- Ask students to keep this list in mind while they listen to the first mystery in Encyclopedia Brown, Boy Detective
Activities
Part One
- Read aloud the first chapter of Encyclopedia Brown, Boy Detective “The Case of Natty Nat” pages 1-11 to the class modeling appropriate voice inflection while reading.
- After reading the chapter, return to the list created by the class. Review items listed and determine if each item is present in the mystery just read aloud. Pay particular attention to the items that were mentioned by more than one group. Then ask the class if there are any other things that should be added to the list. Keep this list posted in the classroom. After reading any other mystery, allow students to add items to the list.
- Talk with students about the characteristics usually present in mystery stories concerning the content and the story structure. To encourage analysis of the content of a mystery, discuss the Mystery Worksheet by talking about each of the terms listed and asking the students to listen for information in the second chapter of Encyclopedia Brown.
- Have the students take turns reading aloud from chapter two “The Case of the Scattered Cards” pages 13-21. Encourage the students to use voice inflection while reading.
- After reading the chapter, use an overhead transparency of the story map Mystery Worksheet to list items from the story, begin listing ideas or words from the story in each of the categories. Encourage the students to help respond to each category.
- After most of the categories are completed as a class ask the small groups to discuss the clues and try to come up with possible solutions. Share these solutions with the class.
- Place the overhead transparency of page 103 and share the solution with the class.
- Ask the small groups to read the next mystery “The Case of the Civil War Sword” pages 23-29.
- Have the groups complete story map Mystery Worksheet together and discuss possible solutions. Share these with the class.
- Share the overhead transparency of page 104.
- Pass out copies the multiple choice questions for chapters 1-3. Read each question to the class. Model thinking strategies and the process of elimination to demonstrate how the students should reach the correct answer. Also make sure and have the students look up sections of the book when it would help to make sure of answers. Mark down page numbers and paragraphs to support answers eliminated and/or answers selected.
- Continue the steps described above until you have read and discussed all of the book.
Part Two
