"Rate of progress between area units" Area of ​​rectangles and squares PPT courseware 2

1. What are the commonly used units of length?

Meters, decimeters, centimeters

2. What is the relationship between two adjacent length units?

1 meter = 10 decimeters, 1 decimeter = 10 centimeters

3. What is the advance rate between each two adjacent length units?

Consolidate the application:

1 square decimeter = ( ) square centimeter

1 square meter = ( ) square decimeter

The rate of progress between each two adjacent area units is ( ).

How to convert between area units:

1. To convert high-level units into low-level units, first think about what the advancement rate is, and then look at how many high-level units there are, and then there will be several advancement rates when converting;

2. When converting low-level units into high-level units, you must first think about the advancement rate, and then look at how many advancement rates there are in the low-level units. The result of the conversion is the number.

I'm a little judge
