It’s all about engagement. I’ve heard things like a child’s attention span, in minutes, is equal to their age in years. That’s so not true. If children are engaged in something, they’ll spend hours on it. We have a 6-year-old grandchild who will spend hours working on Legos or Tinkertoys because she’s got something in her mind that she wants to build, and she’ll do it. If children aren’t paying attention, it’s not because of a decreased attention span—it’s because they aren’t given tasks that honor their dominant ways of learning.
