Teaching Demo Lesson Plan Ideas: What Principals Actually Want to See

The teaching demo is the interview within the interview. You have 10 to 15 minutes to show a room of strangers — often a principal, a department head, and sometimes actual students — what you can do.

Most candidates overthink the content and underestimate the structure. Here's what actually matters.

What Principals Are Watching For

They're not evaluating your lesson plan. They're watching how you run a room.

Presence and pacing. Do you control the energy of the room? Do you move through transitions without losing anyone? Do you notice when students disengage and redirect?

Clarity of instruction. Can you explain something complex in a way a stranger (the panel) can follow? Clear directions, one step at a time, no assumed context.

Student interaction. Do you call on students by name (if you've been given names)? Do you check for understanding rather than just asking "does everyone get it?" Are your questions open enough to generate thinking?

Adaptability. Something will go wrong. The room will be quiet. A student will give a wrong answer. A fire alarm might go off. How you handle that is part of the demo.

Your actual lesson plan is a prop. The demo is about you.

The 10-Minute Structure That Works in Any Subject

Keep it simple. Principals have seen elaborate demos fall apart because the teacher ran out of time or lost the class in a complex setup.

Minutes 1-2: Hook

Start with something that creates immediate curiosity or engagement. A question with no obvious answer. A short image or object. A claim that's counter-intuitive. Something that makes the panel lean in.

Minutes 2-6: Direct Instruction

Teach one thing. One concept, one skill, one idea — not three. Use the board or your display. Model your thinking out loud. Pause and ask a question every minute or so to keep students active.

Minutes 6-9: Guided Practice

Have students do something with what you just taught. A short problem. A pair-and-share. A quick written response. This is where you circulate and check for understanding. It's also what separates a lecture from a lesson.

Minutes 9-10: Close

Ask a student to summarize. Give a one-sentence takeaway. Make the connection explicit: "Today we practiced X because..."

That's it. Don't try to fit more in.

Subject-Specific Ideas That Work Well in Demos

ELA / Reading: Pick a short poem or a single paragraph from a text. Read it together, then ask: "What's the author doing here that you wouldn't expect?" This generates discussion, lets you model close reading, and works without any prior knowledge of the class.

Math: Choose a concept with a visual proof — fractions, geometry, probability. Build the understanding from a concrete problem, then show the abstract version. Estimation problems work well because every student has an entry point.

Science: Observations work beautifully. Bring in a physical object or use an image. Have students make predictions before you explain anything. The predict-observe-explain structure is one of the cleanest demo formats there is.

Social Studies / History: Use a primary source — a short quote, an image, a political cartoon. Have students interpret it first, then contextualize. It shows you value historical thinking, not just facts.

Writing: Have students do a 3-minute quick-write on a prompt, then share out. You demonstrate how to give brief, specific feedback to a student response. This shows your feedback habits, which principals care about.

How to Prepare Without Overbuilding It

You don't need a 20-slide deck. You need:

• One clear objective (write it on the board)
• One hook
• Materials for the practice portion (a handout, a problem on the board, a question to discuss)
• A way to close

Practice the first 2 minutes out loud at least five times. The hook is the hardest part to deliver cold.

One More Thing

Panels are rooting for you. Most principals doing hiring interviews genuinely want to find someone good. The demo is high-stakes, but it's not adversarial. Show them what you're good at, recover cleanly when something doesn't land, and you'll be fine.
