Well, first you craft yourself a hoe (any material, stone recommended) and start plowing around on the grass (quickly tapping the screen) and you will get seeds sometimes. Then plow more ground (not randomly, maybe make some nice farming area) and plant the seeds there (quickly tapping the screen with seeds in hand) and wait. After a little while, they will be tall and more yellow. After they have slight brownish tops on them, they should be done. Break them and enjoy your wheat (replant the seeds). NOTES: if you plant near water, they grow faster. Also, dont walk on it while its growing, it can break it. Also, if you don't feel like waiting, you can use some bones to make bonemeal which grows it instantly.
