Session+4

April 15, 2011 We began the lesson by having the students work individually on the shading problem from the pre-test that we modeled on Monday. We then went over the solution as a class on the document camera. We then handed out sheets that gave the concept and purpose of scale, which we explained to the class again, but in more depth. We used the example map on this sheet in our explanation, displaying it on the document camera. We had students find the distance between 2 cities on the map, using this scale. Next, we modeled to the students how to solve the other scale problem (the farmer problem) from the pre-test on the document camera. Finally, we broke the class into their groups and gave them some time to start brainstorming ideas for their projects.
