The document discusses using tasks and activities to support language learning for children. It describes tasks as the environment for learning and should be used to check understanding and evaluate learners. Tasks engage active learners and help make sense of activities, though teachers need to ensure real understanding. Demands on learners and support provided are important to balance. Tasks should break activities into clear language learning goals and manageable steps. Stages of preparation, core activities, and follow up help structure effective tasks. Balancing demands with appropriate support produces optimal language learning.
