Look at the patterns of numbers in hexagons.
Each side has 2 circles and 1 box.

• Look at the number 65 in the box. Which are the circles next to it?
• Can you see how the rule works?

Use the same rule to fill the hexagons below.

Now you also make your own magic hexagons.

Now let s use words in a special way.

Did you notice that it reads the same from both sides — right to left and left to right?

Now try and use words in a special way.

Look at the calendar below.

Let us mark 3 × 3 boxes (9 dates) on the calendar and see some magic.

       1      = 1 × 1

     121    = 11 × 11

   12321  = 111 × 111

1234321 = ?

Now make your own number surprises.
