Geometry; 5/11

We spent some time reviewing the geometric probability concepts that we introduced yesterday with a few more sample problems together.  We then went over the 4 main types of problems missed on the chapter 11 test as a mini group review.  The students then spent the rest of the period working on the chapter 11 review sheet.
