Chicago grid system and starting new unit on probability

This week in 6th grade math, the students are learning about the Chicago street grid system.  On Monday, the class looked at maps and and wrote down all the north and west streets for the entire city by 400 blocks.  It was great to see them all over the floor looking at the maps of Chicago and figuring out how the system works.  We will continue to work with the grid system on Wednesday and I will ask them to find their exact street coordinates of where they live, so that other students can find their house on a coordinate plane.  Then on Thursday, we will finally start our new unit on Probability using the experimental textbook.
