Grandpa Vanderhof is the moral center of You Can't Take It With You, a man who left his business career decades ago because he stopped enjoying it. His outlook shapes how every member of the household lives, and it clashes directly with the values of the visiting Kirbys. For students, he is an engaging subject because his ideas are easy to state and surprisingly difficult to evaluate.

A well-designed prompt asks students to move beyond admiration. Instead of describing why Grandpa is wise, they might evaluate whether his philosophy is practical, who benefits from it, and who bears its costs. The fact that he has avoided income tax, for instance, raises questions about responsibility that thoughtful students will want to address.

This is a good opportunity to practice argument writing in a literary context. Students must take a position, anticipate objections, and support their claims with textual evidence. Graders can look for the same skills they would expect in any argumentative essay, applied to the particulars of the play.

Prompts That Invite Real Debate

The best prompts allow reasonable people to disagree. Asking whether Grandpa's way of life is admirable or irresponsible, for example, produces essays on both sides, and both can be strong if well supported. Teachers should be explicit that the grade depends on the quality of the argument rather than on agreement with the teacher's own view.

• Evaluate whether Grandpa's philosophy would work outside his own household
• Argue whether the play treats his refusal to pay taxes as harmless or problematic
• Analyze how Grandpa influences the choices of Alice, Tony, and Anthony Kirby
• Consider how his outlook is shaped by what he gave up
• Discuss whether the ending proves him right or simply shows one person changing

Evaluating Counterarguments

A mature essay does not ignore the strongest objection to its own position. A student defending Grandpa should acknowledge that his lifestyle depends on other people carrying burdens he declines to share, while a student criticizing him should acknowledge the genuine happiness he creates. Include a rubric row for counterargument so students understand that engaging an opposing view is an expectation.

When feedback is needed, point to the specific place where a counterargument could be introduced. A comment such as consider how a reader who admires Grandpa might respond to this point gives students a concrete next step. This is more effective than simply writing add a counterargument in the margin.

Staying Grounded in the Text

Because the topic invites broad reflection on life and work, essays can drift into general philosophy. Remind students that every claim must be tied to a moment in the play. A paragraph about the meaning of success that never mentions a scene is not a literary analysis, however thoughtful it may be.

A simple check is to count how many paragraphs include specific references to characters or events. If one or two paragraphs lack them, the feedback should ask the writer to find supporting moments. This keeps the essay anchored in the play and sharpens the argument.

Making Feedback Manageable

Argumentative essays can take longer to grade because the reasoning must be evaluated carefully. Rubric-aligned AI feedback can help by flagging missing counterarguments, thin evidence, or unsupported claims. Teachers then confirm and refine the comments rather than composing each from scratch.

This approach preserves the teacher's role as the final judge while recognizing that routine observations do not need to be written dozens of times. It also keeps the tone consistent across essays, which is helpful in a unit where students hold strong and sometimes opposing views. Fair, predictable feedback encourages them to keep thinking and revising.
