Today I read the book 26 LETTERS AND 99 CENTS. There are many items in this book which can be sorted, including numbers, letters and coins. The mathematicians were put into groups and asked to work with their friends to sort these items into three groups. After this initial sorting, they were asked to sort again, into three different groups. What interesting ideas they had! Take a peak to see them in action!
