2. Assuming that all 17 stamps are 4-cent stamps, then 8-cent stamps are:

(100-17× 4) ÷ (8-4) = 8 (sheets)

Then an 8-point stamp is 17-9=8 (sheets), and the difference is 9-8= 1 (sheets).

Or suppose that 17 stamps are all 8-point Rightists, then 4-point stamps are:

(17× 8-100) ÷ (8-4) = 9 (Zhang)

Then four stamps are: 17-9=8 (sheets), and the difference is: 9-8= 1 (sheets).

examination paper analysis

Characteristics of test paper proposition:

1, choose realistic and vivid materials.

Adapting some materials closely related to real life into innovative test questions, causing students to find and solve practical problems. Let students realize the application of mathematics in life.

2. Create a platform for independent choice. The first network of new curriculum standards

In order to choose new background materials and change the style of the topic structure appropriately, the test questions provide students with more opportunities for independent inquiry. For example, the Fifth Avenue issue.

3. Pay attention to the content of mathematical thinking.

Some questions let students observe, analyze, summarize and discover the mathematical laws contained in them, which not only apply what they have learned, but also cultivate students' application consciousness.

This test focuses on the process derivation of mathematical knowledge. In the classroom, students learn a comprehensive and systematic knowledge system, implement various knowledge points, give full play to the role of knowledge, conduct thinking training, and let students experience the process of knowledge acquisition. It is necessary to fully reflect the thinking value of excavating mathematical knowledge deduction process and carry out systematic teaching.

Pay attention to the implementation of basic knowledge. Basic knowledge is what students, especially those with learning difficulties, must master. Teaching can't be superficial, but must be dug deep to reflect ideas.

Teaching pays more attention to learning methods and strategies. When encountering different types of exercises, let students find more suitable solutions and strategies to improve their problem-solving ability, and finally establish a problem-solving model and develop their thinking ability.
