Thanks for the wonderful ideas! We do like Fly Guy, and I checked out some Bad Bears books which look adorable. I will look into the others, too!
CraftyHomeschool, yes, the boys do sound a lot alike! Our favorite books by far have been the Cork and Fuzz series by Dori Chaconas. They are SO cute, and funny. We're also reading some Tom and Ricky books, although they don't have many illustrations. The books are almost entirely "decodable," and use really common words. There is a lot of repetition which is great, but they're also pretty good mysteries! You can buy them really cheaply on Amazon.
Lecka, I'm not sure if there are phonemic awareness issues. He has no trouble saying a word in sounds, so on the one hand it doesn't seem like that's the problem. His spelling is not very good though. He can spell a word aloud much better than he can write it. When he reads, it's as though he doesn't see the separate letters in a word unless I specifically tell him to look closely - they are just a big mush. Lindamood-Bell was an absolute disaster for him, and it didn't really help much at all. His reading specialist at school told me we just need to abandon any sequential teaching method and instead teach him sight words, prefixes and suffixes, and how to visualize and guess the word accurately from context. I'm with her most of the way, but I still want him to sound out words... We are doing repeated oral reading, choral reading, typing, and lots of sight words this summer. I think Davis would help a lot, but he doesn't like building words with clay, with Legos, writing with chalk or any of that. He just wants to be a ninja and that's it! :-)
Thanks again!!
