Everything you need to understand or teach Christopher Mouse by William Wise.
Christopher Mouse: The Tale of a Small Traveler is a juvenile fiction chapter book that chronicles the trials and triumphs of a white mouse named Christopher. The book is Christopher's diary, and he shares his first memories all the way up to his happy ending that may just end up getting even happier. But times are not always good for Christopher. As a small white mouse, he is at the mercy of humans who do not always have his best interest at heart. In this story, Christopher has plenty of interesting experiences, including a couple of near brushes with death at the paws of a menacing cat or the umbrella-wielding hands of two shrieking ladies. Through all his travels, Christopher learns a lot about people and about himself and he writes poetry to capture his feelings.
