In, On, At: A Helpful Guide To Preposition Rules in ESL

Experienced ESL teachers will say there are no rules to using prepositions in English.

Well, that’s not entirely true.

After years of seeing my students struggle with prepositions in, on, and at, I’ve found a brilliant way to teach them that really works.

There are rules, and the rules can be learned.

There’s no reason for beginner ESL students to have to grope around in the dark trying to figure out which preposition to use.

One reason prepositions are challenging is that they don’t translate well between languages. Students often discover that the preposition they would use in their first language isn’t the one English speakers use. If your students are thinking in their native language, they’ll translate most prepositions incorrectly.

Not Why, But When.

When my students are studying prepositions in, on, and at, one of the first questions they ask me is, “Teacherwhy?

Why do we say on Monday, but in May?

I always cringe when I hear this question. Not because I can’t answer it, but because it’s not the question they should be asking.

Instead of why, let’s focus on when.

So that’s what I did.

Grammar books tend to teach prepositions one at a time, in a painful attempt to have students memorize them as they occur.

Nobody has time for that.

Instead, I’ve developed a system of organizing prepositions by topic.

I created a resource and visual chart for teaching prepositions in terms of topic: time, place, transportation, and media. There may be more topics out there, but these four a a great place to start.

Rather than relying on traditional practice where students guess the correct preposition, I test them on the rules of preposition usage by topic.

When you organize prepositions by topic, students begin to see patterns emerge. As a result, choosing and using prepositions gets easier.

Want to know how it works? I’ll tell you. Or you can jump right to the visual chart. You’ll understand what I’m talking about at a glance, and your students will, too.

  1. This information is really interesting and helpful 🙂 I speak spanish, so these prepositions are kind of difficult for me. Thank you!

    • I’m so glad it helped you! I’m learning Spanish, and it’s the same for me- with “para” and “por”. 🙂
