Video Summary

In this Super Bowl Sunday webinar titled "Make a Table, Make a List," the instructor guides students through various math problems, emphasizing organizational strategies like lists, tables, and casework to solve complex problems systematically and avoid missing any possibilities. Early problems involve summing pairs of numbers and exploring distinct two-digit numbers formed from different odd digits, introducing the usefulness of structured lists.<br /><br />The instructor then tackles problems involving divisibility, group division, and triangle formation conditions, illustrating strategies such as factoring and applying the triangle inequality. For example, dividing 96 participants into equal groups with group sizes between 5 and 20 was solved by examining divisors of 96 within that range. The triangle problem involved selecting segment lengths to satisfy triangle inequalities.<br /><br />Three-dimensional arrangement problems are also discussed, including constructing a 2x2x2 cube from black and white unit cubes, accounting for rotations to avoid counting duplicates. The webinar also covers combinatorial coloring problems where adjacent selections are restricted.<br /><br />A particularly challenging problem involves finding five-digit numbers with digits 1-5 satisfying divisibility rules for 2, 3, 4, and 5 simultaneously. Through analysis using divisibility rules, it was concluded such a number does not exist.<br /><br />The session stresses the value of organizing data to enhance clarity and accuracy, encourages students to develop their own tables or lists, and recommends practice to handle higher-point, time-consuming problems effectively. Attendees are encouraged to review recorded webinars and engage in problem-solving challenges at home.<br /><br />Overall, the webinar provides practical strategies for tackling multi-attribute mathematical problems through organized lists and tables, reinforcing fundamental concepts like divisibility, factors, and combinatorics in a supportive, interactive environment.
