This is such a fun book for kids who are learning about homophones, or for kids who are learning to read. My niece and I spent some time with this book today, and we had a lot of fun comparing the words and discussing how interesting it was that words that sound alike could be spelled differently and have different meanings.
The text in this book is not too difficult, which I think really enables new readers (or spellers) to spend time studying the words and comparing and contrasting them. The pictures are helpful in interpretation of the words, and I noticed my niece's eyes darting back and forth between the pictures and the words on the page. Just a great tool to use in teaching about the English language. I could also see it being useful for ESL students.
