Which festival comes at the end of the year?

Here is the calendar for the month of February 2019. Let us mark a square on the calendar and see some magic.

Which is the number in the centre of the square?

How many such lines can you draw?

Add the three numbers on each of these lines. What do you notice?

5 + 13 + 21 = 

6 + 13 + 20 = 

7 + 13 + 19 =

12 + 13 + 14 =

Now look at the calendar of 2020. Also look for the present month and draw any similar square in your notebook. Does the magic work for these?

Is this magic possible on a 10 × 10 number chart? Go to the Chapter ‘Fun with Numbers’ and check.

See if this magic works for other lines which have five numbers. What about five numbers on a slanting line? Try this trick with your family and friends. Can you find other magic patterns in the calendar?
