Grade Level(s): 3-5
2.Next ask them how could they make a better guess of which type of coin you would pull out of your pocket. They should note that if they know what coins you have in your pocket, then it is sometimes easier to guess which type you would select. For instance, if you only had pennies in your pocket, then you would definitely pull out a penny, and definitely not pull out a quarter.
3.Next, illustrate to the class how you can use this example of coins in a pocket to show probability. For instance, if you have a pocket with 1 nickel and 4 pennies, then the chance or probability that you would select a penny is 4 out of 5. The probability you would select a nickel is just 1 out of 5.
4.Supply your students with a worksheet like the sample listed under Materials(online). For each pocket of coins, have them answer the questions:
- What is the probability of reaching into the pocket and pulling out a nickel?
- What is the probability of reaching into the pocket and pulling out a dime?
- What is the chance that you can reach into this pocket and get a penny?
- What is the chance that you can reach into this pocket and get a quarter?
