I purchased the whole series two years ago for my kids. The series came with printable workbooks that the kids could do while I read. My kids are 9, 8, and 4 and they still love these books. My oldest two learn so much from the books and it reinforces the values and morals that we teach them. The books teach about taxes, laws, manufacturing, and truths that aren't taught in schools anymore. I encourage people to at least read 1 of the books before totally disregarding them. My kids are always asking if we can read another Tuttle Twins and it makes me happy as a parent to know that they enjoy the books and that they are learning so much.
