This Valentine’s Day Code Breaker worksheet is a perfect way to practise vocabulary while keeping learners engaged and curious.

In this activity, students solve simple codes to reveal Valentine’s-themed words and messages. The task encourages logical thinking, careful reading, and vocabulary recognition — all wrapped in a playful, seasonal format. It works well as a warm-up, a short filler activity, or a light revision task before a speaking exercise.

The worksheet is suitable for ESL learners at lower levels, but it can easily be adapted for stronger students by adding follow-up questions or asking learners to create their own coded messages for a partner.

How you can use it in class:

• individual work or pair work
• fast finishers activity
• Valentine’s Day lesson warm-up
• homework or online lesson task
