Nickel
A nickel is worth five cents. That means that five pennies and one nickel are worth the same thing.
Now if you take four pennies + one penny, you will get five pennies or one nickel.
Now how many nickels are in one dollar? There are twenty. That is because if you split up one
hundred pennies into equal groups of five, you will end up twenty groups. Try it with M&Ms.
