Cambridge YLE preparation books scaffold vocabulary in an excellent way: they don’t only teach the words/expression, but guarantee that these lexical items are revised several times over the year. Before a progress test or before the final exam, you might find some revision lessons useful and – above all – fun. One engaging way to revise vocabulary is to play TABOO.
If you prepare kids for YL exams (Cambridge STARTERS, MOVERS, FLYERS), then you are well familiar with the official wordlist. However, it is sometimes difficult to keep track of the taught lexical items. With some textbooks, you don’t have to worry about anything: they teach and revise the requested vocabulary. On the other hand, if you teach classes without a textbook and/or with your own materials, you might find these Cambridge wordlists (Progress Checkers) useful.
