Taking the Guesswork out of Spelling...at HIGH SCHOOL!

Spelling is one of those things we’re expected to teach… but we’re not always shown how to teach it - especially when you're a high school teacher. We expect students to get better at it. We correct it. We comment on it. But when it comes to explaining why something is spelt a certain way, it can feel a bit less straightforward. Spelling at high school - let's go!

And then there’s all the terminology. Phonology, morphology, orthography. You hear it, you sort of know it but turning that into something teachable in a classroom is a different story.

I remember a student asking why a word was spelled the way it was, and realising my explanation wasn’t as clear as I wanted it to be. Not because I didn’t understand it, but because I’d never really had to break it down in a way that made sense for someone else.

That’s the thing with spelling. It isn’t random, but it doesn’t always feel logical either. It’s a system. If students don’t understand that system, they end up guessing.

Why spelling can feel hard to teach

Part of the issue is how spelling tends to sit in the background.

Students are often expected to “pick it up” through reading and writing, but that only works for some. Rules can feel inconsistent, and without a clear framework, it’s easy to fall back on word lists or quick corrections that don’t always stick.

As teachers, you can spot the error straight away but explaining it in a way that actually helps the student improve next time is a different skill.

The good news is you don’t need to change everything. A few small shifts can make a big difference.

A few practical shifts that make a difference

1. Move away from memorising word lists

Word lists aren’t useless, but on their own they don’t always lead to long-term improvement.

If you shift the focus to patterns instead, things start to click. Students begin to see how words are built and how they connect, which makes spelling feel a lot less random.

2. Use word families instead of isolated words

This is one of the simplest changes, but it’s powerful. Instead of teaching words in isolation, group them:

• sign → signal → signature

• act → action → react

It helps students see that spelling is tied to meaning, not just sound, which is where a lot of confusion comes in.

3. Build spelling into writing, not just separate tasks

Spelling improves much faster when it’s part of actual writing, alongside focused practice.

This doesn’t need to be a big extra task. It can sit alongside the work you’re already doing. For example:

• a quick editing focus at the end

• a reminder to check for one specific pattern

Spelling skills develop when students have regular opportunities to revisit and apply the same ideas. A single activity can introduce a pattern, but it’s continued use that really makes the difference.

4. Focus on one or two things at a time

It’s tempting to correct everything, but that usually backfires. If students are faced with too many corrections at once, it’s hard for them to know what to focus on.

Choosing one or two patterns and revisiting them regularly makes progress much more visible.

5. Make the thinking behind spelling visible

Good spellers aren’t just accurate, they’re making decisions.

Getting students to explain their thinking can really help:

• “That looks right because I’ve seen that pattern before”

• “I think it links to this word…”

It turns spelling into something active rather than just guess-and-check.

None of this requires a huge shift, but it helps to have a clear structure behind it so ideas can be introduced, revisited, and applied over time. When spelling is broken down into manageable parts, it becomes much easier to teach consistently and come back to.

If you’re looking for something that pulls these ideas together, we’ve created a spelling resource that focuses on patterns, word structure, and strategies students can actually use in their writing. It includes ready-to-use slides, handouts, and teacher notes, so you can dip in, revisit key ideas, and use what works for your class.
