learners master skills by practice, in a similar way to other skill like playing the piano or swimming. You can give them practice in the whole skill or in subskills. Learners can practise the skill of reading in a general sense by, for example, reading a whole text and then answering a question, or they can practise various subskills, such as guessing unknown words, scanning for particular information, or predicting what will come next. These subskills, like practising scales in music or learning the stroke movements in swimming, help with mastery of the whole skili.
To introduce a reading text about festivals, you could ask learner about their favourite festival in their country. To introduce a story the students are going to listen to, you could show learners a picture and ask them to predict the story. To introduce a lesson on writing postcards, you could bring postcards sent to you for learners to read. To introduce a discussion of childhood memories, you could show the class a photo of yourself as a child and tell them one of you own memories.
