Second grade 'estimated' multiplication

So I'm checking over my daughter's homework tonight. It's a math assignment called 'estimated' multiplication. It goes something like this:

62 X 6 = ?

You round the 62 to the nearest ten (60), then multiply it by the 6. So the "correct" answer is 360.

W.....T.....F??????

She knows how to multiply 62 X 6, but is being forced to use this..."fuzzy math"... multiplication. Can any educators please explain to me the logic behind this??? Why not just teach multiplication the proper way?
