A simple way to teach it
Before the lesson
Use pages 1–2 and keep the teacher key on page 3 for feedback. Introduce inaccurate and incomplete, checking meaning and pronunciation before the gap fill.
- Contrast inaccurate information with an incomplete form; clarify insecure as not confident or not safe.
- Complete the eight sentences using each vocabulary word once. Compare choices with a partner and explain the context clues before checking the key.
- Compare informal situations, inexpensive activities and inconsiderate public behaviour. Use the five printed questions for pair discussion and short notes; responses are individual, not fixed-key answers.
Support and extension
Support with short situational examples; extend by checking how the meaning of insecure changes with its context.
Suggested approach. Adjust the pace and number of questions to suit your class.
