Logic Dog Big Class Computing Game 1 Teaching Plan

1. In the "calculation game", feel the relationship between the numbers in the three areas of the triangle and the three results around it by putting in the disk and filling in the appropriate numbers.

2. Solve problems in computing games by trying, checking and correcting.

Teaching focus

Explore the relationship between the numbers in the three areas of the triangle and its three surrounding results in the "calculation game" and solve simple problems.

Teaching difficulties

Solve problems in computing games by trying, checking and correcting.

teaching process

Oral calculation: exercise book page 3, question 1.

First of all, know the triangle number graph.

1, brief introduction of triangular graph.

Teacher: This is a triangle.

Q: What secrets did you find in this triangle figure? Students communicate in groups on the basis of independent thinking.

Teachers and students * * * the same summary: the triangle figure has three parts, each part has a small disk, and the number of small disks in adjacent parts is added up, and the result is written on the side.

Secret topic: Today, we are going to learn "Calculation Game" (blackboard writing topic).

Second, explore the triangle number diagram.

1, explore a.

Small disks or numbers are placed in all three areas of the "calculation triangle".

Search: 3 results.

Students can put their own CDs on the sketch of the calculation triangle and calculate the results. Cooperate at the same table to play "triangle disk"

One person puts a small dish on the triangle, and the other person puts a few cards according to the small dish. )

Report.

2. Investigation 2

Small plates or numbers were put in Zone 2, and 1 result numbers were given in advance.

Exploration: Put an appropriate number of disks or sums in the 1 area and find two results.

(You can calculate the number of disks in the third area and the other two results by addition and subtraction. )

3. Exploration III

1 area has been released or numbered, and two result numbers are given in advance.

Exploration: Put an appropriate number of disks or numbers in two areas to find the third result number.

(It can be calculated by addition and subtraction. )

Complete question 2 on page 3 of the workbook.

4. Exploration 4

All three areas are empty, and three result numbers were given in advance.

Exploration: Put the disc in three areas correctly, and get a preset number of results on three sides.

Complete question 3 on page 3 of the workbook.

Fourth, summary.

Teacher: What did you gain today? What skills have you learned?
