You are able to dramatize the information in big, even colorful letters or diagrams that the students can take home as a mental picture. Actively involve students and invite them to do the same. There may be time when you won't have the answer to the student's question. Always follow through and do your best to answer the student's questions in a timely manner. Stop the tutoring session from time to time so that students can summarize and reflect on what they have learned thus far.
Students can summarize orally, in writing, or with the use of diagrams or pictures.
