with a teacher preparation section, and then moves into...

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...

Branch out with a tree diagram. A presentation on complex probability explains the process of creating a tree diagram to represent the possible outcomes in a scenario. It then uses the diagram to calculate the probabilities of each of...

Once your learners can calculate experimental and theoretical probability, teach them how to compare their results with this video. Review the difference between each probability and how to set up the ratio from each event. Use the prior...

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. 

Your learners can find a probability, but what happens when there are multiple possibilities? This video introduces the idea of combining probabilities when there are different choices for the outcome. The examples focus on finding the...

Pick a card, any card... and then follow along with this step-by-step presentation as Sam from the Study Jams! crew determines what chance he has of drawing a jack from a deck of cards. This context serves to clearly model how fractions...

Sam bought tickets for a school raffle and wants to know if he has a good chance of winning. Help him find out with this step-by-step presentation on basic probability. Examples clearly model how to find the probability of simple events...

Taking many of the concepts he has covered in the last few videos, including probability, combinations, and conditional probability, Sal uses the example of fair and unfair coins in a bag to show various probability problems. Students...

Sal's back to basketball in this video, which reinforces students' blossoming knowledge of permutations, combinations, and probability by way of free throws. Students who have agonized over a player's failure to shoot consistent free...

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 these...

Flipping a coin and spinning a spinner helps learners reason through the probability of specific events happening in this first of four probability worksheets. Learners predict the outcome when a coin is flipped twenty times and record...

Eight problems get seventh graders selecting the likelihood of certain real-world events occurring. They relate the probabilities in fraction, decimal, and percent form. No answer key is provided, so make sure to create one prior to...

Let's compare the difference between getting lung cancer and then the higher chance of getting lung cancer when you already are a smoker. The video discusses the idea of conditional probability and how a previous event will change the...

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

Here is a turnkey lesson that walks young statisticians through the development and uses of conditional probability. From dice games to surveys, Venn diagrams to frequency tables, the class learns how a given can effect the overall...

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

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...

How likely is it to draw a blue marble? Pupils find the likelihood of events and connect that to the probability of the event. They find the probabilities of simple events and show their probabilities on a scale.

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...

The key to understanding conditional probability is understanding the context of the problem presented. The video presents two questions with a subtle difference between them, then teaches scholars to decipher the difference and...

Odd or even—fifty-fifty chance? �Pupils first conduct an experiment rolling a pair of dice to generate data in a probability lesson. It goes on to introduce mutually exclusive and non-mutually exclusive events, and how to use the...
