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. 

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....

Connect ratios, probability, and combination outcomes with a challenging activity idea. It guides your learners through probability of an event as fractions or ratios, on a number line, and with correct vocabulary. The class will be...

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 activity on probability. After first viewing a series of three short videos explaining probability, independent events, and dependent events, young mathematicians complete a set...

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...

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

Young scholars investigate probability. They will define probability as the likelihood of an event occurring. Then, they determine the probability of sitting in a particular seat on a plane. They also set up ratios of various seating...

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...

Here is a very clever way of teaching young mathematicians the concept of probability. A spinner is made that has two outcomes, yes and no. A chart is made that has two columns that are labeled Correct and Incorrect. The teacher asks a...

Your statisticians examine the characteristics of conditional probability and the probability of simultaneous independent events. They perform computer activities to find probabilities for simple compound events. They examine the...

Students investigate the area of squares and circles. For this geometry lesson, students calculate the area and probability of simple events. They work on a laptop using Safari.

The comprehensive, overall purpose in teaching probability is to help students draw conclusions about the characteristics of a large group given a small sample taken from the group. Probability is related to predicting the chance of a...

Classes explore different scenarios using manipulatives to learn about the difference between independent and dependent probability. Learners experiment with colored chips to model the two types of probabilities. To test their...

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Being a statistician means never having to say you're certain! Learners develop two-way frequency tables and calculate conditional and independent probabilities. They understand probability as a method of making a prediction. 

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...
