Argumentative writing worksheet for organizing claims, reasons, and evidence.

This worksheet helps you plan an argument by organizing your main claim, the reasons that support it, and the evidence for each reason.

Let’s walk through how to fill it out step by step:

---

Step 1: Write Your Claim/Thesis

At the top, under “CLAIM/THESIS,” write one clear sentence that states what you’re trying to prove or argue. This is your main point.

Example:
*“Schools should start later in the morning because it helps students get more sleep, improves focus in class, and reduces stress.”*

Step 2: List Three Reasons (#1, #2, #3)

Under “REASONS,” think of three strong points that back up your claim. Each reason should be a short phrase or sentence.

Using the example above:
- #1: More sleep leads to better health.
- #2: Students pay attention better when they’re well-rested.
- #3: Starting later lowers anxiety and rush in the morning.

Write these in the boxes labeled #1, #2, and #3.

Step 3: Add Evidence for Each Reason

Now, for each reason, find two pieces of evidence. Evidence can be facts, quotes, statistics, or real-life examples.

For Reason #1 (“More sleep leads to better health”):
- Evidence 1: The CDC says teens need 8–10 hours of sleep; most don’t get enough with early school times.
- Evidence 2: A study from Stanford showed students who slept more had fewer sick days.

For Reason #2 (“Students pay attention better...”):
- Evidence 1: Teachers report fewer yawns and more participation after lunch if school starts later.
- Evidence 2: Test scores went up in districts that switched to later start times (example: Minneapolis Public Schools).

For Reason #3 (“Starting later lowers anxiety...”):
- Evidence 1: Surveys show students feel less rushed and stressed when they have time to eat breakfast and arrive calmly.
- Evidence 2: Bus schedules became smoother and tardiness dropped after changing start times.

Write each piece of evidence under the matching reason column.
