I have discovered that teaching programming goes much better with my fifth grade students if I take the time to teach them about all the symbols I think of as "normal" that are totally new to them.
"These are square brackets, you'll find them over the 'enter' key we use them for lists. In programming we have three kinds of brackets..."
This reduced confusion so much. And I feel a little silly for not realizing that OF COURSE they don't know what they characters are or how to type them.
