Hello. I am excited about TOG. I am just wondering. This fall when we start year one, I will be teaching my 9yr old son and 6yr old son. My 9yr old son would have been going into 3rd grade. He is a strong reader and can read on his own. I will be starting Kindergarten with my 6yr old son. I am looking for advice regarding my 9yr old. I have a set of twin 3yr olds son/daughter as well, so I am wanting him to be able to read the reading assignments on his own. Do you think the UG readers would be too hard for him? Should I just stick with the LG for the both of boys? I like the list of UG books. I am torn. Any suggestions?
