# 12 Days of Presents

December 25, 2020

(Note: As we do on special holidays, in honor of today we’re providing a second extra math problem about Christmas, for those who celebrate or would like to learn more about it. Enjoy!)

Christmas is a very special day for Christians, as it’s the birthday of baby Jesus. But Christmas starts a whole 12 days of celebration ending with the Epiphany, the day the Wise Men brought gifts to their newborn King. In the old days, people gave gifts on all 12 days. So of course someone wrote a song about it, “The Twelve Days of Christmas.” Many of the gifts are either birds — geese a-laying, swans a-swimming, or that partridge in a pear tree. And those gifts add up FAST. Remember, on the first day of Christmas you get a partridge, then on the 2nd day you get 2 turtle doves AND a partridge, then on the 3rd day 3 French hens AND 2 more turtle doves AND another partridge…we hope you also got some birdcages for Christmas!

Wee ones: On the 2nd day of Christmas you get 2 turtle doves and a partridge in a pear tree. How many birds do you get that day?

Little kids: On the 3rd day of Christmas you get 3 French hens, 2 turtle doves and a partridge in a pear tree. How many birds is that?  Bonus: If you wanted to split the birds into 2 equal groups but keep each with its own kind, how would you do that?

Big kids: On day 5 you get 5 golden rings, and you get a whole new set of 5 on each of days 6, 7, 8, 9, 10, 11 and 12. How many rings do you get in total?  Bonus: If each ring weighs a whole ounce in gold and gold costs \$2,000 per ounce, how much do all those rings cost?
