Final answer:
Jack Will first saw August at Beecher Prep during a special tour arranged by the school principal before the start of the school year.
Step-by-step explanation:
In the book Wonder, Jack Will saw August for the very first time at Beecher Prep before school started. They met during a special tour arranged by the school principal for August and a few other students. However, this content provided does not match with the book Wonder by R.J. Palacio, where this specific event takes place. The provided passages do not relate to the characters or events of Wonder, and therefore do not assist in answering the question posed.
