This unit is a printable worksheet companion for the chapter book Humphrey’s Playful Puppy Problem by Betty G. Birney. Humphrey's Playful Puppy Problem is a great introduction for younger students to chapter books. When I use this unit with my 2nd grade students, we read one chapter per day followed by my students using their books to complete the page, or pages, in this unit for the corresponding chapter. I like to use this unit to teach my students how to go back into their book to locate answers and practice writing those answers in their own complete sentences. This unit also reviews reading skills like problem & solution, making predictions, and determining character traits.
