Each Practice Test has two parts—Reading and Math. Each test part has 20–32 multiple-choice items that closely resemble the kinds of questions students will have to answer on “real” tests. Each part of the test will take 30–40 minutes for students to complete. The Reading and Math skills measured in these tests and the types of questions are based on detailed analyses and correlations of the five most widely used standardized tests and the curriculum standards measured by many statewide tests, including the following: Stanford Achievement Test CTBS TerraNova Metropolitan Achievement Test Iowa Test of Basic Skills California Achievement Test California’s STAR Test TAAS (Texas) MCAS (Massachusetts) FCAT (Florida) New York How to Use the Tests To use a Practice Test, make a copy of the test or part of the test for each student. Tell students how much time they will have to complete the test. Encourage students to work quickly and carefully and to keep track of the remaining time—just as they would in a real testing session. You may have students mark their answers directly on the test pages, or you may have them use a copy of the Answer Sheet on page 87. The answer sheet may be used with any of the Practice Tests, and it will help students become accustomed to filling in bubbles on a separate answer sheet. It may also make the tests easier for you to score. For the Math section in each test, we do not recommend the use of calculators. For Practice Tests 2 and 6, students will need an inch ruler and a centimeter ruler to answer some of the questions. At the back of this book, you will find Tested Skills charts and Answer Keys for the eight Practice Tests. The Tested Skills charts list the skills measured in each test and the test questions that measure each skill. These charts may be helpful to you in determining what kinds of questions your students answered incorrectly, what skills they may be having trouble with, and who may need further instruction in particular skills. To score a Practice Test, refer to the Answer Key for that test. The Answer Key lists the correct response to each question. To score a Practice Test, go through the test and mark each question answered correctly. Add the total number of questions answered correctly to find the student’s test score. To find a percentage score, divide the number answered correctly by the total number of questions. For example, the percentage score for a student who answers 20 out of 25 Reading questions correctly is 20  25  0.80, or 80%. In your classroom, you might want to have students correct their own tests. This will give students a chance to see where they made mistakes and what they need to do to improve their scores on the next test. On the next two pages of this book, you will find Test-Taking Tips for Reading and Math. You may want to share these tips and strategies with students before they begin working on the Practice Tests. You may also want to post these tips in the classroom and discuss them when students are preparing to take tests. 4 8 Practice Tests for Reading and Math: Grades 7-8 © Michael Priestly, Scholastic Teaching Resources Test-Taking Tips: Reading 1. For each part of the test, read the directions carefully so you know what to do. Then read the directions again—just to make sure. 2. For questions about a reading passage, take a quick look at the questions first. Then you will know what to look for as you read the passage. 3. In each question, look for key words to help you decide what the question is asking. Examples of key words: who, what, when, where, how, why. 4. You do not have to memorize the information in each passage before you answer the questions. Go back to the passage to find the answers you need. 5. To find the sequence of events, look for signal words, such as first, last, then, next, before, after, later, finally. You may also look for numbers, such as years or dates. 6. To figure out the meaning of an unfamiliar word in a passage, look for clues in the sentence. Be sure to look in the sentences before and after the word, too. 7. To find causes and effects, look for signal words and phrases, such as because, so, since, as a result. 8. When answering a question, read all the answer choices carefully. Consider each possible answer before you choose one. 9. To find the main idea of a passage, decide what the whole passage is mostly about. Use the title and any pictures on the page to help you figure it out. 10. Be on the lookout for negative words in questions or directions, such as not, opposite, except, unless. These words may be in all CAPITAL letters, in bold type or italics, or underlined. Questions using these words can be confusing. Think carefully about what the question is asking before you choose an answer. 8 Practice Tests for Reading and Math: Grades 7-8 © Michael Priestly, Scholastic Teaching Resources 5 Test-Taking Tips: Mathematics 1. For each part of the test, read the directions carefully so you know what to do. Then read the directions again—just to make sure. 2. Look for key words and phrases to help you decide what each question is asking and what kind of computation you need to do. Examples of key words: less than, greatest, least, farther, longest, divided equally. 3. To help solve a problem, write a number sentence or equation. 4. Use scrap paper (or extra space on the test page) to write down the numbers and information you need to solve a problem. 5. If a question has a picture or diagram, study it carefully. Draw your own picture or diagram if it will help you solve a problem. 6. Try to solve each problem before you look at the answer choices. (In some tests, the correct answer may be “Not Given” or “Not Here,” so you will want to be sure of your answer. In these Practice Tests, some of the Math questions use “NG” for “Not Given.”) 7. Check your work carefully before you finish. (In many questions, you can check your answer by working backwards to see if the numbers work out correctly.) 8. If you are not sure which answer is correct, cross out every answer that you know is wrong. Then make your best guess. 9. To complete a number sentence or equation, try all the answer choices until you find the one that works. 10. When working with fractions, always reduce (or rename) the fractions to their lowest parts. When working with decimals, keep the decimal points lined up correctly. 6 8 Practice Tests for Reading and Math: Grades 7-8 © Michael Priestly, Scholastic Teaching Resources Name Date Practice Test 1 Reading Directions.

Read each passage. Choose the best answer to each question. Mark your answer. A Narrow Escape Cody woke up and groaned. He’d been having a really strange dream about being in a room with sterile white walls, doctors, nurses, and shots. “Weird dream,” he thought, relieved that it was over. Then he opened his eyes and was blinded by glaring white light. He cringed and closed his eyes again. Then he opened them one at a time, slowly, but the light made his head ache. “Uh-oh,” Cody thought as the room came into focus. His dream hadn’t been a dream at all. Where was he, and what was he doing here? He tried to remember as a robo-nurse came in and began checking the machines in the room. Not ready to face the situation just yet, he pretended he was still asleep. Cody wracked his brain to try to remember how he’d gotten here. He’d been on the subway when an older guy had approached him and whispered, “Run, boy, run!” Cody figured the man was disturbed, but when the train stopped at the next station, three men in silver suits entered the car. Cody saw them coming toward him and knew he should do what the old man had said, but it was too late by then. The three men had him surrounded. “What do you want from me?” Cody demanded, but he already knew that they wanted information. One of the men raised his arm slightly, and Cody was dazzled by the brightest flash of light he’d ever seen. That was the last thing he remembered. “Great,” Cody thought to himself, “just great.” He’d gotten careless and forgotten all his training as a secret agent. He was carrying information on a data chip in his head that would help free the world from the Dictator, but he’d let his guard slip and now he was in a real mess. When the robo-nurse left the room, Cody silently swung his feet over the side of the bed. He looked around and peered at the windows, noticing to his dismay that they were covered by ironwork. It would have to be the door. He was wearing light hospital pajamas and no shoes, but there was no time to search for his clothes now. Cody crept to the doorway and swiveled his head from left to right. There wasn’t a soul in the hall, so he sneaked down to the stairway. Suddenly, just as he reached the second floor, an alarm shrieked. He pelted down the staircase, out the door, into the lobby. A security officer shouted at him and tried to close a barrier over the door, but Cody squeezed through at the last minute, running for his life. He ran as fast and furiously as he could. He heard shouts behind him as the gates ahead began to close, and his eyes scanned the wall for another exit. Out of the corner of his eye, he spotted it—a hole to the right of the gate. He veered off the gravel and over the grass, ducked down, and pushed through the tall hedge until he was free.

He paused. “In the car now, you can ask questions later!” the old man urged. Cody got into the car and the old man stepped on the gas. “It’s about time you showed up,” the old man grumbled. Suddenly, Cody remembered who the old man was. “Thanks, Gramps,” he said. The old man just grunted, but Cody knew he was pleased. They traveled in silence, as if they were just a regular old man and a boy, not freedom fighters on the way to save the world. 12. When does this story take place? during the 1800s F G in the present H during World War II J in the future 13. What happened soon after Cody woke up? A He escaped from the hospital. B He got on the subway. C An old man warned him. D Three men surrounded him. 14. What will Cody and Gramps most likely do next? They will drive back to the hospital to F find information. G They will go to the subway to hide. H They will meet up with other freedom fighters. J They will go to talk to the Dictator. 15. You can tell from this passage that — A Gramps is the leader of the freedom fighters B Cody had lost part of his memory C the guards at the hospital will get Cody back D Cody and Gramps are both robots 16. How does Gramps feel toward Cody in this story? resentful F G afraid H protective J jealous 17. What kind of passage is this?

You probably know the ditty, which goes something like, “This is the song that doesn’t end/Yes, it goes on and on, my friend/Some people started singing it, not knowing what it was/And they’ll continue singing it forever just because—.” Then it repeats over and over again because, of course, it’s the song that doesn’t end. Anyway, my kid brother Jake used to drive me bananas with his rendition of that song. Anytime he wanted something or just felt like being a pest, he’d parade past my room singing it loudly until I surrendered. My brother’s seven years younger than I am, so I guess he craves attention. My mom says he looks up to me, but he sure has a peculiar way of showing it! My brother and his song came in handy one day, though, when I had a conflict with our neighbor. This guy was the crabbiest grouch you’ve ever seen. If you so much as whistled when you walked by his house, he’d stomp out on the porch and yell at you for making too much commotion. My friend Genevieve approached his walk one time to try to sell him a magazine subscription, and he came out and threatened to have her arrested! So anyway, I was riding my bike outside Mr. Grouch’s house when the brakes failed big-time. There was nothing I could do, so I crashed through his gate and onto his walk. It was only seconds before he dashed out of the house screaming at me. I was dazed and all scraped up, but he didn’t care. He just grabbed my bike and stormed back into his house. “Hey!” I yelled. “That’s my bike! Give it back!” “It’s on my property, so it’s MY bike now,” he roared as he slammed the door. I couldn’t believe it. The guy had actually stolen my bike! Try as I might, I couldn’t think of a way to get it back, either. Then a couple of days later as I sat in my room sulking, I heard a terrible racket. I looked out the window, and there was Jake, marching back and forth in front of the neighbor’s house. He was banging a garbage can lid and singing at the top of his lungs, “This is the song that doesn’t end/Yes, it goes on and on, my friend—” “What’re you trying to do, drive me crazy?” screamed the neighbor. “Yep,” said Jake, “and I’ll keep doing it until you return my brother’s bike.” He was out there a good half hour, singing his heart out, before the door opened a crack and my bike flew down the stairs and onto the sidewalk. I watched as Jake ran to grab it and wheeled it down the street back to our house. “Andrew, I got your bike back,” he said as he came in the house.

You’re all right.” He just grinned at me. “So do you want to take me to a movie?” he asked. “Sure thing!” I laughed. After that, I realized that my brother wasn’t so bad after all. I mean, he is a pest sometimes, but in a crunch, I’d rather have him on my side any day! 19. Which of these events happened last? A Jake sang in front of Mr. Grouch’s house. B Genevieve went to Mr. Grouch’s house. C Jake came home with Andrew’s bike. D Andrew crashed through Mr. Grouch’s gate. 22.

You can tell from this passage that — A Andrew wishes he had more brothers B Jake does not know how to ride a bike C the neighbor used to be a nice guy D Andrew and his family live in a suburban neighborhood 24. As far as Andrew was concerned, what was the best thing Jake did? He banged a garbage can lid. F G He paraded past Andrew’s room. H He got the bike back. J He sang a song that did not end.

Read each passage. Choose the best answer to each question. Mark your answer. Man’s Best Friend? Typically, dogs have been called “man’s best friend” because of their important role in human lives. However, the robot may soon succeed the dog as the human’s closest companion. Robots are doing everything from entertaining us to working for us to saving our lives. More people notice robots these days because they have become more visible in the media. There are a few TV shows where robot inventors fight their robots, for example, or robots become super crime fighters, but robots have much more important jobs in our world. Since the late 1950s, robots have been used in many kinds of manufacturing, especially in those jobs in factories that involve repeating the same action over and over again. People get tired or bored in such a situation, but robots do not. Robots can do the same things many thousands of times a day, every day—something people simply can’t do. Robots aren’t just stuck on the assembly line. Scientists are making robots that are more careful than ever. Some can even work on small circuits for electronics. Robots do dangerous jobs, too. They can find and get rid of bombs, for example—a job that’s not safe for people. Bomb robots have arms that lift the bombs and place them into bombproof boxes. In places that have been contaminated by germs, chemicals, or radioactivity, robots are invaluable because they can go where humans cannot. Robots aren’t all work and no play. They’ve become so sophisticated that some people even use them as pets! Robotic dogs and cats are on the market now. While some perform only the simplest functions, others are capable of learning tricks and obeying commands! Robots will doubtless become even more important in society as we become better at making them. Soon they will become widespread in hospitals where they will perform delicate surgery requiring a hand so steady that a human couldn’t do the procedure. Scientists are also in the early stages of developing artificial intelligence in robots, which would allow them to interact fully with humans. That’s when robots may become a human’s best friend.
