I read this book as both a homeschooling parent and a math teacher/tutor and homeschool consultant. I would definitely recommend it to homeschoolers and other parents looking to engage their child with math through games. As a math educator, I'd seen some of these games before in other books but was happy to find many more that I'd never played and which use simple materials. I've tried a couple of them with my own kid and we enjoyed them and will try more, but she is at the upper end of the age/skill range for these games and I think we will get more out of the upcoming books in the series with multiplication and fraction games.
I think my favorite thing about this book is the perspective on teaching math that is communicated. I appreciate the focus on problem solving and logical reasoning, on playfulness, and on communicating and enjoying math together. The games are intended to be fun and to get kids (and adults) thinking and building their number sense, not just to practice a skill. I also enjoyed that the history of the games is given and that there are variations to try for many of them.
I did find the format of this book rather text-dense for a book of math games. This made it harder to look at a game quickly to remind myself of how it is played before/while trying it out with my child. I'm not sure what the solution is...Maybe numbered steps? I did find the illustrations helpful.
I certainly encourage giving this book a try if you are looking for math games for younger children.
