Probability of Dependent and Independent Events
This Teaching Channel video shows how students can identify and create examples of independent and dependent events. (Common Core Standards Math.7.SP.8a) (5 minutes)
Probability of Independent Events video
This video introduces and explains the concept.
Probability with Dice
Given 2 dice students learn how to find the probability of rolling a specific number in this video. They then use 2 dice in the classroom activities to apply their understanding of probability.

Probability: Playing with Fire
This lesson is designed to help students understand possible outcomes of a probability experiment.
Probability: Tell the Future
A Flocabulary hip-hop song explains and demonstrates ways to express probability in this lesson. To expand their understanding students toss coins and record the results in the classroom activity.

Racing Game with One Die
Students can simulate a race between two cars with the roll of a die and learn about probability through this activity.
Racing Game with Two Dice
By using the applet embedded in this lesson plan, students can simulate a race and learn about probability.
Random Coin Toss
In this interactive from Annenberg students use a tree diagram to record the results of coin tosses to help them understand probability. The classroom activity extends this understanding to compare theoretical and experimental probability.

Replacement and Probability
This lesson will help students learn the difference between sampling with and without replacement.
Spinner
By manipulating a spinner and its pointer students will learn about probability in this activity.
Student Task: Card Game
In this task, students will use probability to make predictions about a card game.
Student Task: Charity Fair
Ann is in charge of a "Lucky Dip" game to raise money for charities. In this task, students use the rules of probability to advise Ann on how to improve the game so that it raises more money.
Student Task: Spinner Bingo
In this task, students must use math to figure out the best way to play a number bingo game.
Students Task: Lottery
In this task, students must use math to decide whether a lottery idea will make money.
The Hunger Games
By analyzing the lottery system used in the novel Hunger Games students will learn about probability. Students then create their own lottery system based on criteria from the novel in the accompanying classroom activity.

Your Odds of Winning Powerball: Probabilities of Compound Events Using Visuals
The sobering odds of winning at Powerball are made clear in this video. Students then create their own models of lotteries to help them understand the probability of compound events. NOTE: You have to create a Free PBS Account to view this web page, but it is easy to do and worth the effort.
