Assess three short picture-book stories for Pre-K–Grade 2 and determine which most effectively teaches kindness. For each book, identify 2–3 specific plot events and character actions that support or undermine the kindness lesson; compare the books using clear evaluation criteria (e.g., clarity of moral, modeling of kind behaviors, consequences/resolution, age-appropriateness); then select the single most effective story and justify your choice with evidence-based reasoning and a suggested classroom learning objective.
