I generally agree that up to around grade 7 there isn't much use for calculators. But from there out if you understand place value and can estimate being consistent and accurate doing long hand calculations is kind of overrated-- I'm always a little shocked that once I tell the grade 9 students they can use calculators they somehow keep making arithmetic errors... (HOW) not this student, though!

She might even like math now. Imagine that.
