Using an Interactive Whiteboard to Teach From Your Own PDFs

Most interactive whiteboard tools start with a blank canvas. But teachers rarely teach from a blank canvas — they teach from a worksheet, a past paper, a textbook page or a diagram they've already prepared. The interactive whiteboard that actually fits a lesson is the one that lets you teach on your own materials. Here's how to use ClassKite's smart board teaching as an interactive whiteboard built around the PDFs you already have.

Open your page, not a blank board

Upload a PDF and present it full-screen on the display. It opens exactly as it prints — nothing reformatted, nothing stripped out — so the page your class sees is the page you prepared. Slide decks work too; just export them to PDF first.

Write on it the way you'd use a whiteboard

With PDF annotation you have a full ink toolbox: pen, calligraphy ink, highlighter, shapes, text boxes and sticky notes. Work through the page live — underline the key step, sketch the diagram, model the method — exactly as you would on a physical board, except it's layered over the real material.

Keep every screen on the same page

What makes it interactive rather than just a projected PDF is that students can follow along on their own devices:

• Live stroke streaming sends your annotations to student screens as you write.
• Follow-me page sync moves everyone to the page you scroll to, so nobody gets lost.
• Push practice in a tap — go from explaining to a quick check without switching apps.

It runs in the browser, so it works on a smart board at the front, a laptop, or a tablet.

Annotate once, reuse next time

Your marked-up copy is kept as you go (and survives a dropped wifi connection); tap Save to store it. Next year, open the annotated version instead of starting from a clean page — the worked example you built live is still there.

Try it free — upload a PDF and teach your next lesson on it.

Before your first lesson on the board

Five minutes of checking beats discovering something with thirty students watching.

• Open the file on the actual display you will teach from, not just your laptop. Board resolutions vary, and it is worth knowing how much of the page you get.
• Check the page you plan to start on. Scrolling to page 14 in front of the class is a slow minute; opening on it is not.
• Have one student device joined so you can see what they see. Follow-me sync and live strokes are much easier to trust once you have watched them arrive.
• Know your file size. Very large scanned PDFs are slower to open than exported ones; free and paid plans allow different sizes and page counts.

How this differs from a traditional interactive whiteboard

An IWB app usually gives you an infinite blank canvas and a library of shapes, and expects you to build the lesson inside it. That is a different job from the one most teachers actually have.

• Page-first, not canvas-first. You teach on your own material, in its own layout. There is no infinite canvas to get lost in and nothing to rebuild.
• The annotation belongs to the page. Your ink is saved against that page of that file, so reopening the lesson brings back the worked example exactly where it was.
• It is not a drawing package. Pen, calligraphy ink, highlighter, shapes, text and sticky notes cover teaching; it is not trying to be a design tool.
• Students are participants, not spectators. The same page they are watching can become practice they answer, without changing app.

Making a worked example worth keeping

The reusable part of live teaching is the worked example — the one you build stroke by stroke while explaining. A few habits make it worth reopening next year:

• Work in one colour for the method and a second for the correction; a year later you will still be able to read which is which.
• Leave the wrong turn on the page if you took one deliberately. A crossed-out first attempt teaches more than a clean answer.
• Save at the end of the lesson while the reasoning is fresh, rather than trusting you will tidy it later.

Frequently asked questions

Do I need a physical smart board?

No. ClassKite runs in the browser on a smart board, laptop or tablet. Any display at the front of the room works, and students follow on their own devices.

Can students see my annotations live?

Yes — your strokes stream to student screens as you write, and follow-me page sync keeps everyone on the page you're teaching.

What file types can I teach from?

PDFs. If your material is a slide deck or document, export it to PDF first and it will open as it prints.

Which plan do I need for this?

Teaching from your PDFs with live annotation works on the free plan. Larger files, more pages and unlimited topics per class come with the paid tiers — see the comparison.

Can I teach from a PowerPoint?

Export it to PDF first and it works exactly like any other file. ClassKite renders PDFs; it does not convert slide decks itself.

What happens to my annotations if the wifi drops?

Your ink is kept locally as you work and syncs when the connection returns, so a dropped connection mid-lesson does not lose the board.

Can I annotate on a tablet instead of a smart board?

Yes — it runs in the browser on a smart board, laptop or tablet. A stylus makes handwriting easier, but a finger or a mouse works.

Do students need the same file?

No. They see your page and your annotations streamed to their own screens; there is nothing for them to download or open.
