How play-based language modelling supports early communication
When we think about supporting early AAC users, it’s easy to feel the pressure to ask questions or prompt responses. But real communication develops when we focus on connection — not correctness.
One of the most powerful strategies we can use during play is simply commenting as we go. In the Early Years Foundation Stage (EYFS), this is often called “running commentary” — narrating what a child is doing, seeing, or showing interest in, using simple, familiar language. With AAC, this means pointing to words on a board or device as you talk.
Let’s take the humble train set. A classic, open-ended toy — and the perfect setup for rich communication.
What It Looks Like
Imagine this:
You’re sitting beside a child pushing a train around the track.
You model:
- “go go go” (pointing to ‘go’)
- “fast train!” (pointing to ‘fast’ and ‘train’)
- “oh no!” as it crashes (pointing to ‘oh no!’)
- “again?” when they put it back on the track
There’s no quiz, no test. Just shared attention, enjoyment, and accessible language.
Why It Matters
This approach builds:
- Vocabulary in real contexts
- Turn-taking without pressure
- Understanding of language through repetition and routine
- Motivation because the child is in control of the play
It’s also a perfect fit for modelling without expectation — showing language on a device or board without requiring the child to use it in return.
Using the Train Boards
We’ve created two printable train-themed low-tech AAC boards to support this kind of play:
20-Cell version for early communicators

30-Cell version with extra fringe and question words

These are designed to sit alongside the Super Core 30 vocabulary — but they work just as well in any play-based setting.
Summary
Trains aren’t just toys — they’re tools for connection. And AAC doesn’t have to mean formal sessions. It can be as simple as sitting down, following a child’s lead, and saying what you see, with symbols to support it.
In short:
Just play, point, and talk. The words will follow.
