The stated learning gap is difficulty decoding unknown words. The unit Sign of the Beaver was chosen because it requires the students to read from the chapter book. The three through five grade cluster Reading content standard tells us that the student will develop the reading skills necessary for word recognition, comprehension, interpretation, analysis, evaluation and appreciation of the written text. I chose the Sign of the Beaver unit because it challenges my fourth grade students to use the Internet to explore the topic based on this chapter book to improve their decoding skills as addressed in teacher pre-survey question number 22.
