I think that it is very important to include a book about how to deal with loss or grief to your bookshelf. You may or may not have students encounter the loss of someone or something in someway. Whether that connection being direct or indirect, it's gonna happen. This book is about the friendship of two polar bears. Gus and Ida learn that Ida is very sick. When Ida passes away, Gus is sad but quickly realizes that Ida may be gone, but she is never forgotten. This would be a good book to use when dealing with grief or loss within your classroom. Teaching that even though these people or this thing is gone, they or it will never be forgotten. Having the student recall happy memories with the subject could be a good activity to use within any grade.
