Great question. I include them in the process. If I clean the garage I give them jobs. I was cleaning the workbench and provided a few boxes of random screws, nails, nuts, and bolts - had him sort them by size and shape. This teaches pattern recognition, sorting methods, names of objects, function of objects, and fine motor skills. If I ask for a 10mm socket the 3 year old can identify it including telling me it is used for tightening bolts.
