Information about the title: Support Workbook. The support workbooks are specifically aligned with the workbooks containing interactive exercises. They include tasks with a lower level of difficulty on the same content to assist students with special educational needs. Information about the series: Mathematics is now also part of the Jo-Jo teaching materials collection. The consistent use of calculation strategies (such as transitioning to tens) guides children on a secure path to learning success and promotes reflective thinking. The fundamental principle of "first understand, then practice" helps prevent calculation problems. Jo-Jo Mathematics incorporates the well-known advantages of the other Jo-Jo teaching materials: intentional integration of learning strategies, clearly structured pages, recurring formats, clearly formulated tasks, differentiation tasks at three levels, and regular assessments of learning progress.
