Nadine talked about how the speeds of church bells could be changed by studying its permutations. Using factorials, the number of permutations of bells in "change ringing" could be examined.
Alan researched about measurement and talked about how the human body was used to measure things that are used by human bodies. We still use our bodies to measures things since it is portable wherever we go.
I found the roots of probability interesting. Jenny presented how it originated from games with dices to predict the future while fortune-telling was popular.
Jordan differentiated between traditional logic and algebraic logic. I found this interesting because I never explicitly though about how logic can be categorized into types.

In my presentation, I found that pascal's triangle appears in many countries in different forms and are known by different names. I was reminded about this in Austin's presentation where a single combinatorics question was shown presented in different cultures with slightly different wording.
Ivan talked about how the term "league" was used by the Ojibwa people to represent the measurement of everything. This is interesting because it caused a lot of confusion, but it continued to be used.
Yiru researched about Cavalieri's Principle, stating that if two or more figures have the same cross sectional area at every level and the same height, then the figures have the same volume. I think this would be a great exploration activity for students.
