The Side by Side Activity Workbooks offer a variety of exercises for reinforcement, fully coordinated with the student texts. A special feature of the Activity Workbooks is the inclusion of GrammarRaps for practice with rhythm, stress, and intonation and GrammarSongs from the Side by Side TV videos. Periodic check-up tests are also included in the workbooks. Side by Side Plus is a standards-based and grammar-based English language program for adult and young-adult learners. The program builds students' general language proficiency and prepares them for their life-skill roles in the community, family, school, and at work.
