Here is just a hint to help the kids improve their speaking skills. It can be used for speeches, but also for role-plays, in pairwork (talking about a selected topic), creative writing. I think it suits to any topic we could talk about. You can make up your own sample sentences as it suits your students - depending on their age, level and interests, of course. Basically, it can be used for all levels of English knowledge except for complete beginners.
