This free A2–B1 grammar worksheet helps students practise the difference between because and because of.
It is designed for adult English learners, ESL students, EFL students and English teachers who need a clear, practical grammar lesson for class, homework or self-study. This is a common grammar problem at lower levels because both forms give a reason, but they are followed by different grammar structures.
Students practise using because + subject + verb to give a reason with a full clause. They also practise using because of + noun, because of + noun phrase and because of + -ing to give a reason without a full clause.
The worksheet helps students understand the difference between examples such as I stayed home because I was tired and I stayed home because of the rain. It also focuses on common sentence patterns such as because it rained, because of the rain, because she missed the bus and because of missing the bus.
The PDF includes a grammar focus section, because vs because of exercises, choose-the-correct-form practice, sentence matching, correction tasks, mini-dialogues, mixed gap-fill practice, sentence rewriting, speaking practice, writing practice, vocabulary practice, an error-checking challenge, a useful reminder table and a full answer key.
This worksheet can be used in one-to-one lessons, group classes, online English lessons, adult ESL lessons, EFL classes or as independent grammar practice.
