The MAVA Math series believes that students should: have plentiful practice; work at their own pace; copy problems minimally; show appropriate work when needed; attack both short and long challenges; develop number sense and mental math; learn numerous strands of math concurrently; and use math books free of distractions and clutter. MAVA Math: Number Sense is primarily for students in grades one through five. The book provides a detailed Table of Contents outlining the skills on each of the 298 pages of math, offers over 11,000 problems, and gives multiple answer columns to do problems more than once. Pages contain math and only math. The book's extensive discussion of number sense philosophy as well as tips on how to use the book may be read in question and answer format in the Free Preview, continued in the Free Preview for MAVA Math: Number Sense Solutions. This companion book provides all answers as well as guidance for proper techniques. Please find all MAVA Math products at www.mavabooks.com.
