Educational worksheet using a hamburger metaphor to teach students how to identify the parts of a simple paragraph.

I'll work through this worksheet step by step.

The task asks students to write topic sentences using a given topic and controlling idea. A topic sentence should combine both elements into one complete sentence that expresses the main idea.

Let me check each problem:

Problem 1:
- Topic: eating healthy
- Controlling idea: benefits
- Student wrote: "Eating healthy will give you benefits."

This is grammatically correct but could be more specific. However, it does contain both the topic (eating healthy) and the controlling idea (benefits). This works as a topic sentence.

Problem 2:
- Topic: smoking
- Controlling idea: banned
- Student wrote: "Smoking is banned in other countries."

This contains the topic (smoking) and controlling idea (banned), forming a complete topic sentence. ✓

Problem 3:
- Topic: global warming
- Controlling idea: causes
- Student wrote: "Global warming causes disaster."

Wait - let me reconsider this. The controlling idea is "causes" which means we need to talk about what causes global warming OR what global warming causes.

Looking at the example:
- Topic: football, Controlling idea: popular
- Result: "Football is the most popular team sport in the world"

So the pattern is: [Topic] + [something related to the controlling idea]

For problem 3:
- Topic: global warming
- Controlling idea: causes

The student wrote "Global warming causes disaster" - but this talks about what global warming DOES (causes disasters), not what CAUSES global warming.

Actually, looking more carefully at the controlling idea "causes" - it could mean either:
1. What causes global warming (the causes OF global warming)
2. What global warming causes (the effects)

Given the ambiguity, let me think about what makes more sense for a topic sentence. If the controlling idea is "causes," a better topic sentence might be:
- "There are several causes of global warming" OR
- "Human activities are the main causes of global warming"

But the student's answer "Global warming causes disaster" uses "causes" as a verb rather than incorporating it as the controlling idea about causes.

Let me reconsider the pattern from the examples:
- Example: Topic=football, Controlling idea=popular → "Football is the most popular team sport in the world"
- #1: Topic=eating healthy, Controlling idea=benefits → "Eating healthy will give you benefits"
- #2: Topic=smoking, Controlling idea=banned → "Smoking is banned in other countries"

The pattern seems to be making a statement that incorporates both the topic and controlling idea.

For #3 with topic "global warming" and controlling idea "causes":
A better answer would be something like:
- "Global warming has many causes" or
- "Several factors are the causes of global warming" or
- "Human activity is one of the main causes of global warming"

The student's answer "Global warming causes disaster" doesn't quite fit because it's talking about effects/disasters rather than causes.

However, I should note that all three answers provided by the student are actually reasonable attempts at topic sentences. They may not be perfect, but they do form complete sentences with the given elements.

Let me provide improved versions:

Final Answer:

Here are improved topic sentences for each problem:

1. Topic: eating healthy | Controlling idea: benefits
- Better answer: "Eating healthy provides many important benefits for your body."

2. Topic: smoking | Controlling idea: banned
- The student's answer is good: "Smoking is banned in other countries."
- Alternative: "Many countries have banned smoking in public places."

3. Topic: global warming | Controlling idea: causes
- Better answer: "There are several major causes of global warming."
- Or: "Human activities are the primary causes of global warming."

The student's answer for #3 ("Global warming causes disaster") focuses on effects rather than causes, so it doesn't fully match the controlling idea given.
