I have gained a lot of ideas from looking at what TEFL teachers are doing. Often there are some really creative ideas that they use. One site that I would recommend is www.teflclips.com from which I took the idea for the cat conversation activity. This is a great activity for the end of the personal identification topic, especially at KS4 when they can add lots more ideas in usgin previously learnt language. The video is great! The PowerPoint below is to help develop the activity as part of a Spanish lesson.
