Error Hunter: Find and Fix Grammar Errors

Proofreading improves when learners have to identify a problem, propose a correction, and explain what changed. Error Hunter gives students a paragraph with hidden grammar errors, then lets them hunt on their phones before the class reviews the fixes one by one.

How it works

1. 1

   Choose a topic and difficulty to generate a paragraph with a set number of mistakes.

2. 2

   Students mark the words they believe contain errors and submit corrections on their phones during a timed race.

3. 3

   Accurate hunts earn points, with a speed bonus for students who find the errors; an empty or inaccurate hunt does not get a speed bonus.

4. 4

   The round can end when everyone has submitted. During review, the teacher steps through the paragraph with each error struck through, its fix, its type, and the number of hunters who found it.

Frequently asked questions

Can students submit a correction from their phone?

Yes. Students select the error words and provide corrections through their phone input. The teacher screen collects the race results for review.

Does an empty answer earn the speed bonus?

No. The speed bonus is available only for an accurate hunt, which requires students to find and correct the errors.

How does the answer reveal work?

The teacher can reveal errors one at a time or show them all. Each correction is visible in the original paragraph with the error struck through.

What if everyone finishes early?

The race ends once all active students have submitted. The class can move directly to the step-through reveal and discuss which errors were easiest to miss.
