A Tree is Nice is a book that received the Caldecott Medal Winner. Of course, the book is about trees. The vocabulary words from this book are: numerous, recreation, shelter, and necessary. Numerous means many. Recreation is something a person does for pleasure or fun. Shelter is a place that protects people or animals from the weather or keeps them safe from danger. Necessary means something is needed or very important. Isn’t it interesting than none of the vocabulary words appear on any of the pages of the book?
