Chunk and Chew ensures that students are not inundated with input from the teacher without being given appropriate time to process information. By following the Chunk and Chew strategy, teachers deliver their lessons in small "chunks" giving students time to "chew" the information either individually, with partners, or in small groups. Follow this simple rule: For every 10 minutes of teacher input, students should be given 2 minutes to process information. (This is known 10 and 2). Time frames vary and should be adjusted according to language proficiency and grade level of the students. When students are aware of the strategy of the Chunk and Chew technique, they will anticipate the processing time and let the teacher know when they have reached their limit on input.
