🎤 Rounding Revelations Budget Presentation

Teams present their Family Grocery Budget Report slideshow to classmates (and record for the digital exhibition). Each presentation must clearly state the research question, describe the rounding method used (number line or digit analysis), show exact vs. rounded totals with a bar graph, explain patterns discovered, and state whether the family stayed within budget. Students must explicitly name at least one limitation (e.g., pretend prices, limited items) and one new question their data raised. After each presentation, audience members ask 1–2 questions about methodology or conclusions.
