Welcome to Bridges Canada!
A 2- to 24-item sorting activity with anodized aluminum pieces, requiring attention to three relevant dimensions: color (silver and gold), shape (circle, square, rectangle and hexagon) and thickness (thin, medium and thick). Many variations are possible: sort by shape only, shape and color, color only, color and thickness and many more.
Includes 120 aluminum pieces and all bins. Also includes 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.
