Some students can carry a conversation but still struggle to choose the right topic to begin with. They might talk only about themselves, default to a favorite interest every time, or miss important clues about what the other person wants to talk about. This can lead to stalled conversations, one-sided exchanges, or unintentional social friction.

The Topic Radar strategy helps students build awareness around the topics they choose and how they affect their communication partner. This printable tool and lesson plan are ideal for helping high school students think beyond their go-to interests and choose conversation topics that are relevant, inclusive, and easier for others to connect to.

In this post, you’ll find:

• An overview of the Topic Radar approach
• A step-by-step lesson plan for classroom, small-group, or 1:1 settings
• Ideas for building generalization through everyday social practice

What Is Topic Radar?

Topic Radar is a strategy that helps students tune into the interests of the person they’re talking to. Rather than focusing only on their own favorite topics, they learn how to select conversation topics that are more likely to be interesting and reciprocal.

Using Topic Radar involves:

• Thinking about the other person’s interests
• Remembering past conversations and shared experiences
• Picking up on visual or environmental clues (what someone is holding, wearing, or talking about)
• Choosing a topic you both know something about

This skill is especially useful for students working on conversation initiation, perspective-taking, and pragmatic language goals.

Why Teaching Conversation Skills Matters

Students are expected to carry conversations across all parts of the school day. Whether it’s during group projects, before class, in the lunchroom, or at extracurriculars, the ability to choose a topic that engages someone else can help students form better social bonds and increase their confidence in peer interactions.

Many students default to:

• Talking about the same topic repeatedly (often a personal interest)
• Picking topics that are too specific or unfamiliar to the other person
• Jumping into a conversation without considering the context

Teaching the Topic Radar framework helps students slow down, observe the setting, and consider what they know about the person they’re talking to. This results in more natural, engaging interactions and increases the chances that conversations will continue rather than fall flat.

Lesson Plan: Teaching Topic Radar

Use this plan in a 25–30 minute session. It can be used in speech sessions, interventions, or general education settings that support conversation skills.

Step 1: Introduce Topic Radar (5–7 minutes)

Begin with a brief discussion:

• “Have you ever started talking about something and realized the other person wasn’t interested?”
• “How can we choose better topics when we’re starting a conversation?”

Explain that Topic Radar helps you choose topics based on what the other person might enjoy or have experience with. It helps conversations feel more balanced and interesting for both people.

Then, introduce the four thinking prompts from the Topic Radar PDF:

• Think about the other person’s interests
• Remember what you know about them
• Look for clues in the environment
• Remember what you have in common

Step 2: Practice Topic Radar (10–12 minutes)

Give students the downloadable Topic Radar PDF and walk through it together. As a group, brainstorm topics for different people based on the clues you would have.

Examples:

• A classmate holding a soccer ball: “How’s practice going this week?”
• A peer who just transferred: “What’s been your favorite part of this school so far?”
• A friend you see at art club: “Are you working on anything new?”

Then, split students into pairs or small groups. Have them take turns choosing a topic based on a short scenario or peer role-play. Encourage students to explain why they picked that topic and how it connects to the person they’re “talking” to.

Step 3: Reinforce Staying on Topic (8–10 minutes)

Once a topic is chosen, help students practice staying with it.

Prompt them to:

• Ask follow-up questions
• Add a related comment
• Listen for signs that it’s time to shift or wrap up

For example: 

• Topic: School musical
• Follow-up: “What’s your role this year?”
• Comment: “That sounds like a lot of lines. I remember how nervous I was last year.”

This step supports longer exchanges and helps students see how good topics lead to better back-and-forth interaction.

Beyond the Lesson: Supporting Generalization

To help students use Topic Radar in real-life settings, you can:

• Create a quick daily warm-up: Ask, “Who’s one person you could talk to today, and what would be a good topic?”
• Use it as a prep tool: Before group work, have students plan two possible conversation openers using the Topic Radar strategy
• Turn it into a classroom visual: Post the four Radar prompts where students can refer to them easily
• Make it personal: Have students create mini Topic Radars for people they talk to often (classmates, siblings, teachers), based on what they know about them

The more students practice choosing topics with intent, the more confident and flexible they become in new conversations.

More Than Just Small Talk

Topic selection is often overlooked as a teachable skill, but it plays a critical role in how students connect with others. When students understand how to pick a topic based on someone else’s interests or shared experiences, they start to approach conversations more thoughtfully.

The Topic Radar activity supports perspective-taking, peer engagement, and social communication. It helps students pause, observe, and choose topics that others can relate to. That shift—from “what I want to talk about” to “what will help us both connect”—is where strong conversation habits begin.
