# The Twelve Days of Christmas

## How many gifts did my true love send to me altogether?

First verse:
O
n the first day of Christmas,
my true love sent to me
A partridge in a pear tree.

Last verse
O
n the twelfth day of Christmas,
my true love sent to me
Twelve lords a-leaping,
Ten pipers piping,
Nine drummers drumming,
Eight maids a-milking,
Seven swans a-swimming,
Six geese a-laying,
Five golden rings,
Four calling birds,
Three French hens,
Two turtle doves,
And a partridge in a pear tree!

There are 12 verses altogether.

## Video

This awesome version of the song by Pentatonix will make even Ebeneze Scrooge feel festive and join in the harmonies!

## Music

Here is an instrumental version to have playing quietly in the background while working on this Starter in the classroom.

• You may need to give the pupils a little help if they are having difficulty. Can you sing? Well if singing is out of the question the song could be recited as a poem. Once pupils start making a list of the total number of presents each day they will see the pattern of triangular numbers emerge. Could they generalise this to find the number of presents received on the nth day? More advanced students might consider finding the formula for the sum of the series!

• Ideas for further developing this theme:

How many birds are there?
How many people are there?
If each drummer has 2 drumsticks how many sticks are there altogether?
If each goose lays 2 eggs and each of the other birds lay 3 eggs how many eggs would there be?
How many eyes are there altogether?
If the gold rings were shared out amongst the maids how many would not have one?
How many people are playing a musical instrument?
How many fingers are there altogether?
Could all the birds be shared out equally between the ladies dancing?

• Each year the PNC Christmas Price Index estimates the cost of buying all of the gifts in the song. In December 2021 it was estimated to be £30,562 (US \$41205).
