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...

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...

Exactly how fair are the board games children grow up playing? Young mathematicians investigate this questions as they work their way through this five-lesson series on basic probability. 

Run, gingerbread men! During the board game, four gingerbread men race to discover which one finishes first. Scholars take note of the game's results using a tally chart and bar graph for all to observe the frequency of the winning...

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...

Who said things were fair? The unit introduces probability and its connection to fairness. The class interacts with activities of chance and plays games to relate them to fairness. Groups design a fair game and develop a presentation....

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

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...

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...

Check out this detailed lesson plan on conditional probability!  Learners work individually and also collaboratively to analyze the fairness of a game and justify their reasoning. it includes detailed notes and many helpful...

To foul or not to foul, that is the basketball question. High schoolers look at the probability that fouling out a player and allowing free throws yields a better outcome than allowing the original shot. The resource provides a...

First graders use probability terminology to describe all possible outcomes of certain events. In this probability lesson, 1st graders use counters to create a pretend "purse" of objects. Students create their own probability...

Life's not fair, but dice games should be. After playing a two-person game with a pair of dice, scholars investigate the fairness of the game. They consider the number of possible outcomes using the fundamental counting principle and...

A fun, engaging lesson is definitely in the cards for your future. Pupils explore a deck of playing cards in the fifth of six parts in the Statistics and Probability series to learn about its suits and the number of each card type. They...

Flip a coin: heads, use the resource; tails, use the resource. The fourth of six installments of the Statistics & Probability unit looks at coin tosses and probability. The class conducts an experiment and sees that the outcomes of...

Elementary schoolers find out which month has the most class birthdays (mode) and which birthday represents the middle point of all the birthdays (median). They gather and organize data to find one number that fairly represents the whole...

Students study the concept of probability. In this probability lesson plan, students define probability and visit an interactive spinner website to learn about theoretical and experimental probability. Students use pennies and work in...

How do we determine how much information to include and what can be left out? By playing a game of 20 questions, the class generates the best strategies for finding a number. They then move on to guessing the next letter in a short...

Turn students into detectives as they decipher encrypted messages.  Introduce your class to modular arithmetic and have a little fun encrypting and decoding secret messages. The activity does not hit many content standards, but...

Explore the difference between stochastic and deterministic modeling through programming. First have the class write algorithms for relatively simple tasks using pseudocode. Use the Python 2.7 program app to simulate Mendel's Pea Pod...

Learners complete an on line, teacher created, webquest to study the origin of probability, theoretical and simulated probability; computing the probability of two independent events; and mutually exclusive events. They make a Venn...

Students investigate the concept of even change by participating in a coin flip activity. They research using the Internet to investigate the chance of giving birth to a boy.

Students predict results, design a model, and carry out trials to determine probability based on their experimentation.
