Level 1: COMMON CORE Note: Since training shops differ from place to place, the following is only a guideline for shop equipment.
The tool list is based on the following assumptions:
16 trainees per class Trainees will do shop activities in two person teams (i.e. odd numbered teams promote the “odd
person out”, and leave one person doing little learning) Projects can be staggered between groups, thus reducing the demand for high numbers of equipment Tools are listed in groups of 2, 4 or 8 to accommodate 8 - two person teams The shop has adequate tool shortage cabinets
