Adding and Subtracting Decimals! Steps for Adding Decimals 1. Line up your decimals 2. Add *Add zeros if you need to hold any places!* Steps for

Subtracting Decimals 1. Line up your decimals 2. Subtract Real Life Example Emily went to the grocery store to buy ice-cream. She spent $5 on chocolate, $7.34 on strawberry, and $6.87 on vanilla. How much did Emily spend total? Letter This is an addition problem, so you have to add up all the prices. You should line up your decimals first.

The $5 doesn't have a decimal, so what do you have to do? $5

+7.34

6.87 ____________ You have to add zeros to keep it even. $5.00

+7.34

6.87 _______ This but this Since you have your decimals correctly lined up,

all you have to do is add! _______ 1 1 The total price Emily paid for the ice-cream is $19.21. *Add zeros if you need to hold any places!* Decimals at the Pet Store! I'm terribly sorry you have been sick. You're going to have to make-up work in all your classes, so I'm writing you now to maybe make your life a little easier when you get back to school. In this letter are some notes you need to copy into your math notebook. I will put stars (*) by the important things you need to write down.

We have been learning about decimals. You will see numbers with decimals mostley in money. Adding and subtracting decimals numbers will be very useful in your life. It's one of those skills that you actually WILL use! You'll use this when you are dealing with banking, shopping...etc. Basically anytime you use money, you will also be adding and subtracting decimals numbers! This is a simple skill, and I know you will catch on very easily! Also, by the time you write these few notes down, you won't have to worry about catching up with math when you return to school.

Let's start with adding decimal numbers. The thing you always need to remember is to LINE UP YOUR DECIMALS! If you don't line your decimals up with each other, your answer will be wrong! If the problem is written horizontally, change it to vertically; it's just like adding with whole numbers. If your addends don't have the same number of digits in them, you can add zeros. Adding zeros doesn't change the value of the number at all! Another very important step is to bring down your decimal into your answer when you are finished adding. If you don't bring it down, your answer will be read as a whole number! So, here are you steps, or procedures, you need to follow every time:

*1. Line up your decimals.

*Add zeros if you need to hold any places!*

*2. Add.

*3. Bring down your decimal.

See how easy that is, Bailey? Just follow those steps every time, and you should get the right answer!

Subtracting decimals is basically the same. Just remember to always line up your decimals. When you subtract and your digits don't line up, you can do the same thing as addition: you can add zeros to any of your numbers. This is an important thing to do because if your numbers are misaligned, your whole answer will be wrong. Just like with addition, you have to bring down your decimal into your answer. Here are the subtracing decimal notes:

*1. Line up your decimals.

*Add zeros if you need to hold any places.

*2. Subtract.

*3. Bring down your decimal.

I told you it's the same thing except you subtract! I'm sorry your sick, but it's good you missed such an easy lesson because you can catch up really fast!

That raps up the math lesson you have missed. Make sure you copy those notes, and you will be fine when you return to school. If you have any questions, you can reply to this letter, or just ask when you come back. I hope you feel better soon, best friend! 3. Bring down your decimal 3. Bring down your decimal Sincerely,

that is what my picture is! (This scene is a girl (Asheton) buying gifts for her dog, Penny. This is an ordinary day in a Pet Store.)

Asheton: Okay. Today I'm at the Pet Store, and I have $10 to spend on my dog, Penny. So let's see what we can find for her.

(looks around the store, then picks up a toy)

Asheton: It's Snoopy! She would love this! Oh I have to get this for her; does it squeak?

(squeaks the toy)

Asheton: It does! It's $5.32. I'll take it. Let's move on!

(walks and finds a bird)

Asheton: Hello! You're a very pretty bird, you're a very pretty bird! Do you cost $10 because I could put the Snoopy toy back. Oh no. Nevermind, I'm $90 short. Well maybe I'll get you when I save up. Bye-bye!

(finds Hermit Crabs)

Asheton: Hermit crabs...cool! Look at this cute bandana! (picks it up) Aww that would just be so precious around Penny's neck! I have to get this! Okay it's $3.41. So do they have anything for her to eat here? They have to because she needs some treats.

(walks over to the food)

Asheton: Here they are. I can either get "Crunch n' Clean" or "Smarties!" Umm, I'll go with the "Smarties" because they're cheaper and she likes them better, I bet. So that's $1.00. Now let me make sure I have enough to buy all this because, like I said, I have $10 to spend on her today. So I'm going to add up all my prices.

(adds up the prices)

Asheton: $9.73 is what I'm going to spend today, and I can buy it because I have enough! I hope Penny likes her gifts! Acting it Out Dutch mathematician, Simon Stevin, is credited for decimals. He was the first to present decimals clearly. He also explained how decimals are much easier than the use of fractions. He was born in 1568 and died in 1620.

Simon Stevin loved math and science. He was an excellent engineer! He could build windmills, locks and ports. In school, he studied Latin and Greek. In 1583, he attended the University of Leidan. Another thing Simon did was he founded the engineering classes at that university. He also wrote textbooks! His best work was called “Art of Tenths.” In the intro of “Art of Tenths”, Simon says that the purpose of the book is to teach people how to do math without regular fractions. In his life, he also had a few jobs. He was a bookkeeper, cashier, and a clerk in a tax office.

That’s a little bit about the mathematician, Simon Stevin. Because he loved math, he was able to figure out what we still use today! If you would like to learn more, visit these websites (my sources):
