If you are looking for a good introduction or a mini-unit study on the state, then this is ideal. In order to have a complete state study you will need to add to the information provided here, especially when it comes to the older children. What material is provided is very good, just doesn't make for a complete unit study on the state. It is easily adaptable and built on in order to achieve a more thorough study of the state in many ways.
