What Is Grammar Practice?
Grammar practice online is a practical way to build accuracy in written English. Instead of passively reading grammar rules, students actively find and fix errors, which makes them apply each rule to a real sentence.
This free grammar practice tool presents sentences with common grammar mistakes across five core categories: Subject-Verb Agreement, Punctuation, Capitalization, Tense, and Homophones. Students type the corrected sentence, tap the error, or pick the right version, and receive instant feedback with a clear explanation of the underlying grammar rule.
Whether you are a teacher looking for interactive grammar exercises for your classroom, an ESL learner practising English grammar fundamentals, or a student preparing for a grammar quiz, this tool provides targeted, self-paced practice with no sign-up and no cost.
Why Practice Grammar with Error Correction?
Rewriting a sentence correctly asks more of students than recognising the right answer in a list. They have to spot the error, recall the rule, and apply it in context. That is why typing the correction is the default here, with tap-the-error and pick-one modes for younger students or quick whole-class rounds.
This tool covers common errors: homophones like their/there/they're and your/you're, subject-verb agreement with tricky subjects, irregular past tenses, and punctuation mistakes like comma splices and missing apostrophes. Pair this tool with our Spelling Test Maker and Reading Level Calculator for a complete literacy toolkit.
