Understanding rice and measuring with rice PPT, Part 2: Scenario introduction

This is a student ruler, 20 centimeters long. Who wants to use it to measure the length of the blackboard?

I come! I come!

Try this meter stick.

This measurement is too troublesome.

It only took two measurements and the blackboard was two rulers long.

PPT on understanding rice and measuring with rice, part three: exploring new knowledge

Take a meter stick and measure it on your body. Is it 1 meter?

From the ground to my neck, the length is about 1 meter.

The length of my arms open is about 1 meter.

Compare, what do you think is the relationship between meters and centimeters?

1 meter is much longer than 1 centimeter.

There are many centimeters in 1 meter.

Let’s count together: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. This is 10 centimeters.

When comparing the heights of the three children, Xiaojun is the tallest and Xiaohong is the shortest. Xiaogang's height may be ( ) centimeters.

4. 1 meter = ( ) centimeter

100 cm = ( ) meter

6 meters = ( ) centimeters

500 cm = ( ) meter

4 meters = ( ) centimeters

300 cm = ( ) meter
