A simple way to teach it

Before the lesson

Use pages 1–2 and keep the teacher key on page 3 for feedback. Introduce unaware and unprepared, checking meaning and pronunciation before the gap fill.

  1. Distinguish being unaware of a change from being unprepared for a task; use the remaining clues to identify the other adjectives.
  2. Complete the eight sentences using each vocabulary word once. Compare choices with a partner and explain the context clues before checking the key.
  3. Discuss unreasonable expectations, unprofessional behaviour and unproductive meetings. Use the five printed questions for pair discussion and short notes; responses are individual, not fixed-key answers.

Support and extension

Support with a workplace scenario chart; extend by proposing changes that would make a meeting more productive.

Suggested approach. Adjust the pace and number of questions to suit your class.
