Welcome to Bridges Canada!
This moderate level, sorting task introduces inspection and quality control of several relevant cues including surface condition (e.g. hole/no hole). Includes metal plates of two types—aluminum and brass, in two shapes—square and hexagon, with the aluminum pieces with and without holes.
Includes 120 metal plates of 6 types and all bins. Also included are step-by-step instructions and data sheets. The instructions detail many variations for this task. Sorting tasks are not timed so there are no norms.
