I found this lesson in the University section and changed it a bit for my advanced high school students (grade 1s). Thanks Brian, for posting the original there.
It's a two week lesson, I divided the colour idioms in half (20 week 1, then 18 week 2) and will have students prepare a dialogue using 2 random idioms, a random place and a random situation (they'll draw these from boxes). They'll prepare their dialogues with their partner week 1, and present week 2. After they present I'll go over the last 18 idioms. I tried to choose the 20 I thought they'd enjoy most/be more likely to use in their own lives for the first week.
We'll be starting this lesson next week.
