Specific teaching plan
I. Guiding ideology
Mathematics is a magical world, and there must be many students with strong interests. Therefore, it is most important to train students' thinking activities. A series of mathematical activities, such as thinking, reasoning and argumentation, are one of the theoretical bases for implementing thinking training in mathematics teaching. Therefore, the school-based Sudoku course can better promote the development of students' mathematical thinking ability and meet the requirements of curriculum reform; The second is to fill the weakness of our curriculum reform.
Second, the teaching objectives
1. Respect students' subjective position and personality, cultivate students' autonomy and initiative, and guide students to learn to learn and create in the process of mastering mathematical thinking results.
2. Put mathematics knowledge into the game, teachers should properly thread the needle, turn the monotonous mathematical process into artistic game activities, and let students learn in the game and gain in the play.
3. Around the word "fun" in class, put mathematics knowledge into activities, so that students can improve their ability of observation, imagination, analysis and logical reasoning in the process of seeking answers out of curiosity. Strive to embody the secret of our wisdom: "do math, play math, learn math."
Third, teaching measures
1, combined with teaching materials, select the teaching content of primary school mathematics to meet the needs of social development and further study. Strive to make the subject matter lively, diversified in form, balanced in solving problems and practical in teaching activities.
2. The choice of teaching content embodies the dialectical unity of teaching and learning. The presentation of teaching content is based on psychological knowledge, which accords with the unity of children's cognition and continuity, and makes the mastery of mathematical knowledge and skills consistent with children's thinking development ability.
3. The teaching content is lively, in line with students' age characteristics, inspiring, interesting and comprehensive, which can expand students' enthusiasm for learning mathematics.
4. Each mathematical thinking training class has a center, where there is discussion, communication and preparation. There is a stage of summary and reflection.

Lesson 1 The Origin of Sudoku
Introduction to Sudoku
This is an intellectual training. Literally, it is "single number" or "number that appears only once", which is a logical reasoning problem in the form of numbers.
Sudoku (Japanese: Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; Sudoku; A puzzle is a square with nine squares (that is, three squares wide by three squares high), and each square is subdivided into nine squares. Fill in the numbers of 1 to 9 in each small nine-square grid, so that the numbers in each column and row of the whole big nine-square grid are not repeated.
The logic of Sudoku is very simple, and the number arrangement is ever-changing. Many educators think that Sudoku is a good way to exercise the brain.
Teacher Magazine, the official education magazine of the British Ministry of Education, suggests that teachers should let students fill in Sudoku to train their brain wisdom.
In English schools, many math teachers have used this game which has little to do with math, but can train logical thinking ability. The teacher downloaded the game to the computer and asked the students to complete at least three Sudoku problems every week.
The World Sudoku Championship was held in Lucca in 2006 and has been held once a year since then. 20 13 was hosted by Beijing, China.
Lesson 2 Sudoku Basic Knowledge
First of all, the rules of Sudoku
There are 8 1 unit (nine columns and nine rows) in the ninth-order square matrix, which is divided into nine small squares (called palaces), and each palace has nine units.
There are generally only three rules for standard Sudoku:
1, the number of each row of Sudoku is 1-9 and it is not repeated;
2. The sudoku of each column is 1-9, which is not repeated;
3. The number of each house in Sudoku is 1-9, which is not repeated.
Second, the elements of Sudoku
The basic elements of standard Sudoku include cells, rows, columns, palaces, areas, blocks, known numbers, candidates and so on.
1, Cell: cell for short, it is the smallest cell on the Sudoku disk, and only one number can be filled in;
2. Line: the floorboard of 9 horizontal cells in Sudoku;
3. Column: the floorboard of 9 vertical cells in Sudoku;
4. Palace: the floorboard of 9 cells divided by thick lines on the Sudoku disk;
5. Region: a region filled with a set of numbers of 1-9, in which rows, columns and palaces are all concrete manifestations of the region;
6. Block: the floorboard of three parallel rooms in the palace;
7. Known number: the number originally given by Sudoku;
8: Candidate Number: the number that can be filled in an empty cell at present.
The above is related to the teaching plan of Sudoku problem-solving skills. It would be easy if we had a reference when writing a lesson plan. You can learn more about study and work online.
