Students will launch the investigation by using maps, landmark information, and sample travel data to propose and question an initial vacation plan for a family of four.

Students will narrow their investigation to one U.S. landmark, develop a focused planning question and tentative hypothesis, gather and evaluate travel evidence, and revise a systematic data-collection plan through peer critique.

Students will apply standard multiplication and division algorithms to vacation data, interpret remainders in context, compare revised costs with earlier estimates, and use two rounds of feedback to strengthen their travel math portfolios and team itineraries.

Students will present, defend, and submit their evidence-based vacation plans during a culminating Family Vacation Expo.
