**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.
