In this activity, we will learn how to fill in missing numbers in magic squares.
Fill in the missing numbers in this magic square.
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.
Let's try some ourselves now.
