Tips
To deepen Bentley's learning, have him create a simple spreadsheet that tracks price changes over a month and calculate average, median, and range values. Next, organize a mock trading‑card market day at home where family members negotiate prices, allowing Bentley to apply budgeting and negotiation skills in a real‑world context. Encourage him to interview a local collector or a hobby shop owner (via video call or email) to learn about factors that influence card value, then write a short article summarizing those insights. Finally, challenge Bentley to design his own sports card, set a price based on the research he’s done, and present a persuasive pitch to the family.
