Practical exercise
Author purpose tags on five varied texts
You will pick five very different texts from one week of your normal reading and tag each one with its dominant and secondary purpose, with one line of evidence for each tag. The aim is not to be right; the aim is to make the act of naming purpose automatic.

Author purpose tags on five varied texts
Stretch
Repeat with five texts on the same topic, like five different writers on the 1965 war. The grid will reveal each writer's purpose far more clearly than any single piece does.
Goes into your portfolio
One sheet titled purpose-grid-NN with five rows of dominant purpose, evidence quote, secondary purpose, evidence quote, trust score, plus a three sentence reflection at the bottom.
