Subject: Volume and unit of volume Course Type: Inquiry Class Time:No.: 20 1 1050306.
Learning objective: 1. Understand the meaning of volume, master the commonly used unit of volume and their forward speed.
2, master the relationship and difference between volume and volume, know the relationship between unit of volume and unit of volume.
3. Feel the practical significance of 1ml, apply what you have learned and solve simple problems in life.
Difficult presupposition: Establish the concepts of volume and unit of volume, and convert them into unit of volume.
Learning process:
Recall it and tell your partner.
What have we learned about unit of volume? What is the rate of progress between them?
Clear objectives: Please study the learning objectives.
First, autonomous learning.
Teach yourself the textbook 50,51page, and then answer the following questions.
1, which targets are liters and milliliters?
2. What is volume? Can you give me an example?
3. What is unit of volume? What is the relationship between the unit of volume and the unit of volume?
4. How to calculate the volume of cuboid and cube containers?
First, give it a try:
The fuel tank on the car has an internal length of 5 mm,
4dm in width and 2dm in height. This mailbox can hold
How many liters of gasoline?
Second, students, you have solved the volume of cuboid and cube containers. So how to solve the volume of irregular objects? Self-study Example 6, and you will gain something new!
Try it yourself.

First, basic courses
1、4L=( )ml 4800 ml=( ) L
2.4 l = () ml 500 ml = () l
2. A cuboid freezer, measured from the inside, is 87.5 cm long, 50 cm wide and 56 cm deep. How many liters does it have?
Second, expand
Finish page 52 of the textbook and do the second question.
Method tip:
Memorize 1, 2, 3, 4!
Think carefully, summarize and write it down.
To calculate the volume of the container, all data should be measured from the inside of the container.
The volume of irregular objects can not be directly calculated, but can be measured by other regular objects. For example; water
