Two checks while you read. First, unfair treatment is only discrimination in the legal sense when it is linked to one of these grounds. Second, plenty of things feel unfair and still fall outside the nine, such as having less money or holding a political view. The next lesson will practise applying the list. Today the job is to know the nine cold.

When the class is ready, the nine on the board will be covered. On paper, write all nine grounds from memory in four silent minutes. No phones, no neighbour checks. Then uncover the board and tick what you got. Fix any you missed so your final list is complete. If you have fewer than seven right after the self-check, use the word bank your teacher gives you for a second pass so you leave with a full list.
