So I came up with W.W.H.Ns.
WWHN (Who, what, how, now) I give them a short list of important people or events and they write a WWHN about each one.
The way it works is that they have to identify WHO person(s), or group of interest. Then they have to write out WHAT is was or WHAT is so important about them. Next they have to say HOW they affected history. Lastly, they have to think about how they/it affects us NOW. When I learned this, I was told it can be used in all subjects.
