Today’s warm up was a look back at some of last week’s ideas but with an open question spin on it. 
For warm ups students go to the vertical whiteboards or blackboard and work together. They are only allowed one marker. After a few minutes of work I yell out “switch marker”. They are supposed to pass the marker to their partner….and keep working together. Passing the marker keeps from one person writing all of the work and promotes discussion.
Most students completed a solution like the one below. They picked the hours worked…but started with $1000. Some groups chose their own hourly rate and built up the bi-weekly pay. A few groups had to adjust their hourly rates to keep the bi-weekly pay under $1000.
We picked up where we left off on Friday and finished researching flights to San Francisco in about a half hour.
For the remainder of class we talked about time zones. I displayed the World Clock from my iPad.
I then presented them with some screen shots from my phone with some missing values. They had to determine the missing values on their desks.
We ran out of time here…..so tomorrow we’ll work on the rest of the time zone/24 hour clock exercises and then start researching train and bus routes to San Francisco.
