Character Change in 'The Blue Marble'
Mr. Alvarez's fourth-grade class has 26 students. After reading a short story called 'The Blue Marble,' he asks students to explain how the main character, Lena, changes from the beginning to the end. In the story, Lena keeps a blue marble in her pocket and refuses to let her younger cousin, Mateo, touch it. When Mateo accidentally drops the marble down a storm drain, Lena shouts at him. Later she sees Mateo crying on the steps and gives him a smooth gray stone from her collection, saying, 'This one is lucky too.' Mr. Alvarez sorts four written responses. Response A says, 'Lena is mean and then nice.' Response B says, 'At first Lena won't let Mateo touch the marble. After it is lost, she gives him another stone and says it is lucky. That shows she is starting to think about his feelings.' Response C retells every event in order, ending with 'and that is what happened.' Response D says, 'Lena is sad because she lost her marble.' Mr. Alvarez has one 30-minute small-group block before the unit assessment.
1. Which of the four responses best meets the Grade 4 standard for describing how a character changes, and why? Explain the specific weakness in each of the other three.

Response B is the only one that meets the standard. It does three things: it names a change over time-from not sharing to giving Mateo another stone; it supports that change with two details from the story, the refusal to let Mateo touch the marble and the gift of the gray stone called lucky; and it draws a reasonable inference about Lena's feelings, that she is starting to think about Mateo. That matches the Grade 4 expectation to describe a character's traits, motivations, or feelings and explain how they change, using details.
Response A gives a judgment, 'mean and then nice,' but no evidence, so a reader cannot tell what Lena did or how the student knows. Response C is a retelling: it lists events in order but does not explain what the events show about Lena, so it does not make an inference. Response D focuses on one moment and misreads the character: the story shows Lena losing the marble and then choosing to comfort Mateo; calling her simply 'sad' misses the change the task asks for. The best response is not the longest or the one with the most events; it is the one that connects selected details to a change.
2. Mr. Alvarez has 30 minutes with a small group of students who wrote responses like A and C. Describe a scaffold that uses the story and moves them toward a response like B. Include at least two question stems and the writing frame you would give.

Start with a two-column chart labeled 'Beginning' and 'Later.' Ask students to find one action in each column, not to retell the whole story. Question stems: 'What does Lena do with the marble at the start?' and 'What does she do after the marble is lost?' Then ask, 'What does that second action tell you about what Lena cares about?' Push for a trait or feeling word and a because. For students who retell, as in Response C, use the stem 'Which one of these events shows the change, and which events are just background?' Have them cross out background events. For students who make bare judgments, as in Response A, use 'What did you see or hear in the story that made you say that?' Give the frame: 'At first, Lena ___. Later, she ___. This shows that she ___, because ___.' Model the frame once with a different character, then have students complete it with a partner and read it aloud. Exit ticket: one sentence with one beginning detail, one later detail, and one inference word.
3. Response D is not just incomplete; it reveals a common inference error. Name the error and explain how you would use a quick turn-and-talk to correct it without telling the student the answer.

The error is substituting a feeling that is present in one scene for the change the whole story traces. Lena may indeed be sad about the marble, but the story's turning point is her choice to give Mateo another stone. A turn-and-talk can correct this without supplying the answer. First ask: 'Find the moment when Lena stops thinking only about the marble. What is she looking at? What does she do next?' Then ask: 'If Lena were only sad, would she give Mateo the gray stone? Why or why not?' Have students underline the sentence 'This one is lucky too' and ask what that sentence shows about Lena's feelings toward Mateo. Close by having the student revise Response D into a two-part sentence: 'Lena is upset about losing the marble, but she ___ because ___.' This corrects the error without erasing the valid observation that she is sad.
