How many days have I lived?

As part of our activities exploring what a birthday we talked about how a day is one turn of the earth and a year is one whole orbit of the earth around the sun. I played the sun and Builder Boy spun around while I guided him in an orbit around me six times.  365 is a big number to comprehend, so I made pages of 365 (or 366 for leap years) squares on a page; one page for each year, to show how many days he has been alive.

I don't know how to share documents on the blog, so I turned them into jpgs to share. You can copy and paste to make your own.

(Link to a list of leap years.)
