CareerStart lessons: Grade seven

LEARN NC was a program of the University of North Carolina at Chapel Hill School of Education from 1997 – 2013. It provided lesson plans, professional development, and innovative web resources to support teachers, build community, and improve K-12 education in North Carolina. Learn NC is no longer supported by the School of Education – this is a historical archive of their website.

Activities

  1. Ask the students if any of them have attended a fair such as the Dixie Classic Fair or the North Carolina State Fair. Tell students they will take on the role of planners for the Dixie Classic Fair. Students will be in charge of ordering food items for the fair, and must order enough to last the entire 10-day fair week. (5 minutes)
  2. Place students in groups of two or three, and hand out the fair concession worksheet. Instruct students to complete the worksheet. (40 minutes)
  3. Project the overhead copy of the worksheet and have each group write answers to share with the class. (5 minutes)
  4. Discuss with students what other careers might need to calculate percents. (Examples may include loan officers, retail workers, small business owners, etc.) (5 minutes)
