Singapore Math Dimensions Math Workbook 8A

Workbooks are the essential supplements to textbooks as they give students the opportunity to practice applying new concepts. Workbook exercises polish analytical skills and help students develop a stronger foundation in math through repetition and variation.

Features & Components:

• Basic Practice: Simple questions that drill comprehension of concepts.
• Further Practice: More difficult questions that involve direct application.
• Challenging Practice: Questions that require synthesis.
• Enrichment: Questions that demand higher order thinking, analysis, and reasoning.

The answer key at the back of the book provides answers only. Worked Solutions (sold separately) contain fully worked solutions.

Note: Two workbooks (A and B) correspond to the two halves of the school year. Soft cover.
