What Happens in Part 5
Now the stories tip fully into the surreal — the strange, dreamlike, impossible. First, Jenny drinks prune juice and, oddly, begins to read a story completely in reverse, back to front. Then a substitute teacher arrives while Mrs. Jewls is away, and the whole class plays a marvelous trick: every single student claims to be named Benjamin, throwing the poor substitute into total confusion. Finally comes the most famous impossibility of all. Allison somehow ends up in the classroom on the nineteenth floor — the floor that does not exist — taught by Miss Zarves, the teacher who is not real. There she is trapped in endless, pointless busywork until she finds a clever way to escape back to the world that makes sense. These chapters are pure fantasy, bending the rules of reality into a wonderful, dreamlike knot.

💭 Before You Read · Warm-Up (not scored)
There are no wrong answers here — just think, guess, and talk:
Allison ends up in a classroom that does not exist, taught by a teacher who is not real. Why can impossible, dreamlike events be so fascinating to read?
The class fools the substitute by all claiming to be Benjamin. Why do you think a class enjoys pulling a trick like that together?
Predict: Allison escapes the unreal nineteenth floor. How do you think the strange rules of that place might work?

🧠Knowledge Bank · How Sound Reaches You
Physics of Sound · Vibration and MusicWayside is a loud place: bells, voices and a classroom full of racket. All of it is real physics. A sound begins when something vibrates, and the shaking spreads outward through the air as waves of squeezed and stretched air until it reaches the tiny drum inside your ear. Vibrations that arrive jumbled and random we call noise; vibrations that follow a steady pattern of beats and pitches we call music. So the difference between a lovely tune and an unbearable din is really a matter of order, the same pattern-making that lives inside mathematics. Sound explains something small and sad here as well, because a voice can be buried under a big enough wave of noise. Listening for the pattern under a sound is a lifelong skill.

Comprehension
How well do you understand Chapters 17–19?
🧠Knowledge Bank · When the Rules Change
Reading Skill · Tracking Story RulesUntil now this book has been silly but broadly possible. Here it tips over into the genuinely strange, and a careful reader notices the moment a story changes its own rules. Jenny reads an entire tale backward. A girl walks into a classroom on a floor the building does not have, taught by someone the school insists is not there. These are not exaggerations of ordinary life; they are impossible, and impossibility asks for a different kind of attention. The missing nineteenth story was a passing joke in the earlier book, and now it opens into a full strange adventure, a reward for anyone who remembered. Keep asking how far an event bends reality, and the strangest chapters stop being confusing and start being fantasy.

Literary Elements
Understanding HOW and WHY Louis Sachar tells the story across Chapters 17–19.
🧠Knowledge Bank · When Reality Bends
Literary Craft · The SurrealThe surreal is a special flavor of fantasy in which the ordinary rules of the world quietly dissolve, the way they do in dreams. Exaggeration only makes things bigger; surreal writing makes them impossible, and does it calmly, never pausing to apologize or explain. A story told from its last word back to its first, a corridor leading somewhere no corridor could go, a class nobody outside can find: none of it is accounted for, and that refusal is the point. Even so, a dream has its own logic, and so does this one, with events following each other by a floating, sideways sense that feels right while you are inside it. Surreal stories free the imagination completely, and their pleasure lies in surrender.

Dramatic irony is when the reader knows something a character does not (we know Benjamin’s real name). Fantasy is a story with impossible, magical elements (a floor that does not exist). A running gag is a joke repeated across the book — Benjamin’s name again.

Think Deeper
Four deeper challenges — no single-word recall. Read, weigh the evidence, and reason it through.
🧠Knowledge Bank · The Wish to Be Noticed
Thinking & Character · Being OverlookedUnder the strangeness of this part runs a very human ache: the wish to be seen, counted and known to be real. Sachar makes that feeling literal. He imagines a place for the people nobody remembers, a room whose lessons no one checks and whose class no one misses, and the joke turns quietly cold once you notice how closely it resembles the ordinary experience of being overlooked. Almost everyone has sat in a crowded room feeling invisible. Because the situation here is impossible, we can look straight at that feeling, laugh, and still carry the point home with us. Noticing the quiet people around you is a small act with a large kindness inside it, and being truly seen is one of our deepest needs.

Read the passage (the highlighted words are tested below), then answer the questions below. Tap an answer to select it, then tap it again to confirm — you can change your choice until you confirm.
Wayside School has a classroom on a floor that does not exist — and, strangely, real life has something similar. Step into the elevator of many tall buildings and you may notice the buttons jump straight from 12 to 14, as if there were no thirteenth floor at all. Of course, the floor is really there; the builders simply gave it a different number. Why? Because of an old superstition that the number thirteen brings bad luck. To avoid worrying certain guests, many hotels and office towers quietly omit the label ‘13’ and call that floor ‘14’ instead. There is no real danger, of course, and no missing space — only a missing name. It is a small, harmless way to reassure people who feel uneasy. So the next time an elevator seems to skip a floor, remember: the floor has not vanished at all. Like Wayside’s impossible nineteenth story, it is a reminder that people can agree to pretend something is not there, even when it plainly is.
