This whole series is a very creative way to teach students language arts/grammar. This particular book acts as a hook to teach students nouns. It could also be used as a fun way to revisit nouns. Many people do not enjoy being taught the same lesson. This book would be great to ensure the students know what nouns are whether they have previously learned it or not. I would use this in a 1st-3rd grade classroom. The activities could be more geared to the older ages if they needed to be. One activity could be that the students become noun detectives. Each student could be given a magnifying glass that they use to find their nouns. Another activity that could be used for higher grades even would be to ask the students to stand every time they hear a noun. This requires the students attention and it will allow them to be interactive with the book.
