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. This set is designed to be used during the first half of the year. The teacher's guide features objectives, materials needed, and a list of page numbers; teaching instructions are provided in a step-by-step, listed format that's incredibly easy to see and read. Reduced student pages are given with the correct answers overlaid. Brightly colored pages and cheery illustrations give kids a fun atmosphere to work in. This kit includes: Math in Focus Teacher's Edition Kindergarten A, 171 pages, indexed, spiralbound, soft front-cover, hard back-cover. Math in Focus Workbook Kindergarten A Part 1, 67 pages, softcover Math in Focus Workbook Kindergarten A Part 2, 43 pages, softcover.
