Manufacturing Quality Control Challenge: Perfecting Your Craft

This resource, published by Georgia Tech Research Institute, features a math data visualization activity designed for seventh graders. In this activity, students utilize "inference and measures of center and variability to investigate the error rate of random samples of hex nuts to determine if a manufacturing production line has exceeded the allowable error and needs to be repaired." The activity is divided into four sections that take up five class periods. The resource includes the following:

• A 10-page teacher's prep guide for the activity
• An 18-page curriculum workbook with an annotated teacher's version
• Materials list
• Supply checklist
• A 12-page student worksheet packet
• Three videos providing context for quality control and production line manufacturing
