There’s a site I’ve recommended for years when new homeschoolers want a list of topics that they “ought” to cover. I just skimmed over the listing for preschoolers again as I was comparing their lists to what my three year-old already knows. I was rather surprised to find it now contains a section called “technology.” When I first found this list, long before my now 15-year-old was old enough to officially be homeschooled, there was no such section. I don’t believe preschoolers need to know how to do any of the things listed. I think technology can wait. But then again, if the preschooler is the youngest in the house, and you need to keep him quiet sometimes while lessons are happening with his siblings, the preschooler will definitely be more familiar with technology than his older siblings were at even in their elementary grade years. Sometimes practicality trumps theories.
