The first conditional is used to talk about real and possible situations in the future. We often use it to express plans, promises, warnings, or predictions, such as “If it rains, I’ll stay home.” Learning how to form and use first conditional sentences correctly helps students communicate more clearly. In this article, you’ll find easy worksheets and exercises to practice the first conditional in a fun and practical way.
