Rubric Block

Plot Summary Accuracy

Teacher looks for: A clear, concise summary that covers all core plot points and character arcs without extra filler

How to meet it: Stick to the key takeaways and timeline activity, and avoid inventing or overstating minor plot details

Theme Analysis Depth

Teacher looks for: Specific links between character actions, plot events, and core themes, not just vague statements

How to meet it: Use the theme tracking activity from the study plan to tie every theme claim to a concrete character choice

Historical Context Connection

Teacher looks for: Demonstration that you understand how real WWII events shape the novel’s plot and characters

How to meet it: Map character timelines to real historical dates using the study plan’s first step, and reference those dates in your analysis

Timeline Sync Activity

Use this activity to connect character choices to real historical context. Draw two columns on a sheet of paper, one for Marie-Laure and one for Werner. List 5 key dates for each character, then add a third column to link each date to a specific WWII event. Use this before class to contribute context-rich comments to discussions.

Moral Choice Tracking

This activity helps you build evidence for theme analysis. For each main character, list 3 moments where they must make a difficult moral decision. Next to each choice, write which core theme it reflects (moral integrity, power of science, etc.). Use this before essay drafts to gather concrete evidence for your thesis.

Symbolism Breakdown

The novel’s recurring objects carry symbolic weight. Identify 2 objects or images that appear multiple times. Write one sentence explaining what each object might mean to Marie-Laure, and another for Werner. Use this to add depth to your essay claims or discussion points.

Common Mistake Avoidance

One of the most frequent errors students make is ignoring the dual timeline’s purpose. The novel alternates between characters to highlight shared humanity across enemy lines, not just to tell two separate stories. When writing or discussing, explicitly link timeline shifts to this thematic goal. Double-check your notes to ensure you’re analyzing both characters equally.

Class Discussion Prep

Come to class with one prepared discussion question and one piece of evidence to support your answer. Use the sentence starters from the essay kit to frame your question, and reference your timeline or moral choice activity for evidence. This will help you lead targeted, insightful conversation.

Essay Draft Prep

Start with one thesis template from the essay kit, then customize it to your specific focus (theme, character, structure). Use the study plan’s evidence sheets to fill in the body paragraphs of your outline skeleton. End each body paragraph with a sentence that ties back to your thesis. Use this before writing a full essay to save time and improve focus.
