Specific Teaching Program

I. Guiding Principles

Mathematics is a magical world, and many students must have a strong interest in it. For this reason, the training of students' thinking activities is the most important. Mathematical thinking activities in the mathematical teaching classroom to explore the problem of thinking, reasoning, the process of argumentation and a series of mathematical activities are one of the theoretical basis for the implementation of thinking training in mathematics teaching. Therefore, to carry out school-based Sudoku course, one can better promote the development of students' mathematical thinking ability, in line with the requirements of the curriculum reform; two is to fill the weakness of our curriculum reform.

Second, the teaching objectives

1, respect for the student's subjective position and the main personality, to cultivate students' autonomy, initiative, and guide students in the process of mastering the results of mathematical thinking in the process of learning, learning to learn to create.

2, the mathematical knowledge in the game, the teacher appropriate threading, the monotonous mathematical process into an artistic game activities, so that students learn in the game in the game harvest.

3, the classroom around the "interesting" word, the mathematical knowledge in the activities, so that students in the curiosity, in the pursuit of answers to the process of improving their ability to observe the ability to imagine the ability to analyze the ability to reason logically. Strive to reflect our wisdom secret: "do math, play math, learn math".

Third, teaching measures

1, combined with the textbook, selected elementary school mathematics teaching content to adapt to the needs of social development and further learning. Strive for the content of the subject matter of life, the form of diversification, the solution to the equation of ideas, teaching and learning activities in practice.

2, the selection of teaching content reflects the dialectical unity of teaching and learning. The content is presented on the basis of psychological knowledge, in line with the unity of children's cognition and continuity, so that the mastery of mathematical knowledge and skills and the development of children's thinking ability to be consistent.

3, the form of teaching content is lively, in line with the age of students, giving inspiration, fun and comprehensive, can expand the students' motivation to learn mathematics.

4, each mathematical thinking training class has a center, there are discussions and exchanges have been prepared. There are stage summaries and reflections.

Lesson 1: The Origin of Sudoku

I. Introduction to Sudoku

Sudoku is a kind of intellectual sport. Literally, it means "a single number" or "a number that appears only once", and it is a kind of logical reasoning puzzle in the form of numbers.

Sudoku (Japanese: 数独すうどく) is a number puzzle that originated in Switzerland at the end of the 18th century, was developed in the United States, and flourished in Japan. The puzzle is a square with nine squares (3 squares wide x 3 squares high), each of which is subdivided into nine squares. In each of the small nine squares, fill in the numbers 1 to 9, so that the whole big nine squares of each column, each row of numbers are not repeated.

The logic of Sudoku is simple, and the numbers are arranged in many different ways. Many educators believe that Sudoku is a great way to exercise your brain.

Teacher Magazine, the official education magazine of the Department for Education and Teaching in the United Kingdom, suggests that teachers should let their students fill in Sudoku to train their brains.

Many math teachers in British schools are using the game, which has little to do with math but trains logical thinking skills. Teachers download the game to their computers and ask their students to complete at least three Sudoku puzzles a week.

The World Sudoku Championship was held in Lucca, Italy, in 2006, and has been held annually since then, with Beijing, China, hosting the event in 2013.
