"...might not be comfortable with what 9 + 6 might mean."

I have no idea what this well-intentioned teacher is talking about.  I am impressed, however, with her ability to turn a simple exercise in addition into near-gibberish.  If we really live in a world where "young learners" are intimidated by two simple numbers and an addition sign, I would like to preach the simplicity and freedom from fear enabled by the use of...flash cards.

[What are flash cards, you ask?  Only the best thing I ever used in my early education.]
