This is an introduction to dimes, nickels, and pennies. First, I show you dimes and pennies, and we work with those only. This is easy since they are your tens and ones. Then I explain what a nickel is (5 cents), and we work out the total for various coin combinations, keeping in mind that two nickels make 10 cents.
