The DinaMath series of text books was designed to respond to the failings     of the   modern   American   math   curriculum   and to provide parents with a     supplement (or a replacement)   to   ensure   that   their   children   learn basic     mathematics   well enough   to   succeed in algebra,   trigonometry, and calculus.     A good knowledge of   arithmetic is essential for these advanced subjects; also,     arithmetic is the part of math that is most useful in everyday life. Clear, coherent     explanations,   plentiful   examples and practice   problems, and amusing pictures     make these books useful and fun for students.             The first book in the series, "Mathematics for Little Ones" is written for a     very young   child who has just   learned to   count.   It covers basic arithmetic,     starting with counting up to 20 and to 100, going on to simple calculations with     one-digit numbers, and progressing to addition, subtraction, multiplication, and     division of whole numbers of any size. The multiplication' table is covered, and     the student is encouraged to memorize it. Every topic is accompanied by word     problems; learning what the arithmetical operations mean, and   where to apply     them, is as important as learning how to perform them.             The book consists of two parts: a   Textbook  and a   Workbook.  The     textbook   contains   explanations,  examples, and a few practice problems for     each lesson. The workbook contains problem sets to accompany each lesson     and answers to all the problems.
