In this activity, we will learn how to fill in missing numbers in magic squares.
Example
Fill in the missing numbers in this magic square.
| 3 | 4 | |
| 1 | 5 | |
| 7 |
Answer
Each row, column and diagonal must add to the same amount (the magic total).
The clue here is that we have 3, 5 and 7 in a column, which means that the magic total is 3 + 5 + 7 = 15
Use this fact to complete the square using addition and subtraction.
| 8 | 3 | 4 |
| 1 | 5 | 9 |
| 6 | 7 | 2 |
Let's try some ourselves now.
