It's hard to talk about friends if you don't use the word
  AND.
 I feel the concept of friendship is a nice place to also systematically introduce our language-challenged children to use this very important conjunction.  I went to the tried and true website,
 Tarheel Reader, and created a 'Friends' book.  The pictures on that site are delightful, and I then downloaded the book and added a page of icons along with a sentence strip.  I don't know about your students, but mine, with the help of my books, are clearly developing one-to-one correspondence with speech and written words.  Yea!!!!! This growth in literacy skills is wonderful to see!    I think adding a compound subject is a logical way to expand their simple sentences!
I just created this book, and haven't tried it out yet on the little guy I have in mind, but I can't wait!
I'll post a picture or two here when I do. 
You can expand this concept by having the kids make their own 'friends' book--use digital photos of classmate pairs.   Who does your child want to pose with?

Happy Mother's Day to everyone!  I'm blessed to have a wonderful family with mothers all around, young and old.
