Here is the White House press release of President Obama's remarks to the schoolchildren of America.
When I was in elementary and high school, the presidents were Dwight D. Eisenhower, John F. Kennedy, and Lyndon B. Johnson.
Had they given such a talk, Eisenhower would have put us to sleep and Kennedy would have been classy. As for LBJ, one comedian accurately noted that his speeches often sounded like greeting cards:
"Your president is here today
To wish you luck in every way."
