Query: Poor grammar, weak vocabulary, negative school message

If I could give these books less than one star, I would. These books are good for a student who is struggling to be motivated to read but otherwise I am sad that these have become so popular. There are SO many WONDERFUL children's books available to encourage kids with and these lack so much of what kids should be getting in elementary school. The grammar is very poor. There is almost no vocabulary enhancement. To most elementary kids it has not occurred to them to have a negative feeling about school and these books put negative ideas in their head right when you want them to be building a foundation that school is an important, safe, encouraging and positive place. In my opinion, skip these.
