Instead of a normal gap fill exercise, one of the students, whose home language is not English, chooses 10 words from a text and translates them into his/her home language. That student then reads the text aloud while other students who are listening guess the words based on the context.
This activity can also be done in pairs or small groups. The speaker could give hints and examples, say the rest of the sentence, paraphrase if needed. After the listener(s) find all the words students could change roles and do the same thing again. They can choose whatever words they want – hard, easy, interesting, fun. The objective is the thinking and talking about the key content and newly encountered knowledge. Example taken From Year 9 Exploring Science course book:
