We started by looking at math problems, especially with inequalities. They are similar to equations with an equals sign in many ways.
Part of the time, you want to look at what you have and the expression that is mentioned later and see what you could do to get to that later expression. Here there was a division in one problem and a multiplication (by whole numbers) that did the trick.
Also looked at a passage by Thomas Jefferson. Usually could eliminate a few choices quickly and then choose between two. Sometimes, they are a bit subjective. For a few, a single word in the question was important like, “initial.”
