1. Draw a text box on white paper.

2. Write "Multiple digits in grade times one digit" in the text box.

3. Draw two-level titles on both sides, and then add the related content of "three-level digits multiplied by one digit" to the second-level title.

4. Add several smaller branches to the branch to increase relevant content. The mind map of "multiple digits multiplied by one digit in grade three" is done.

Multiplying a digit by a digit refers to the process of multiplying a digit by a digit. For multiple digits multiplied by one digit, we can multiply it bit by bit from the lowest digit, operate according to the rule of carry, and finally get the result.

To multiply multiple numbers by one number:

1. Multiply a number with the lowest number among multiple numbers to get a partial result of one digit.

2. Multiply a number with ten numbers of multiple numbers to get a partial result of ten numbers. If there is a carry, you need to add a value with a carry.

3. Multiply a digit by the hundredth and thousands of digits in turn to get some results of the corresponding digits, and carry should also be considered.

4. Add all the partial results to get the final result.

Application of Multiplying Multiple Numbers by One Number

1, shopping calculation: When you shop in the store, you need to calculate the total price. If the price of a commodity is multi-digit and the quantity you buy is single-digit, then you need to multiply the multi-digit by one-digit to calculate the total price.

2. Relationship between speed, time and distance: In physics, the relationship between speed, time and distance is often multiplied by a number. For example, speed (multiple digits) multiplied by time (single digits) can get the distance.

3. Calculation of area and volume: In mathematics, when calculating the area or volume of a shape, it is often necessary to multiply a number by a number. For example, calculate the area of a rectangle (length times width) or the volume of a cuboid (length times width times height).

4. Scientific calculation: In scientific experiments, it is often necessary to multiply multiple numbers by one number to calculate various data. Such as calculating the amount of substances in chemical reactions or calculating various parameters in physical experiments.

5. Mathematical problems in daily life: such as calculating family budget, planning expenditure, etc. , you need to multiply multiple numbers by one number.
