1. First of all, we can compare firecrackers to a cylinder with a circle at the bottom. Two lines extend upward along the circle, and the two lines are sealed with an arc, so you can draw a firecracker.

2. After painting a firecracker, we need to draw more cylindrical firecrackers. Be sure to pay attention to the context when arranging, and don't draw the invisible parts.

3. After drawing a row, let's draw a row of firecrackers and draw a spark decoration below. It should be noted that the pattern on firecrackers is very important, so that a complete string of firecrackers can be completed.

The next step is to color the firecrackers that have been painted. The center of firecrackers is red. Note that firecrackers that have exploded also need to be filled with color.

5. Finally, paint both ends of firecrackers yellow, and the sparks that explode need to be painted yellow. Orange can be used to express the color depth relationship between the inner ring and the outer ring, so that simple colored stick figure firecrackers are completed.

Learning painting has many advantages, such as improving creative thinking, cultivating keen observation, flexible hands-on ability and initial aesthetic ability. This process cultivates students' sensitivity, imagination and creativity to beauty through various interesting creative activities such as painting, design and craft making, and brings them to a beautiful reality and a beautiful spiritual world.
