Perspective Detectives Answer KeyTeacher Guide & Answer Key Perspective Detectives Key By Annie Barrows • Illustrated by Sophie Blackall • Chapter 2: The Science Fair Standards Aligned RL.2.6 • RL.2.1 • RL.3.6 Instructional Purpose: Chapter 2 establishes Bean's central motivation throughout Book 7: she resists incremental, small actions because she believes only a dramatic, groundbreaking invention will solve a crisis as huge as global warming. Question 1: Bean's Reaction to the Announcement Correct: B Correct Answer: B. She feels determined because she wants to invent something huge and save the earth. Perspective Rationale: Bean is not indifferent or scared; her personality is action-oriented and ambitious. She immediately thinks about making a breakthrough rather than avoiding the challenge. Question 2: Supporting Detail for Bean's Perspective Correct: C Correct Answer: C. Bean believes small actions are not enough and that she and Ivy need one big, amazing idea. Evidence Citation: When Mrs. Aruba-Tate encourages minor acts, Bean thinks to herself that little things are for little kids and won't stop the glaciers from melting. This directly sets up the book title: What's the Big Idea?. Question 3: Contrasting Mrs. Aruba-Tate vs. Bean Correct: A Correct Answer: A. Mrs. Aruba-Tate tells the class that every little bit helps, while Bean thinks only huge ideas matter. Contrast Analysis: Mrs. Aruba-Tate tries to reassure seven- and eight-year-olds so they do not feel overwhelmed by ecological disaster. In contrast, Bean refuses gentle reassurance because she thrives on drama and grand quests. Teacher Answer Key • Ivy and Bean: What's the Big Idea? (Book 7) Page 1 of 2 • Solutions Continued → ✓ Teacher Guide & Rubric (Continued) Chapter 2 Analysis Question 4: Bean's View of Emma's Poster Correct: B Correct Answer: B. Bean thinks making a poster is dull and ordinary because anyone can do that. Perspective Rationale: Bean views simple posters as lazy cop-outs. She expects a science fair entry to involve tangible power and real discovery. Question 5: Why Bean Looks at Ivy Correct: A Correct Answer: A. She knows Ivy shares her creative mindset and is the perfect partner for an extraordinary project. Character Dynamic: While other classmates pick ordinary ideas, Ivy is Bean's soulmate in wild imagination. Their immediate silent understanding demonstrates their bond. Question 6: Classroom Atmosphere Detail Correct: C Correct Answer: C. Different students shout out wild ideas, argue about solutions, and worry about melting ice caps. Text Detail: Annie Barrows depicts Room 2 bubbling with chaotic energy—boys proposing ice cubes or outer space, girls debating light switches, and Bean scheming. Detective Notebook: Scoring Rubric (3 Points Total) Short Response 3 Points (Exemplary) Clearly explains Bean's perspective (believes small actions won't stop global warming) AND cites a specific detail from Chapter 2. 2 Points (Proficient) Explains Bean's viewpoint accurately but offers vague or general story evidence without specific chapter details. 1 Point (Emerging) Mentions the science fair or Bean wanting to win, but does not explain why she rejects small ideas. Model Student Response: "Bean wants a big idea because she thinks small things like turning off faucets or making a poster won't stop the world from heating up. In Chapter 2, Mrs. Aruba-Tate says 'every little bit helps,' but Bean thinks little bits are not enough to save polar bears—she believes only an amazing, giant idea will truly work."

Marcus forgot that the zero in 30 belongs to the basic fact \(5 \times 6\), so he still needs to account for the factor of 10. The correct answer is 300." Differentiation & Extension Menu Targeted Intervention (Tier 2/3): Provide physical base-ten rods (longs). Have scholars count by tens: "10, 20, 30... 120" to see that 12 longs make 120. Scholarly Extension (Tier 1+): Challenge scholars to extend the pattern to hundreds: \(4 \times 300 = 4 \times 3\text{ hundreds} = 12\text{ hundreds} = 1{,}200\).
