This is for those of you who are debating whether you should purchase this book: This book is more than I'd hoped it would be, especially for only $11. For each activity, there is also a lesson that tells its relevance. I was expecting maybe a 50 page "workbook" type activity guide, but this one has 173 pages, and isn't formatted like a workbook at all. Also, the maps in the book are very detailed and easy to read - and easy for my kids to understand. The pictures are in black and white, which is rarely any fun for kids, but for $11, I think I've gotten my money's worth. :)
