HAHA! We just did that this week with my 9yo. She had a book report to do, picked the book herself, wrote it and turned it in without us looking at it first. So we came up with this:

Answer the following questions:
Who?
What?
When?
Where?
Why?
How?

Then put it in an order that makes sense when its read outloud.

I might just try yours next time though, leaves little wiggle room for those that are prone to daydream.

The impossible is just something that hasn't happened yet.
