Sudoku PPT, Part 2: Classroom Analysis

In the square on the right, each row and column has four numbers from 1 to 4, and each number appears only once in each row and column. What should B be?

I know that each row and column has four numbers from 1 to 4.

I also know that each number appears only once in each row and column.

What problem are we trying to solve?

What should B be?

Where should we start to solve this problem?

First look at which blank row and column have three different numbers, so that you can determine the number that should be filled in this blank.

3, 1, and 2 already appear in the row and column where A is located.

First look at which blank row and column have three different numbers, so that you can determine the number that should be filled in this blank.

How much is B? What should I think?

A is 4, so 4, 2, and 3 already appear in the row and column of B.

Sudoku PPT, Part 3: Classroom Practice

1. In the above square, each row and column has four numbers from 1 to 4, and each number appears only once in each row and column. What should B be? What about the numbers in the other squares?

Looking at the row and column where B is located, 4, 1, and 2 have appeared, so B is 3.

I start from A, and the row and column where A is located already have 4, 2, and 3, so A is 1.

2. In the square below, each row and column has four numbers from 1 to 4, and each number appears only once in each row and column. What should B be?

B should be 3.

3. Choose appropriate numbers from 1 ~ 9 and fill them in □ below (the numbers in each equation cannot be repeated).

When filling in the numbers in the square (4×4), first look at which row and column of the blank have three different numbers, so that you can determine the number that should be filled in the blank, and so on. Able to fill in the numbers in the square completely.
