1. Understand the concept of scale: scale is used to express the proportional relationship between the distance on the map and the actual distance. It is usually expressed as 1:x or x: 1, where 1 represents the distance on the map and x represents the actual distance.

2. Learn to calculate the scale: When the distance on the map and the actual distance are known, the scale can be calculated by the following formula:

Actual distance = distance on map × scale.

Map distance = actual distance ÷ scale

3. Pay attention to unit conversion: when using scale calculation, you need to pay attention to the unity of units. For example, if the distance on the map is in centimeters and the actual distance is in kilometers, you need to convert them into the same units before calculation.

4. Learn to analyze topics: When solving the scale problem, learn to extract key information from topics, such as the distance on the map and the actual distance. In addition, we should also pay attention to the implicit conditions in the title, such as whether the scale of the map is consistent.

5. Master problem-solving methods: according to the requirements of the topic, use the knowledge you have learned to solve problems. For example, if the topic requires calculating the actual distance between two places, you can first calculate the distance of a place on the map according to the scale, and then multiply the scale to get the actual distance; If the topic requires judging whether two places are in the same direction, it can be judged according to the size of the scale.

6. Do more exercises: through a large number of exercises, be familiar with the calculation method of scale and problem-solving skills, and improve the speed and accuracy of problem solving.
