## Free worksheet – Counting the Twelve Days of Christmas

How about a little math twist on a familiar Christmas carol? I am sure we are all familiar with the “Twelve days of Christmas”, but has it occurred to you that the number of presents that “my true love sent to me” is a sequence of Triangular Numbers? In this free worksheet, you’ll be asked to count the number of gifts you will receive on each day (there is a trick to it) and the total number of gifts you will receive up to the n-th day. Suggested solutions are provided at the end (don’t peek).
