Word parts got you close. Now the sentence finishes the job. A writer who uses a hard word almost always leaves a clue nearby — a definition tucked in, an example, a word like but that flips the meaning, or a cause that gives it away. There are five kinds of clue and a handful of signal words that announce them, and once you know them you stop skipping words. Five tabs — cards for the five kinds, hints with the signal words on one page, a quiz that asks you to name the clue you used, and a workshop where you sort sentences by their clue, put the guess-and-check steps in order, label a sentence and say why skipping a word costs more than guessing.
One word in this sentence you have never seen. Skip it and the sentence only tells you that he was something, which is almost nothing.
A writer who uses a hard word usually leaves a clue nearby on purpose. Find the signal word, use the clue to make a guess — reading a CONTRAST backwards — then put your guess back in place of the word and check the sentence still makes sense.
Two things people get wrong
⚠️People often think…
I do not know that word, so I will skip it and keep reading.
Skipping looks free and is the most expensive thing you can do: the word was holding the sentence up, and nothing warns you it has gone. A guess costs five seconds and is testable — substitute it, and the sentence either stands or it does not.
A guess announces itself when it fails. A skip never does.
⚠️People often think…
The clue word is near the hard word, so it must mean roughly the same thing.
Only if the signal word says so. With or, which is or such as, read forwards and take it. With but, unlike or however, the clue is the OPPOSITE — in “He was timid, unlike his bold sister,” taking bold as the meaning gets you exactly backwards.
The signal word tells you which direction to read.
Signal, guess, substitute, check
1Watch one
Work out what arid means in: “The soil was arid, so nothing would grow.”
Read to the end of the sentence first — the clue here comes after the hard word.
Find the signal word: so. That announces a cause and its effect.
Work backwards from the effect: nothing would grow. What kind of soil does that? Very dry soil.
Substitute and check: “The soil was very dry, so nothing would grow.” It stands up, so the guess is good.

💬One sentence, then you move on
Why is a guess you check better than skipping the word?
3Try one
What is the LAST step, after you have made a guess? Write one word.
I want a hint first
You put your guess back into the sentence and see what happens.
Where this goes
Where this lives
Every science page hands you new words in a rush — six in a paragraph is normal. Nobody can stop six times, and this is the only method fast enough to keep up.
What this feeds
Next room: once you can read the words, what is the whole paragraph actually saying?
Find one word you do not know today and guess it from its sentence.
One card at a time — tap “Show me” to check yourself, then Next. Start at Foundation; when those feel easy, climb.
Helpful Hints
🧭 The unit in one line
Read to the end of the sentence → look for a signal word → use the clue to make a guess → put your guess back in place of the hard word and see whether the sentence still makes sense.
Guess, then substitute and check. Never skip.
🔑 The one idea
A writer who uses a hard word usually knows it is hard, so they leave a clue nearby on purpose. Your job is to find the help they already left you.
⚠️ Traps to avoid
Do not skip the word. Skipping costs you the sentence, and often the paragraph — a guess you check costs you five seconds.
The clue is not always in the same sentence. Look at the one before and the one after before you give up.
A signal word like but or unlike means the clue is the OPPOSITE of the word. Read it backwards or you will get the meaning upside down.
Always substitute your guess back in. A guess that sounds fine on its own can break the sentence it came from.

🎯 How you will be asked
“What does the underlined word mean?”
“Which words in the sentence helped you?”
“What kind of clue is this?”
“The word but appears. Is the clue the same as the word or the opposite?”
“Replace the hard word with your guess. Does the sentence still work?”
✅ Before the test, can you…
Name the five kinds of clue?
Spot such as, but, because and which is, and say what each one is announcing?
Explain why a contrast clue has to be read backwards?
Substitute a guess back into a sentence and judge it?
Say what it costs you to skip a word you do not know?

Workshop
Work like a reader who never stops: sort twelve sentences by the kind of clue they hold, put the four steps of guess-and-check in order, label the parts of a clue sentence, then say why skipping costs more than guessing.

This is your record of the module on screen — it stays here and goes nowhere. Independent means you got it right on the first tap; supported means you got it after the explain-and-retry, or marked ‘I had it’ on a revealed answer. Both count, and neither is a grade. If your teacher asks, copy the row or show them this screen.
