We use conditional language to discuss hypothetical situations and what the outcomes may be. We often do this when planning something. These sentences often contain the conditional word if. There are four different types of conditional sentences that you will come across. We will use these forms for different purposes and to maintain proper grammar and mechanics in our sentences. Zero conditionals are used for present and real situations. They are used when the clause and main verb tense are both in simple present form. First conditionals are used for real future situations. You will find this form of usage when the clause verb tense is in the simple present and the main clause verb tense in the future form. Second conditionals are used for present or future imaginary situations. Third conditionals are used for past imaginary situations. These forms can also be presented in a mixed setting. Punctuation is the key for these types of sentences, but a simple rule applies. When the if-clause paves the way for the main clause, place a comma after it. It the main clause leads the if-clause, no need for punctuation.

These activity sheets define the five different types of conditionals (zero, one, two, three, and mixed) used to express circumstances, desires, and more. Your students will learn how to identify these conditionals by marking given phrases, writing their own, choosing the correct verb tenses to complete the conditional, etc. Where definitive answers are required, answer keys have been provided for the instructor, but please note that in some activities, the students’ answers will vary. Teacher Tip: Discuss how conditionals can also reflect different moods in English, such as the subjunctive mood. (Note: this can get confusing for beginning students.)
