Jodi Chandler, 1st grade, Deer Creek Elementary. The eliminated candidate's first place votes are removed, with the second choice of the voters for the eliminated candidate "counting" in the next round. Although counting is one of the best ways to help children develop number sense and other important mathematical ideas, we do not do enough of it in elementary schools. Why not simply count all the 2nd votes from all candidates? I would use this kit everyday when we do math. I love all the different choices. Mathematics.of.choice.How.to.count.without.counting.pdf. Mathematics of choice: How to count without counting. I definitely plan on starting a counting collection in my class. Word problems, skip counting, graphing. Counts the number of permutations of n objects, that is, the number of different ways to take n distinct objects and arrange them in an ordered list. Well, there are n objects we could choose to put first; once we've made that choice, there are n-1 remaining objects we could choose to go second; then n-2 choices for the third object, and so on, for a total of n (n-1) (n-2) \dots 1 = n choices. Why should I Why do the students record their counts?
