Phrasal verbs are an important part of the English language but something that students may struggle to learn and understand. By introducing only a small number of similar phrasal verbs at a time you will greatly improve the chance that your students will retain the information. A variety of practice activities are also important so that students can demonstrate their thorough understanding of the material. An example of phrasal verbs you might want to introduce together are back down, back up, and back out because they all start with the same word and include a direction related word. Another approach may be to choose phrases that use the same second word as they may be less easily confused. Your approach and the phrasal verbs you choose to cover should be based on your students, textbooks, and other course material.
