I start out by demonstrating the general speech pattern with the JTE. For example:
I might write the question and answers up on the black board to make sure the students understand the pattern. Then I pass out the papers and assign the students one of the following times:
You could assign each student a number and have them write one based on their number, or allow them to choose one time period. I tell the students that they need to ask for their classmates' advice about what they should do. It's good to review what each of these mean - what does "something to wear" mean? How about "something to read?"
Once the students understand the idea of the activity, I have them stand up and ask the questions to their classmates. Under the advice box they write what their classmate said (like "chestnuts" in the example above).
I found this particular grammar point kind of challenging to practice, but this was the clearest activity I've been able to come up with.
