The first lesson of the Coordinates and Design unit is based around the Cartesian Plane, something the students were introduced to last year. I put the reading assignment and the example on the board for the grade 7s to work on. I should have explained to them that I only wanted them to read the textbook and NOT complete the examples in the textbook. This caused me a little bit of re-planning as none of the students had completed the example on the board, but that just allowed us to go through it as a class. The students were very knowledgeable about the material, and after a few examples grasped the concept very quickly.Make sure that you have graph paper available for the students to work with, also it is important to review what longitude and latitude is with the class if you are using question 18.
