The Birthday Problem

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

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.

The probability of learning from this instructional activity is high! Learners calculate probabilities as numbers and as decimals. They see how to use a complement to find a probability and even try a simple geometric probability problem.

Statistically, practicing this packet completely helps young mathematicians do well on the test. The packet is adaptable to many grade levels as it includes basic probability and goes up to data analysis with mean, median, and mode. 

Beat the weatherman at his own game with this probability video! Sal shows students how to use probability density functions to predict random occurrences (such as rain). Probability problems - and inclement weather - are no match for...

This lesson is a bit more challenging, but Sal provides an excellent step-by-step explanation. He uses of different colors to help learners follow the process for solving this problem. As he solves one problem, he poses another and...

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...

Multiple worked examples and clear explanation of arithmetic steps really make this presentation on conditional probability stand out.  Specifically, an emphasis on the reasoning behind the calculations helps young statisticians develop...

Get your class on target with probability using an exciting resource. The interactive presents three square dartboards with different target areas, which are combinations of square units. Pupils determine the probabilities of randomly...

The instructor continues to build ratio problem-solving skills, algebraically. The two examples are very involved, but are thoroughly explained with the use of algebraic steps.
