Let’s see how many coin combinations we can pick that would equal 25¢. What is one way to make 25¢?”
Most likely first answer will be to use one quarter. Tell student(s) this is correct.
Have a student volunteer with a “quarter sign” come to the front.
NOTE: For younger students, you can end with just this example. Be sure to skip subsequent slides.
NOTE: For older students, ask for other combinations of coins that make 25¢
Examples for students with more math experience:
2 dimes and a nickel (fewest coins)
5 nickels
4 nickels and 5 pennies (most coins)
With each combination, bring students with corresponding signs up to the front of class and count to 25 each time as you total the coins.
NOTE: If you decide to demonstrate multiple coin combinations using volunteers, be sure to make up and bring enough of each coin sign.
For example: twenty-five cents in pennies will require 25 copies of the penny sign, distributed to 25 volunteers.
Using this lesson with a large group enables greater audience participation, but in small group settings this could prove unwieldy.
