Adapting the lesson

ForWhat to change
A large class (40 or more)Keep the pairwork in "Freer practice" in fixed pairs rather than a mingle, and take feedback from four or five pairs instead of the whole room. Monitor one half of the room during "Controlled practice" and the other half during "Freer practice".
A class with no photocopierPut the exercises from Handout 3: Practice on the board for learners to copy into their notebooks, and read any text aloud twice instead of printing it. The board plan above is this lesson's minimum - with that on the board, it runs on no paper at all.
An online classSend Handouts 1 to 4 in the chat before the lesson and put the board plan on a shared slide. Use breakout rooms for the pairwork in "Freer practice" and visit each room once. Have learners type the controlled answers in the chat, so you see every answer at once instead of nominating.
A different age groupWith teenagers at this level, cut the academic framing and keep the examples in their own world; the forms do not change. With adults in a work context, swap the lesson's texts for ones from their own field and keep the analysis as it stands.

Checking learning

The final report uses at least eight complex prepositions accurately. No due to / in spite of + clause errors. 7 out of 8 or better on Handout 3, Exercise A.

Handout 2: Model Report

Report on the School Canteen

Purpose: This report has been prepared on behalf of the student council with regard to the school canteen. It is based on a survey of 300 students conducted in accordance with school guidelines.

Findings: In spite of recent improvements, only 35% of students are satisfied with the quality of food. Owing to rising costs, 72% feel that prices are too high. In addition to price, healthy eating is a major concern: 81% want more healthy options. Queues are also a problem on account of the short lunch break.

Recommendations: In the light of these findings, we recommend that the menu be placed under review. Regardless of the cost, fresh fruit should be available daily. With a view to reducing queues, a pre-order system could be introduced by means of a simple mobile app. The success of the canteen is at stake, and we would be grateful for the principal's support.

Find and categorise the complex prepositions.
