First, get to know your pencil: H is hard and light, B is soft and dark. Students learn to sharpen a pencil by hand, hold it the right way, and loosen up the wrist with a “rubber pencil” trick. Then they shade a “Rainbow Python” — pencil tones that go from light to dark. 先認識鉛筆:H 比較硬、顏色淡;B 比較軟、顏色深。學生學習自己削鉛筆、正確握筆,再用「鉛筆變軟了」的視覺魔術放鬆手腕,然後畫出由淺到深的「彩虹大蟒蛇」。
