Counting can be especially challenging when there are symmetries involved. How many ways are there of tiling a 3x3 square with black and white tiles\, if two tilings that differ by a rotation are considered equal? How many ways of coloring the 6 sides of a cube with 3 colors\, up to a rotation of the cube? We will explore Polya's counting method\, which can be used to answer these and similar questions.\nTo ensure the safety and enjoyment of all attending the event:\n- If bringing 5 or more students\, it is expected that a parent/teacher/guardian remains with their students for supervision.\n- If bringing 4 or fewer students\, we prefer if a parent/teacher/guardian remains at the event\; however\, if this is not possible\, please leave an emergency contact number in the RSVP to the event.\nPizza and pop will be served. To give us accurate numbers for food orders\, we ask that you RSVP to mathcircles@dal.ca (mailto:mathcircles@dal.ca?subject=RSVP%20for%20monthly%20Math%20Circles%20event LOCATION:Learning Center #119\, Chase Building URL:https://www.dal.ca/faculty/science/math-stats/news-events/events/2019/01/16/math_circles_event.html UID:https://www.dal.ca/faculty/science/math-stats/news-events/events/2019/01/16/math_circles_event/_jcr_content/contentPar/dcalfacultyevent.html END:VEVENT END:VCALENDAR
