We will talk about some sharing problems, and start to think about how we can make careful arguments to justify our answers.


We will return to the fair share problems that we introduced in week 1, by considering what happens when we have to divide among three people. We will also think about the geometry of plane figures and how many places lines will intersect with different figures.


We will review the homeworks from lesson 3, and introduce Roman numerals as a new topic. Remember to bring your craft sticks to class!
