After watching the movie 21, we’ll be looking at how to actually play the game and the probability strategies used by many out there.

# Math B ES1B

## Math B Retests

On Monday at 9.10 in room 4316, there will be a test in Math B for those people to whom I have talked. This test is specifically for people who are in between grades for which I need more basis for setting final grades.

The rest of the students from ES1B are excused from class that day. We will be having class as usual for the rest of the week. Both Math B courses will be watching the movie ”21” these next few weeks and discussing the reality (both math and otherwise) and fiction of the movie.

## Has Math B Really Ended???

Post national tests many students think that a math course has ended when in reality there are lots of loose ends with which to work. For the next week, first years students will have the opportunity to use my Math B class time to work towards Shaekspeare Day. However, I highly recommend for those students who are in danger of failing or are in between grades to continue actively studying. After Shaekspeare day, National tests will be graded in their entirity and grade talks will be done between teacher and student. Any students that are in danger of receiving a fail may have the opportunity to study and take a final test.

## Under the Weather aka Sick

Unfortunately, I am under the weather (aka sick today) and won’t be coming into school. So, please continue your work in each individual classes independantly (aka on your own).

– From Urban Dictionary’s definition of ”under the weather”

During the days when ships were powered by sail, the captains log documented everything that happended during the day. As sickness could spread rapidly on a ship,there were often times where the number of sailers that were ill exceeded the space provided in the log to record their names. During these times, the excess names of the sick were recorded in the next column, which was reserved for the weather conditions of the day. Thus, it was not unusal for an ill sailor to be listed ”under the weather”.
