I am so impressed by this book! The curriculum is so fun and well thought out, my 4-year-old is having a great time doing all the activities! I think we’ll be able to use this for several years, and each summer she’ll learn more complex information as we do the activities again. It is written as though you are doing this with a class, so it would be great for camps and classrooms, but also works fine for one kid. Highly recommend, great quality and great value for the money!
