Introduction to the Concept of Probability

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...

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. 

Class members are introduced to probability using terms such as impossible, unlikely, likely, and certain. Numbers between zero and one are associated with the descriptions of probability. Pupils find the likelihood of chance experiments...

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...

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 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,...

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...

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...

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...

Roll the dice with this activity and teach young mathematicians about probability. Record outcomes for rolling two number cubes in order to determine what is most likely to happen. Graph the data and investigate patterns in the results,...
