A new birthday song with some maths - simply adding 1 more

Thursday, 8 October 2015
It was interesting to see the 'Happy birthday to you...' song in the headlines - after 80 years of charging royalty fees it is now free to publish in the US. It could not be used in maths books before, so some years ago I made up a new birthday song that included adding one more.
In 1996 when writing the Longman Primary Maths scheme, we wanted to include a ‘Special Days’ section in the Reception teachers book, which obviously included birthdays.
 
The publishers didn’t want to include the ‘Happy birthday to you…’ song for copyright reasons, but I didn’t want to include it because I thought it was just a poor song for children’s birthdays.

So, with the help of my wife and 8-year old daughter, we came up with an alternative birthday song for the book. I wanted the age included, and the fact they were 1 year older so it reinforced the numbers. I trialled it at my school and they liked it so much they actually kept it as their birthday song in assemblies.

Here it is, to the tune of ‘Frere-Jacques’:

One year older,
One year older,
5 today,
5 today,
Have a happy birthday,
Have a happy birthday,
Celebrate,
Celebrate!


If you want to try it, I’ll give you permission and won't ask for any copyright fees!


The children held up one finger to show one year older, and five fingers (or however many) for the age. We got quite sophisticated as well, singing it in the round (always a good thing about ‘Frere-Jacques’).

You can also use a number fan instead of fingers, start with holding yesterday's age, then sing one year older and change it their new age to match the third line. 

Birthday activities for KS1

Integrate simple data handling by having two sorting circles for children who are 4 or 5 and then a month by month tally-style record showing how many birthdays in each month.  Move each person from four to five on their birthday. 
Birthdays

Birthday activities for KS2


Statistics can be introduced in the same way for KS2 but with block graphs for each month to show the number of birthdays. 
Reinforce place value by asking them to show 10 more, 100 more or 1000 more years than their age. 

Use the current year, age and year of birth to make a trio. 

                          2015
               9                       2006


2015 - 9 = 2006       2006 + 9 = 2015

2015 - 2006 = 9       9 + 2006 = 2015
Generate calculations and word problems:

Lower KS2 - What year will it be when you have your 21st birthday? [or 13th, 18th, 50th?]

Upper KS2 - ​ How old will you be in on your birthday in 2050? 2035? If I was born in 1977, how much older am I than you?

If the correct number of candles are bought every year for a child's birthday cake, how many candles would have been used in total by the time the child is 10, 21, 50 or 100?
