Samuel couldn’t wait to show his mom and

grandma the new skateboard he had just gotten from

Ben. Ben couldn’t wait to give his sister the new shawl

he had just gotten from Samuel. Ben and Samuel were

best friends!

Samuel’s grandma had worked for weeks

knitting the shawl. Ben had wondered for weeks

what to get his sister for her birthday. Then one

night Ben saw the shawl Samuel’s grandma was

knitting. He knew his sister would love it!

Samuel spent every day after school skateboarding

with Ben. Samuel wished for his own skateboard.

Ben knew how much Samuel would love

having a skateboard. Suddenly

a trade was born!

Trading one thing for

another was a way of life.

Samuel’s mom and grandma

remembered when people

used something called

money instead.

16

RGEN14_SLTH2_U2_W1.indd 16 7/3/13 3:36 PM

Money paid for things they

needed. Samuel and Ben were too

young to remember that time.

Sometimes, Samuel’s mother opened a secret

drawer in her jewelry box. She let him hold the shiny

coins and smooth dollar bills she had saved. Then

they were put away for safekeeping.

People no longer used money. They traded things

instead. Samuel couldn’t imagine life any other way.

Samuel knew how to draw, so he always traded his

drawings to get what he wanted. His family and Ben’s

family traded often. Samuel didn’t understand why

anyone might need money. Trading was so

much easier!

Sleuth WorkGather Evidence How can you tell that this story takes place some time in the future? Write details that support this.

Ask Questions If you could talk with Samuel and Ben, what questions would you ask them about life without money? Write two questions.

Make Your Case What is the most important idea the writer wants to share about trading? What information is given to support that idea?

Have you ever visited an ATM? Did you stare in wonder when, like magic, money came out of the machine? Several decades ago banking wasn’t so convenient.

People use banks to safely keep and save money. Then, when they need to spend it, they withdraw the money. That’s hard to do if your bank isn’t nearby. It’s even harder to do if your bank is closed. So how do you get cash when you need it?

In the early 1970s, the first ATM, or automated teller machine, was introduced. ATMs are machines. Using a plastic bank card and a PIN, or personal identification number, people can access their bank accounts. They can do this at any time of day or night or even when the bank is closed. They can withdraw money, and they can deposit money

18

RGEN14_SLTH2_U2_W2.indd 18 7/9/13 4:34 PM

and checks. What’s even more helpful is that ATMs can be found everywhere!

Banks are adding new ATM services every year. For example, people can now deposit checks without using an envelope. That’s because ATMs scan, or read, checks. Another improvement is talking ATMs. These machines have audio, so people who cannot see well or at all can access their bank accounts by listening to instructions.

ATMs keep improving. Some ATMs now have video screens. A banker uses the video screen to talk with the person using the ATM. Other banks are even testing ways mobile phones can be used at ATMs. Just imagine what ATMs will be able to do next!

Gather Evidence How are modern ATMs different from ATMs from the early 1970s? Give at least one piece of evidence from the text.

Ask Questions After reading the text, what ATM service would you like to learn more about? Write a question to guide your research.

Make Your Case What information does the writer give to support the idea that ATMs are more than cash dispensers?

For weeks, I had seen a big, red circle on the calendar. It was my parents’ anniversary. I got the sense this was an important day, and I wanted to do something to celebrate . . . but what?

Mom had once told us that Dad asked her to marry him after taking her out for pizza and a romantic movie. We decided to have a movie night that Mom and Dad would never forget.

We bought the ingredients

to make Mom’s favorite pizza. My

older sister Bethany found out what movie they had seen, and we rented it for the night. But everything started to go wrong.

20

RGEN14_SLTH2_U2_W3.indd 20 7/3/13 3:36 PM

First, the pizza slid off the pan and onto the floor as I carried it to the table. Next, Bethany burned the popcorn, so the whole house smelled awful. Then we discovered that the DVD wouldn’t play. Bethany and I were upset, but Dad chuckled as he opened a window to air out the house. He took us out to dinner, to the same restaurant

where he and Mom had eaten that special night. Over pizza,

we heard the story of how Mom and Dad met. It was better than the best romantic movie—even without popcorn!

Look for Clues What clues can you find to show that Mom

and Dad were not upset about the problems that happened with the surprise?

Ask Questions After reading the text, what questions would you ask someone who is celebrating a special day?

Make Your Case Choose words the writer used to describe her feelings. Replace them with words that have similar meanings. Read the story aloud. 21
