Tin học 3- Cách đặt tay trên bàn phím và cách gõ bàn phím bằng 10 ngón tay

Welcome to Vui learning with Mrs. Thuy. Today I will show you how to put your hand on the purple board and how to fold the purple board with 10 fingers. To fold the purple board with 10 fingers and put it in the right position on the purple board, first we need to sit in the right position. Please observe the little friend in the picture. This is the correct working position with the computer. We need to sit in the right position and feel comfortable so that we can work effectively. When folding the purple board, you don't need to look at the purple board, but you can still fold it quickly and accurately. Then you will save effort, working time with the computer, avoid harm to your health, such as eye fatigue, neck pain, finger pain, and arm pain. Now I will show you how to put your hand on the purple board before folding the purple board. Our hand will be placed on the base of the purple board. Please observe the picture. On the base of the purple board, there are 2 purple boards. There is a G and a G. This is the pin to put our hand on the purple board. The left hand will be placed on the F. The right hand will be placed on the G. The rest of the fingers will be placed on the sides. Our hand is a little bent. You place it gently, do not press the pin down. Now I will show you in detail with the left hand. The thumb is placed on the F. The middle finger is placed on the G. The thumb is placed on the S. The thumb is placed on the A. The thumb is placed on the X. Similarly, with the right hand, the thumb is placed on the G. The middle finger is placed on the K. The thumb is placed on the N. The thumb is placed on the X. Two fingers are placed on the side. Now I will show you how to fold the purple board with 10 fingers. Please observe the picture. On the purple board, the purple boards are designed in a diagonal line. When folding, the purple boards follow the diagonal line as follows. For example, with the thumb of the left hand, we will fold it like this. The fingers are always placed on the side of the base. When folding, our hand will bend up to fold that side. After folding, we will take the fingers back to the original position. With the thumb, we will fold it like this. You bend your fingers up to fold. Similarly, with the thumb of the right hand, with the thumb of the left hand, we will fold two diagonal lines. And the next diagonal line, with the thumb, we will fold it like this. The thumb of the right hand will also fold two diagonal lines. Similarly, with the remaining fingers, we will fold. Please note that to practice folding the purple board with 10 fingers, we need to practice holding, pressing, then we can fold. I wish you success.
