I love Saxon. some say it's hard or difficult to work with, but Math is aleays a difficult subject and as long as you are patient, it gets easier. Me 7 year old has caught on very quick to it. Im learning also as I go.
i bought this to go with saxon 3. so far we havent used it much with those lessons, but when we do my son is very excited. my boys enjoy playing with these pieces regardless and overall im happy with the purchase.
