I don't think they have anything that old, but it might be worth a shot. If you have easy access to the titles let me know what they are and I will look to see if they have any workbooks.
Ah, seems that some of them I have aren't all that old like I thought; do things that have Macmillan (as WELL AS the McGraw-Hill name) on them apply? THe one I have in my hand is titled "Don't Forget to Fly" with a copyright of 1993. I think the others are here somewhere.... Ah, here's one that's fairly new. It's yellow, says Texas Edition on it with a picture of a racoon taking a bath with a rubber duck (at least, that's what it looks like... LOL). The only title I see says McGraw-Hill Reading; I'm quite sure it's a 1st grade book, and the copyright on it is 2001. I think the box with the majority of the stuff is outside in the shed; since it's dark and raining, I'll go find it tomorrow. LOL I know some titles off the top of my head, but I'm not sure which titles go with which publishers. I have another couple of books in the "Don't Forget to Fly" series, and some that I think are the same publisher but a different grade that are Native American looking in their cover art. I'll go grab that box tomorrow. Thanks so much for checking!
