I use this activity at the start of the school year and it works in conjunction with the book:
Mistakes That Worked by Charlotte Jones and John Obrien (May 1, 1994)
For a few days leading up to the activity we read about some mistakes that turned into can't live without items. We discuss how mistakes are not a bad thing and that we shouldn't be afraid of making mistakes. After we have read a few, I pass this page out and we complete it.
