Conditional Sentences ESL Grammar Activity

Conditional Sentences ESL Activity Preparation

Prepare a chart outlining the four main types of conditional sentences, including their structure and example sentences (e.g., If it rains, the ground gets wet for zero conditional).

Create a worksheet with incomplete conditional sentences for students to complete using the appropriate tense. Also, prepare a matching activity where students pair conditional clauses with their logical results.

Print a list of real and imaginary prompts (e.g., If I won the lottery… or If you heat ice…) for group discussion or writing practice. Use color-coded cards to differentiate between “if” clauses and result clauses to support visual learners.

Conditional Sentences ESL Activity Guidelines

Begin the lesson by reviewing the purpose of conditional sentences: to express real or imagined situations and their consequences. Present each type one by one:

  • Zero Conditional: If + present simple, present simple (general truths).

  • First Conditional: If + present simple, will + base verb (real future possibilities).

  • Second Conditional: If + past simple, would + base verb (imaginary situations).

  • Third Conditional: If + past perfect, would have + past participle (past unreal situations).

Provide examples and explain when each is used. Then, give students a worksheet with mixed sentences to complete or correct. For instance:

  • If I study hard, I ___ (pass) the test.will pass (First Conditional)

  • If he had arrived earlier, he ___ (catch) the train.would have caught (Third Conditional)

After checking answers, conduct a matching activity. Distribute “if” clause cards and result clause cards. Students must walk around the room and find their matching sentence halves (e.g., If it’s sunny tomorrow / we’ll go to the beach).

Next, move on to a creative speaking or writing task. Assign each student a prompt like If I were invisible for a day… or If I hadn’t missed the bus… and ask them to finish the sentence and explain.

Encourage students to use different types of conditionals in a conversation or a short story.

Follow-Up ESL Activities

As homework or a follow-up task, students can write a short paragraph or dialogue using at least three different types of conditionals.

Alternatively, play a conditional chain game (or other ESL Word Chain Games) in class where students continue each other’s sentences (e.g., If I had a dog, I would take it to the park… If I went to the park, I might see my friend…).
