The all-around differentiated offer features a tried-and-tested concept in the student volume. It includes differentiation in three phases, graduated exercise sequences, and repetition at two learning levels. The tasks are competency-oriented, and student CD-ROMs are available in the existing student volumes 5 to 9. New for student volume 9 is a student CD, along with worksheets that offer three difficulty levels. References in the student volume link the book and CD-ROM, while learning game modules provide playful tasks and puzzles. Workbooks are available for individual support and challenge. A diagnostic test allows students to check their competencies, and evaluation enables students to assess their own tests while teachers analyze strengths and weaknesses. Support worksheets include basic tasks, extension exercises, and challenge worksheets with more difficult tasks. Solutions are provided on teacher CD-ROMs, along with suggestions for editable class tests and task sheets with dynamic content.
