The move these teach is choosing what the letter stands for. Once a child writes down that the younger age is the unknown, the older age is an expression in it — three times as old, or seven years more — and the sentence in the story becomes an equation almost by itself. Naming the right unknown is most of the work.
The ones that reach into the future are where it gets interesting, because both ages grow by the same amount. In four years both people are four years older, and holding that steady is the reasoning the problem is really testing — a mistake there is a mistake about time, not about algebra.
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
