PART II. ESSAY (8.0 points)

Exercise 1. (3.0 points) Solution Guide

a) In trực tiếp bóng đá hôm nay first 7 months of 2022, Vietnam provided trực tiếp bóng đá hôm nay most coffee to Spain (30.1%) and Indonesia provided trực tiếp bóng đá hôm nay least (5.5%).

b) i) trực tiếp bóng đá hôm nay amount of coffee supplied by trực tiếp bóng đá hôm nay German market to Spain in trực tiếp bóng đá hôm nay first 7 months of 2022 is: 222,956 × 12.6% = 28,092.456 (tons).

Similarly, we complete trực tiếp bóng đá hôm nay statistical table as follows:

ii) We can draw a column or line chart to represent trực tiếp bóng đá hôm nay data from trực tiếp bóng đá hôm nay statistical table above as follows:

c) trực tiếp bóng đá hôm nay amount of coffee that trực tiếp bóng đá hôm nay Vietnamese market supplied to Spain is

67,109.756 : 28,092.456 ≈ 2.4 times that of trực tiếp bóng đá hôm nay German market.

d) trực tiếp bóng đá hôm nay markets of Indonesia (5.5%) and Belgium (6.6%) are trực tiếp bóng đá hôm nay two smallest coffee suppliers to Spain in trực tiếp bóng đá hôm nay first 7 months of 2022.

Vietnam supplied 24.6% more coffee to Spain than trực tiếp bóng đá hôm nay Indonesian market: 30.1% - 5.5% = 24.6%.

Therefore, trực tiếp bóng đá hôm nay article's information is accurate.

Exercise 2. (1.5 points)

What arepractical and experiential activities in trực tiếp bóng đá hôm nay 8th-grade Mathematics curriculum in Vietnam?

Under trực tiếp bóng đá hôm nay General education program in Mathematics issued withCircular 32/2018/TT-BGDDT, trực tiếp bóng đá hôm nay 8th-grade Mathematics curriculums have trực tiếp bóng đá hôm nay following practice and experiential activities:

trực tiếp bóng đá hôm nay school organizes some of trực tiếp bóng đá hôm nay following activities for students and might include other activities depending on specific conditions.

Activity 1:Learn some financial knowledge such as:

- Creating a personal spending plan.

- Becoming familiar with personal investment problems (determining investment capital to achieve desired interest rate).

- Understanding bank statements (actual statements or examples) to identify transactions and track income and expenses; choosing suitable payment methods.

Activity 2:Practicing trực tiếp bóng đá hôm nay application of mathematical knowledge in real life and interdisciplinary topics, for instance:

- Applying Algebra knowledge to explain some rules in Chemistry, Biology. Example: Using first-degree equations in problems to determine percentage concentrations.

Activity 3:Organizing extracurricular activities such as outdoor practice, study projects, math games, math contests, for instance:

- Searching for or practicing creating video segments on trực tiếp bóng đá hôm nay application of pyramids, perspective similarity in nature.

- Applying knowledge about similar triangles and trực tiếp bóng đá hôm nay Pythagorean theorem in practice (e.g., measuring trực tiếp bóng đá hôm nay distance between two positions with an obstruction or accessible by one of trực tiếp bóng đá hôm nay two).

- Practicing calculating trực tiếp bóng đá hôm nay area, volume of certain shapes and solids in reality.

Activity 4 (if trực tiếp bóng đá hôm nay school is capable):Organizing exchanges with students who are capable and passionate about Math within trực tiếp bóng đá hôm nay school and with other schools.

What is trực tiếp bóng đá hôm nay core content of trực tiếp bóng đá hôm nay 8th-grade Mathematics curriculumin Vietnam?

Under subsection 1 of Section 5 of trực tiếp bóng đá hôm nay General education program in Mathematics issued withCircular 32/2018/TT-BGDDT, the8th-grade Mathematics curriculum in Vietnam outlines trực tiếp bóng đá hôm nay core content as follows:

- trực tiếp bóng đá hôm nay content of Mathematics revolves around three strands: Numbers, Algebra and Some Analytic Elements; Geometry and Measurement; Statistics and Probability.

- Numbers, Algebra and Some Analytic Elements form trực tiếp bóng đá hôm nay basis for deeper studies in mathematics, to create mathematical tools to solve problems in mathematics and related sciences; developing deductive reasoning, logical thinking, mathematical creativity, and algorithm skills in students.

Functions are also a crucial tool for constructing mathematical models of processes and phenomena in trực tiếp bóng đá hôm nay real world.

- Geometry and Measurement are essential elements of mathematics education, crucial for students in acquiring spatial knowledge and developing essential practical skills.

Geometry and Measurement create tools to describe objects in trực tiếp bóng đá hôm nay surrounding world, provide students with basic mathematical knowledge and skills in Geometry, and enable them to perform mathematical proofs, contributing to developing logical thinking, creativity, spatial imagination, and intuition. Moreover,

Geometry contributes to aesthetic education and enhancing students' math culture. trực tiếp bóng đá hôm nay integration of Measurement with Geometry increases trực tiếp bóng đá hôm nay intuitiveness and practicality of teaching Mathematics.

- Statistics and Probability are compulsory parts of school mathematics education, enhancing trực tiếp bóng đá hôm nay applicability and practical value of mathematics education. Statistics and Probability equip students with trực tiếp bóng đá hôm nay ability to perceive and analyze information presented in various forms, understand trực tiếp bóng đá hôm nay probabilistic nature of many dependencies in reality, and comprehend trực tiếp bóng đá hôm nay vital role of statistics in providing socially significant information, applying statistical thinking to data analysis. Thus, improving students’ understanding and methodology for researching trực tiếp bóng đá hôm nay modern world.

- Additionally, trực tiếp bóng đá hôm nay Mathematics curriculum at each level allocates appropriate time for students to engage in practical and experiential activities such as: Conducting research projects on Mathematics, especially projects on trực tiếp bóng đá hôm nay application of Mathematics in practice; participating in math games, mathematical clubs, forums, workshops, and competitions; creating math journals; visiting mathematics training and research establishments, interacting with students with a talent and passion for Mathematics, etc.

These activities help students apply trực tiếp bóng đá hôm nay knowledge, skills, attitudes accumulated from math education and personal experience in real life creatively; develop organizational and management skills, self-awareness, and self-activation; assist students in identifying their abilities, strengths for career direction, and creating basic competencies for future workers and responsible citizens.
