Based upon the Singapore method of teaching mathematics, Math in Focus features a problem-based approach that builds on a concrete-to-pictorial-to-abstract progression. Within each grade fewer topics are taught, but at a more in-depth level; visual representations, modeling strategies, and a development of conceptual understanding, place value, and computation fluency help students to understand the "how" behind their exercises. The consumable student workbooks provide practice, assessment, and skill-development exercises. In the textbooks, cheery illustrations and easy-to-understand lessons give kids a fun atmosphere to work in. Each chapter includes "Put on Your Thinking Cap" problem solving exercises and a chapter review/test. The first semester of second grade (2A) helps children work on numbers, addition, and subtraction to 1,000; bar models with addition & subtraction; multiplication and division; metric measurement; mass; and volume. The second semester (2B) covers mental math; money; fractions; measurement; time; multiplication tables 3 & 4; picture graphs; lines; shapes; and more. Grade 2.
