Worksheet for identifying the main idea in paragraphs, featuring three example texts and instructional guidance.

Let's solve this worksheet step by step. The goal is to identify the main idea of each paragraph — the sentence that best summarizes the entire paragraph. We’ll underline the sentence that contains the main idea in each case.

Paragraph 1:

> Students who experienced studying remotely had to make a tremendous adjustment when they came back to the physical classroom. This is not surprising because after walking straight to their computer chair, they have to experience traveling to school again. Also, teachers will have total control of the academic location since they can now monitor everything unlike during virtual classes, and this is something students need to always be reminded of. Finally, students will now need to study independently at school compared to remote learning where they could be assisted by their parents or guardians.

✔ Main Idea:
The first sentence states the overall point: *Students who experienced studying remotely had to make a tremendous adjustment when they came back to the physical classroom.*

All the following sentences give reasons for why this adjustment was difficult (traveling to school, teacher control, independent study). So the main idea is clearly stated at the beginning.

🔹 Underline this sentence:
Students who experienced studying remotely had to make a tremendous adjustment when they came back to the physical classroom.

Paragraph 2:

> In a dowry system, the parents of the bride spend a lot of money just to get their daughter married. This is one of the reasons why it sometimes reduces the sacred affair of marriage. To some, the dowry system is considered as an evil in society.

✔ Main Idea:
The first sentence introduces the topic: *In a dowry system, the parents of the bride spend a lot of money just to get their daughter married.*
The next two sentences explain why this is problematic — it reduces marriage’s sanctity and is seen as evil.

So the main idea is still the first sentence, as it sets up the discussion.

🔹 Underline this sentence:
In a dowry system, the parents of the bride spend a lot of money just to get their daughter married.

Paragraph 3:

> Gambling for some is a form of relaxation regardless of whether they win or lose the money they bet. For others, gambling is unforgivable whatever the situation is. Some countries allow it and even create a center for it. Others totally ban it whether it is small-scale or large-scale gambling. Gambling is treated differently by different people.

✔ Main Idea:
This paragraph discusses different views on gambling — how people and countries treat it differently. The last sentence wraps up the whole idea: *Gambling is treated differently by different people.*

While the first sentence starts with a personal view, the paragraph builds toward the broader idea that attitudes vary widely. The final sentence summarizes the entire paragraph.

🔹 Underline this sentence:
Gambling is treated differently by different people.

✔ Final Answers (with underlined main ideas):

1. Students who experienced studying remotely had to make a tremendous adjustment when they came back to the physical classroom.
2. In a dowry system, the parents of the bride spend a lot of money just to get their daughter married.
3. Gambling is treated differently by different people.

📝 Explanation Summary:

- The main idea is the central thought of a paragraph.
- It may appear at the beginning, middle, or end.
- Supporting details follow or surround it.
- In these paragraphs:
- Paragraphs 1 and 2 have the main idea at the start.
- Paragraph 3 has the main idea at the end, summarizing the contrast in opinions.

This helps students recognize that main ideas aren’t always in the same place, but they are always the most general statement that other sentences support.
