At the end of the lesson, the students should take a few minutes to review what they have learned. Ask them to summarize the different types of serves and the rules for serving in volleyball. Encourage them to ask questions and provide any additional feedback. After the review, have the students go over their practice serve skills and demonstrate their mastery of the different serves. Ask them to explain the techniques they used and evaluate their accuracy. Finally, have the students reflect on their progress and discuss any areas that need more practice.
