I've decided to be an Egyptian Fraction for Halloween. I teach a class at ISU called, Dimensions of Numerical Analysis I. In this class, we take an indepth perspective on the teaching and learning of rational number. As part of this class, students learn how to conceptually, rather than procedurally, explain and justify rational numbers, as well as operations about them. I decided that if I was going to wear a mathy Halloween costume to class, it definitely needed a rational number flair. So... I decided to be an Egyptian Fraction. I can't wait for my class to laugh at this one. :) What is an Egyptian Fraction?
I love the Wolfram MathWorld page about Egyptian fractions! You should check it out! http://mathworld.wolfram.com/EgyptianFraction.html For elementary students.I found this online game for elementary students (the website recommends 5th graders), that incorporates the concept of sums of unit fractions with circle models to represent fractions. I think it is a fun way to incorporate a little mathematics history in the classroom. Enjoy! http://www.mathcats.com/explore/oldegyptianfractions.html
