STEP 1: Make the Niyyah (Intention) for Tayyammum:
STEP 2: Strike both hands on the earth, sand or dust or any object having dust on it. Then, dust the hands clean or blow the extra dust off the hands and wipe the entire face (as done in Wudu) without leaving out any part of the face.
STEP 3: Strike both hands again on the ground, dust clean and wipe the right arm up to the elbow with the left hand and left arm with the right hand. Make Khilal of the fingers. If one is wearing a ring or bangle, it is necessary to remove it or shift it. If one has a beard, it is Sunnah to also make Khilal of the beard (run fingers through the beard).
