What is the quickest way to clear an area of tall grass?

On Minecraft, XBox 360 Edition, I have a 40x40 block area that I plan to build in, except for one small problem; almost all of it is covered in tall grass. What's the quickest way to clear all of this tall grass? NOTE: I would like the actual grass blocks to stay intact


Solution 1:

Pour a bucket of water down. It will knock the tall grass/flowers/etc off the block.

Solution 2:

I suggest you use fire, though be careful not to let it go out of control
