Deeper thinking: inference
In 4th grade, readers move from what the text says to what the text means. An inference is a conclusion you reach by combining text clues with what you already know — reading between the lines.
Example: “The ground was wet and puddles formed in the driveway.” Inference: it had rained recently. (Clue: wet ground + puddles. Knowledge: rain makes puddles.)
The inference formula
Text clue + What I know = Inference
- Find a clue in the text.
- Connect it to what you already know.
- State your conclusion.
Text structures in nonfiction
Nonfiction is organized in patterns. Learn the signal words:
| Structure | What it does | Signal words |
|---|---|---|
| Sequence | order of steps/events | first, then, finally |
| Cause & effect | reason → result | because, so, therefore |
| Compare & contrast | similarities/differences | like, unlike, whereas, both |
| Description | explains a topic | for example, such as |
Comparing across texts
Readers also compare ideas between two passages. Ask: What does each text say? What’s the same? What’s different? Writers organize these comparisons with compare/contrast language.
The 4th grade routine
- First read: grasp the topic and main idea.
- Second read: look for structure signal words.
- For each question, decide: stated fact or inference?
- Support every answer with the text.

Frequently Asked Questions
What exactly is an inference?
An inference is a conclusion you reach by combining clues in the text with your own knowledge. The author doesn't say it directly — you figure it out.
Why does text structure matter?
Recognizing structure (sequence, compare/contrast, cause/effect, description) helps readers organize information and predict how the text will flow.
