Time and Money:

Money Math Challenge
you know that if you cut a big, long carrot up into round disks, sideways,
those are called "carrot coins"? With a grown-up's help, make yourself a pile
of carrot coins. Then "spend" them into your tummy with a big glass of cold
Play money, real money, or money

On Martin Luther King Day, and every day, we celebrate equality.
Realizing that two things are equal is really important in math.
"Equal" is where we get the word "equation," and equations are
what math is all about.
In real life, noticing that things are equal is important, too.
When it comes to money, you could say that the "price" of something is how much
money it is "equal" to.
So let's challenge ourselves to say and write how much money each
of these cards equals. (If you don't have money flash cards, lay out different
quantities of bills and coins for each round of the game.)
You can either do this individually, or form into
partners or teams and compete against others.
Have a piece of scratch paper and a pencil ready.
The leader will hold up a card that has a picture of a coin, several coins, and
maybe a paper bill or bills. Look at the picture of the money, and say aloud
how much it "equals."
When you know you are right, then write down the
amount properly on your scratch paper. Use the $ and ¢ signs.
For example, one penny equals one cent and
you write it like this: 1¢, or $.01.
One dollar equals 100 cents, and you write it
like this: $1 or $1.00.
A five-dollar bill and two nickels equals
Too bad a money prize isn't appropriate . . . but
maybe the winner can have 10 "carrot coins"!
