Description

"Interesting Measurement" Cuboid PPT Courseware

teaching objectives

1. Knowledge and skills: Combined with specific activity situations, experience the experimental process of measuring stones, and explore methods for measuring the volume of irregular objects.

2. Process and methods: In the process of practice and exploration, try to use a variety of methods to solve practical problems.

3. Emotions, attitudes and values: Develop everyone’s spatial concept through observation and operation.

Transformation is a very important mathematical idea and method. In fact, every day we transform new problems into old knowledge we have mastered and solve one problem after another.

For example: we use the "common fraction" method to convert fractions with different denominators into fractions with the same denominator to compare the sizes of fractions with different denominators and calculate the addition and subtraction of fractions with different denominators;

Convert the parallelogram into a rectangle and calculate its area.

Operational requirements:

1. Pay attention to safety, do not spill water on the table, and tidy up the equipment after the operation is completed.

2. Have a clear division of labor, work together, observe carefully, obey the team leader’s arrangements and keep records together with the team leader.

3. Think carefully about how to calculate the volume of rocks.

4. Compare which group has the best discipline and the fastest completion.

give it a try

1. A rectangular container has a bottom length of 2 decimeters and a width of 1.5 decimeters. When a potato is placed, the water level rises by 0.2 decimeters. What is the volume of the potato?

2. A rectangular container with a square bottom and a side length of 5 cm contains some water and an iron block. After taking out the iron block, the water level drops by 4 cm. What is the volume of the iron block? If iron weighs 7.8 grams per cubic centimeter, how much does this piece of iron weigh?

Homework: Measure the volume of a sweet potato and a peanut.
