The document discusses different types of speaking and writing activities that can give learners varying amounts of control and choice over the language used. Controlled activities, like fill-in-the-blank sentences, restrict language use and focus on accuracy. Freer activities, like writing an email, allow some prediction of language used and guide practice. Free activities, like roleplays, don't restrict language and focus on communication. The document also discusses reading and listening activity types and how they develop different skills through multiple choice questions, ordering pictures, or jigsaw tasks.
