Aligned lesson plans
- Using percent of change to measure growth in North Carolina
- Students will work in small groups to use the internet to gather data on the population growth for each of the 100 counties in North Carolina from 1992 to 1995. From these data, students will find the percent of increase/decrease for the counties they have been assigned. As a follow-up, the students will enter their data into a computer spreadsheet and from that spreadsheet, produce graphs of the information.
