Teaching Diary - Hand shape

Palm is like a home to support your fingers. If it collapses, the flexibility of fingers will be lowered. In order to let students know how to support the palm and fingers, I design this activity and let them feel more about their hand shape. 

I put two erasers on her hands and ask her not to let it fall. She resists to correct her bad habit at the beginning. But after several attempts, she feels tired to pick the eraser up. She finally pays attention to her hand shape and tries hard to hold the correct posture!
