Why does Addie need poster board in Tumble?

In "Tumble," Addie needs poster board for a Mythology Assignment/Project. This requirement reflects the thematic focus of the story, where elements of mythology play a significant role in the character's development and the plot's progression. The use of poster board signifies a creative and educational approach to learning about myths, allowing Addie to explore her interests and express her understanding visually. The assignment likely engages her with the subject matter in a practical way, enhancing her comprehension through artistic interpretation.

The other options, while plausible in a school setting, do not specifically align with the context of Addie's assignment in the story. For instance, a Science Fair project could require similar materials but does not connect to the thematic elements within "Tumble." Similarly, creating a birthday card or an art class project might require poster board but wouldn't provide the same narrative significance related to mythology. Overall, the need for the poster board highlights Addie's academic pursuits and her engagement with mythology, which is central to her character's journey.
