Plan a Response by Brainstorming and Outlining - ISEE Lower Level Essay

SECTION 1

Why Planning Matters

Have you ever started telling a story and then forgot where you were going? That happens to everyone! Writers have been using planning for thousands of years to stay on track.

Even the greatest authors don't just sit down and write perfectly. They think first, jot down ideas, and organize them. On the ISEE essay, planning is your secret weapon!

Step 1 • Read the Prompt

You read the essay question carefully. What is it really asking you?

Step 2 • Brainstorm Ideas

You quickly list every idea that pops into your head. No idea is too silly at this stage!

Step 3 • Pick Your Best Ideas

You choose 2 or 3 strong ideas you can explain well with details.

Step 4 • Make an Outline

You organize your ideas into a beginning, middle, and end.

Step 5 • Write with Confidence

Now you write your essay. You already know what to say!

On the ISEE, you get 30 minutes for your essay. If you spend about 3–5 minutes planning, the rest of your writing time goes much faster. Think of it like looking at a map before a road trip!

SECTION 2

Core Principles of Planning

Good planning is built on a few simple ideas. Let's learn the key principles that will make your ISEE essay stand out!

Brainstorming

Brainstorming means writing down every idea you can think of — fast! Don't judge your ideas yet. Just get them on paper.

Selecting

Selecting means picking your 2 or 3 strongest ideas. Choose the ones you can explain with clear details.

Outlining

An outline is a short plan that puts your ideas in order: introduction, body paragraphs, and conclusion.

Supporting Details

Supporting details are the examples, reasons, and descriptions that make your ideas come alive for the reader.

✦

KEY TAKEAWAY

Think of planning like packing a suitcase for a trip. You wouldn't just throw random stuff in! You think about what you need, pick the best items, and organize them so everything fits. A brainstorm is like dumping everything out on the bed. An outline is like neatly packing the best items.

SECTION 3

See How Brainstorming Works

One great way to brainstorm is to use a brainstorm web (also called an idea web). You put the topic in the center and draw lines out to your ideas, like a spider web!

This brainstorm web shows five ideas branching out from the center topic. The writer can now pick the strongest idea — the one they can describe with the most details.

Look at the web above. All five ideas are good! But you only need to pick one. Ask yourself: Which idea can I describe with the most details? That's the one to choose.

💡

ISEE Test Tip

You can also brainstorm with a quick list instead of a web. Just number your ideas 1, 2, 3, 4, 5. Then circle your favorite. Both methods work great!

SECTION 4

How to Build Your Outline

After you brainstorm and pick your best idea, it's time to build an outline. An outline is like a skeleton for your essay. It shows the bones before you add the muscles and skin!

Your ISEE essay outline has three simple parts. Let's look at each one.

Part 1: Introduction

Your introduction is 2–3 sentences. It tells the reader your main idea right away. Think of it like a movie trailer — it gives a preview of what's coming.

Part 2: Body Paragraphs

Your body paragraphs (2 or 3 of them) are where you share your reasons, examples, and details. Each paragraph should focus on one reason or example.

Part 3: Conclusion

Your conclusion is 1–2 sentences. It wraps up your essay and reminds the reader of your main idea. Like saying goodbye at the end of a great visit!

💡

Outline Shortcut

Here's a fast way to write your outline on test day. Just write: Intro: [main idea], Body 1: [reason + detail], Body 2: [reason + detail], End: [wrap up]. That's it! It takes about 2 minutes.

SECTION 5

The Essay Map: See the Whole Picture

Let's look at a complete essay map so you can see how all the parts fit together. This is what your outline should guide you toward!

This essay map shows the flow from introduction to body paragraphs to conclusion. Notice the time guide at the bottom — planning takes only 3–5 minutes but saves you tons of time!

Your outline doesn't have to be perfect or pretty. It's just for you! Even a few scribbled words will help you stay organized while you write.

SECTION 6

Worked Example: From Prompt to Outline

Let's work through an example together, step by step. We'll start with a real ISEE-style prompt and build a complete outline.

Planning Tips vs. Common Traps

Even great writers can fall into traps. Let's compare smart planning moves with mistakes to avoid.

Smart Move ✅	Common Trap ❌
Spend 3–5 minutes planning before writing	Start writing immediately with no plan
Pick ONE main idea and stick with it	Try to write about every idea you brainstormed
Add details and examples that help the reader "see" your idea	Write short, plain sentences with no details
Write a clear beginning, middle, and end	Just stop writing when time runs out
Save 2–5 minutes to reread and fix mistakes	Never look back at what you wrote

Smart Moves vs. Common Traps

KEY TAKEAWAY

Think of your outline like training wheels on a bike. It keeps you balanced while you write. Without it, you might wobble and fall off track. With it, you can ride smoothly all the way to the finish!

SECTION 8

From Planning to Great Writing

Planning is just the first part of writing an awesome ISEE essay. Once you've got your outline, here's how planning connects to the next steps.

Planning Skill	What It Helps With Next
Brainstorming many ideas	Choosing a topic you're excited about — your personality shines through!
Selecting your best idea	Writing with focus — every paragraph supports one clear message
Listing supporting details	Using descriptive language — readers can "see" what you're talking about
Organizing into an outline	Writing with strong organization — admissions officers love this!

How Planning Powers Better Writing

Remember, the admissions officers at the schools you're applying to will read your essay. They want to learn about YOU — your ideas, your voice, and how you think. A plan helps your real personality come through!

ℹ

Looking Ahead

After you master planning, the next skills to practice are writing descriptive details (helping the reader see, hear, and feel your story) and revising (fixing mistakes and making sentences better). You've got this!

SECTION 9

Practice Activities

Time to practice! These activities will help you get faster and more confident at brainstorming and outlining. Let's go!

Question 1: SAMPLE PROMPT WITH MODEL RESPONSE

Read this prompt: "Describe your favorite day of the year and explain why it is special to you." Below is a model response. Read it, then write down what makes it a strong essay.

Show answer

Model Essay: "My favorite day of the year is Thanksgiving. Every November, my whole family drives to my aunt's house in the country. The moment I walk through the door, I smell cinnamon and roasted turkey. My cousins and I play tag in the big backyard while the adults cook. The leaves are red and gold, and the air is cool on my cheeks. At dinner, we go around the table and each say something we're thankful for. Last year, I said I was thankful for my dog, Biscuit, and everyone laughed because Biscuit barked right on cue. Thanksgiving is special because it's the one day when everyone I love is in the same room, laughing and sharing stories. I wish every day could feel like that." Why it works: (1) Clear main idea stated in the first sentence. (2) Descriptive details that use the five senses — smells, sights, feelings. (3) A personal story (Biscuit barking) that shows personality. (4) A strong ending that wraps up the main idea. The writer likely planned by brainstorming favorite days, picking Thanksgiving, listing details (food smells, cousins, leaves, going around the table), and organizing them into a beginning, middle, and end.

Question 2: BRAINSTORMING EXERCISE

Here is a prompt: "If you could visit any place in the world, where would you go and why?" Brainstorm a list of at least 4 different places. Then circle or underline the ONE place you could write about with the most details. Explain why you chose it.

Show answer

Strong example response: Brainstorm list: (1) Paris, France — Eiffel Tower and croissants, (2) the Amazon rainforest — cool animals and huge trees, (3) Japan — sushi and cool technology, (4) the Moon — because it would be amazing to see Earth from space. Best choice: the Amazon rainforest. I chose this because I love animals and nature. I could describe the colorful parrots, huge snakes, tall trees, river sounds, and what it feels like to walk through a jungle. I know the most details about this place, so my essay would be full of interesting descriptions. A strong brainstorm list has at least 4 ideas, and the best choice is the one where you can picture the most vivid details.

Question 3: OUTLINING EXERCISE

Using the prompt "What is something you are really good at? Describe it and explain how you got good at it." create a complete outline with an Introduction (main idea), Body 1 (first reason + detail), Body 2 (second reason + detail), and Conclusion (wrap-up).

Show answer

Strong example outline: Intro: I am really good at drawing. I have loved art since I was little, and I've worked hard to get better. Body 1: I practice every day by drawing things I see — my cat, trees outside, my shoes. My sketchbook is almost full! Body 2: I also learned from my art teacher, Ms. Chen. She taught me about shading and how to make things look 3D. Conclusion: Drawing makes me happy, and practicing every day is how I got good at it. What makes this outline strong: It has a clear main idea (drawing), two reasons (daily practice and a teacher), specific details (cat, sketchbook, shading), and a wrap-up conclusion. This outline could be written in under 2 minutes and would guide a well-organized essay.

Question 4: REVISION EXERCISE

Read this weak paragraph and rewrite it to make it stronger. Add details that help the reader see, hear, or feel what's happening: "My favorite place is the beach. I like the beach because it is fun. I go there in the summer. It is nice."

Show answer

Improved version: "My favorite place is the beach near my grandmother's house. Every summer, I run across the hot sand and jump into the cool, salty waves. I love listening to the seagulls call and feeling the warm sun on my face. My brother and I build huge sandcastles with moats and towers. The best part is sitting on a towel at sunset, eating popsicles while the sky turns pink and orange." Why it's better: The improved version uses sensory details (hot sand, cool waves, salty, warm sun, pink and orange sky), specific actions (running, jumping, building sandcastles), and personal touches (grandmother's house, brother, popsicles). Instead of just saying "it is fun" and "it is nice," the writer SHOWS the reader why the beach is special. This is the kind of detail that an outline helps you plan for!

Question 5: CRITICAL THINKING

Imagine you open your ISEE test booklet and see this prompt: "If you could change one rule at your school, what would it be and why?" Do a full plan: (1) Brainstorm at least 3 ideas. (2) Pick the best one and explain your choice. (3) Write a complete outline with Intro, Body 1, Body 2, and Conclusion. (4) For each body paragraph, include at least one specific detail or example. Try to finish in 4 minutes or less!

Show answer

Strong example: Brainstorm: (1) Longer recess, (2) No homework on weekends, (3) Pets allowed at school. Best choice: Longer recess — I have the most reasons and details for this one. Outline: Intro: If I could change one school rule, I would make recess 15 minutes longer. Kids need more time to play and recharge. Body 1: Longer recess would help kids focus better in class. When I come back from recess, my brain feels fresh. But right now, recess is so short that I barely finish one game of soccer before the whistle blows. Body 2: More recess time would also help kids make friends. My friend Sofia is in a different class, and the only time I see her is at recess. With more time, we could actually finish our conversations. Conclusion: A longer recess would help kids learn better and build stronger friendships. I hope my school will think about this someday! Evaluation: This response earns full marks because it includes a brainstorm with 3+ ideas, a clear reason for the choice, a complete 4-part outline, and specific personal details (soccer, friend Sofia) in each body paragraph. The plan could easily be completed in under 4 minutes.

SUMMARY

Review: Plan a Response by Brainstorming and Outlining

Summary

Planning your ISEE essay takes just 3–5 minutes and makes everything easier! Start by brainstorming — write a quick list or draw an idea web of every thought that comes to mind. Then select your strongest idea — the one you can explain with the most vivid details. Next, build a short outline with four parts: Introduction (your main idea), Body 1 (first reason + details), Body 2 (second reason + details), and Conclusion (wrap-up).

Remember to include supporting details that help the reader see, hear, and feel your story. Use descriptive language and share personal examples that show your personality. Admissions officers want to get to know YOU through your writing. With a solid plan, your essay will be organized, creative, and full of your unique voice. You've got this!
