If and Then: Mastering All Four Conditionals for Class 8  

This comprehensive worksheet helps Class 8 students understand and apply all four types of conditional sentences — zero, first, second, and third. With matching, classification, verb transformation, sentence rewriting, and creative paragraph writing, learners build fluency in real and hypothetical scenarios.

Why Conditionals Matter in Grammar?  

Conditionals teach logical structure and consequences in language. Students learn:  
1. Zero: facts and general truths.  
2. First: real future possibilities.  
3. Second: imaginary present/future.  
4. Third: hypothetical past situations.  
5. Mixed: combining time references meaningfully.

What’s Inside This Worksheet?  

This worksheet includes five targeted exercises to strengthen conditional understanding:

🧠 Exercise 1 – Match the Halves  
Learners match conditional clauses with results (using all types). Example: “If you heat ice” → “it melts.”

🧩 Exercise 2 – Identify the Type  
Students classify sentences into Zero, First, Second, Third, or Mixed conditionals.

✏️ Exercise 3 – Complete the Sentence  
Using verbs in brackets, students write correct conditional sentences. Tenses must match the conditional type.

🛠️ Exercise 4 – Rewrite Correctly  
Learners convert sentence pairs into correct conditional sentences using appropriate structures.

📝 Exercise 5 – Paragraph Writing  
Students write a paragraph on the topic *If I could change one thing in the world...*, using at least three types of conditionals and underlining them.
