In spite of a few flaws, the main one being the admirable but unlikely-to-be-attainable intent indicated by its title, "Help Your Kids with Math," this is an excellent visual reference material for mathematical concepts in its six key categories: numbers, geometry, trigonometry, algebra, statistics and probability.
The biggest problem I have with the book is its premise. My personal experience as a highly involved school volunteer/math lover is that parents who struggled with math themselves continue to do so as adults and aren't likely to be able to teach key concepts (beyond the basics) to their children, whatever the resource. I can imagine this would also be the case with this book, especially considering that, excluding Chapter 1 (Numbers), it contains a lot of relatively advanced math. Four specific concerns about the content are as follows: (1) New and, I believe, more logical, simplified and appropriate terminology for what used to be called "borrowing" and "carrying" for addition and subtraction, that is, the term "regrouping" isn't even mentioned (a simple "also known as `regrouping'" would have sufficed). (2) Although examples of the associative (p 161), commutative (p 19, 161), and distributive properties (p 19) are introduced, the properties are not named within the main text, glossary or index. (3) In the linear graphs section, "the equation of a straight line" is introduced (p 174-175), but the only example for graphing a line recommends plotting points (they use four). An example of a quicker method, involving determining the y intercept and then drawing a line through it with the correct slope should have been included. (4) When discussing divisibility by 3 and 9 (p 23, 60), the concept of a digital root should have been introduced.
