Dimensions Math Common Core is ideal for both classroom and home use for 6th-8th grades. Recommended for those who want a challenging Singapore Math® series from a country with a proven track record in math education. This series integrates pre-algebra, algebra, and geometry and includes some trigonometry and advanced math topics. Teacher/Parent involvement is generally required.

Each workbook is written as a supplement to the textbook to give students more practice in applying the concepts learned. Students may refer to the summary of the important concepts in each chapter of the textbook for a quick review before attempting the questions in the workbook. After completing the exercises, students will not only polish their own analytical skills, but also develop a stronger foundation in mathematics.

The questions in each workbook chapter are categorized into 4 parts according to the level of difficulty and the thinking skills involved:

  • Basic Practice: simple questions that drill comprehension of concepts
  • Further Practice: harder questions that involve direct applications
  • Challenging Practice: questions that require synthesis ability
  • Enrichment: questions that demand higher order thinking

These questions encourage students to think analytically, reason logically, use appropriate connections between mathematical ideas, and apply problem-solving skills in daily life situations.
