"Hi, Clouds" is a book about what you can see in the sky. It starts out with children saying `hi' to clouds: thin, fat, white and gray ones. It then proceeds to clouds that are shaped like animals and objects (including some really silly ones like a dog, a frog and a clock?!)
There are about 27 vocabulary words, including: asleep, dragon, sheep, wagon, covered and clock (among the hardest). Despite the variety of words and the fact that they are not the simplest kinds of words, I think that this is a good beginning reader. In fact, I think that you could use "Hi, Clouds" with pre-reading children. [I am using it like this for my almost 4 y.o. son.]
The format is so simple (one line per page), and the pictures so clearly give clues to what is written that any child can probably `pretend' to read it.
An example follows (from six pages) so you can judge for yourself.
Hi, fat cloud.
Hi, thin cloud.
Hi, white cloud.
Hi, gray cloud.
Don't rain, cloud.
Three Stars. [B-]. Conceptually simple (there's not much of a story here), this book might just be right for your beginning reader. Or pre-reader who wants to `practice' reading.
