 Introduction
Math Mammoth European Money is a worktext that covers money-related topics usually encountered
during grades 1-3. The book contains both textbook explanations and exercises, and is designed to be very
easy to teach from, requiring very little teacher preparation (you do need to find practice coins before the
lessons).
The book starts with first-grade topics such as counting coins with cent-amounts and easy problems about
change. For the most part, these lessons use "c" as a symbol for cents. I realize there is no official symbol
for cents, but when young children are learning to count coins, it is much more natural to count them as
cent-amounts, and not use the euro symbol such as in €0.08 to mean 8 cents.
While these initial lessons use pictures for the coins, practicing with real coins is, of course, even better,
and you should have real money on hand to practice with.
From there, the lessons advance toward second-grade, and finally to third grade topics, such as practicing
with euro amounts, and figuring out total bills and change. Therefore, you can also let your child work the
pages of this book in different time periods, and not go through it all at once, depending on your child's
current level.
Making Change explains two basic ways of finding the change: counting up, and subtracting (finding the
difference). This is all done with mental math. The next lesson also practices money problems using
mental math.
In the last lesson we solve money problems by adding and subtracting money amounts vertically (in
columns).
On the next page you will find a list of money activities and games on the Internet.

I wish you success with your math teaching!

(euro cent).
We write 2 c. = 5 c.
We write 1 c.

In the exercises we use small pictures of these coins.

Can you tell which is which?
Do not confuse these coins! They are all copper-colored. The five-cent
coin is the largest of these three, and the two-cent coin is larger than
the one-cent coin. To be sure, look at the number written on them.

To find the total cent-value, add the cent-values.

It's called counting up. Start counting with
the coins of the largest value.

If the cent-amount ends in 5, 6, 7, 8, or 9, it is good to use the five-cent coin.

3. Make these amounts of money in different ways. Use five-cent, two-cent- and one-cent coins.
You can either use real money or draw red circles with “5”, with “2” and with “1”.

a. 8 cents b. 6 cents c. 11 cents

Similarly, when the cent-amount is more than 20 cents,

it is good to use the twenty-cent coin. It is not wrong = 31 c

 Change

When you buy something in a store, you often do not have the exact amount of money to pay
for it. Instead, you give the clerk more money than what the item costs. The clerk then gives
you some money back. This is called your change.
A pen costs 55 cents. You don't have the coins to make exactly 55 cents, so you give the
clerk 60 cents. That is 5 cents too much! But then the clerk gives you back 5 cents, which is
your change.

You gave: Your change:

Price: 55 c 60 c 5c

The clerk gives you back the difference between the price and what you paid.

In the problems below, find the change you get back. Think of the DIFFERENCE between the
price and what you pay; or, think how many cents you paid “too much”. That's your change.
You can set up a “play store” to do these problems, using real money, one person as a clerk, and
one person as a customer.

1. Write how many cents you give, and how many cents you get back in change.

However, you can pay with a larger bill, and get back some change.
To give change, or to check the change you are given, count up from the price of the item until
you reach the amount the the customer gave.

To find any difference, you can:
 subtract the price from the money given, or
 add up from the price to the money given.
