An informative essay should start by grabbing attention, giving a bit of context, and then clearly stating what the reader will learn (your thesis).

What an informative introduction must do

Your opening paragraph has three core jobs.

  1. Hook the reader (first 1–2 sentences).
  1. Provide brief background or context so the topic makes sense.
  1. End with a clear, focused thesis that previews the main points you’ll explain.

Unlike an argumentative essay, the thesis in an informative essay explains what will be covered, not what you “believe” or want to prove.

Step‑by‑step: how to start an informative essay

Use this simple structure for your first paragraph.

  1. Choose your angle and main points
    • Narrow your topic so you can explain it clearly in a few body paragraphs.
 * Decide on 2–4 key aspects you’ll cover (for example: causes, effects, examples, or steps in a process).
  1. Write a hook (first sentence)
    Good hook types for informative essays include:
 * A surprising fact or statistic
 * A brief, relevant anecdote
 * A thought‑provoking question
 * A vivid description or short scenario

Example (topic: recycling):

Each year, people throw away millions of tons of recyclable materials that could have been turned into new products instead of trash.

  1. Add 2–3 background sentences
    • Clarify what the topic is and why it matters right now (school, community, technology, health, etc.).
 * Define any term the reader must understand before reading the rest.

Example continuation:

Recycling is the process of collecting and processing materials that would otherwise be discarded and turning them into new products. In many communities, recycling programs have expanded, but participation rates still remain lower than they could be.

  1. Finish with a clear thesis statement
    • One sentence that tells the reader exactly what information the essay will cover.
 * Stay neutral and factual; avoid taking sides.

Example thesis:

This essay explains how recycling works, what materials can be recycled, and how increased participation can reduce environmental waste.

Put together, the introduction flows naturally from hook to thesis and sets up the body paragraphs.

Example mini‑intros (with structure highlighted)

Here are quick patterns you can copy and adapt.

  1. Fact hook + context + thesis
    • Hook: surprising fact
    • Context: explanation of the topic
    • Thesis: “This essay will explain…” style Example (topic: sleep and students):

More than 70% of high school students do not get enough sleep on school nights. (Hook – statistic)

Sleep is essential for concentration, memory, and emotional health, yet busy schedules and late‑night screen time keep many teenagers awake far too late. (Context)

This essay examines how sleep affects academic performance, what causes sleep deprivation in teens, and which simple habits can improve sleep quality. (Thesis)

  1. Question hook + brief definition + thesis
    Example (topic: social media algorithms):

Have you ever wondered why the same types of videos keep appearing on your social media feed? (Hook – question)

Behind every post you see is an algorithm, a set of rules that decides which content you are most likely to watch, like, or share. (Context/definition)

This essay explains how social media algorithms work, which factors they consider, and how they influence what users see online each day. (Thesis)

  1. Short anecdote hook + context + thesis
    Example (topic: online learning):

On the first day of online classes, Mia realized she could attend school from her bedroom in slippers instead of rushing for the bus. (Hook – anecdote)

Online learning has changed the way many students access education, offering more flexibility but also new challenges. (Context)

This essay explores the main features of online learning, its benefits for different types of students, and the obstacles that can make it difficult. (Thesis)

Simple formula you can reuse

Think of your introduction as an “elevator pitch” for your topic: quick, clear, and informative.

You can use this fill‑in‑the‑blank style template:

Hook sentence about your topic (fact, quote, question, or mini story).
One or two sentences that explain what the topic is and why it matters.
Thesis: “This essay will explain/show/describe [main topic] by focusing on [point 1], [point 2], and [point 3].”
