Free Prime Number Birthday Cards

Dear Chicago House,

I celebrated a birthday last week and on waking up that morning, I rolled over and told Mr Chicago “I am in my prime!”

This was a serious “geek alert” moment as I was referring to prime numbers. Is it a little worrying I was thinking about mathematical concepts as soon as I became conscious? Mr Chicago replied …there is the making of a birthday card in that statement. And so the seed was sown…time to put on my graphic designer hat. If you need a little refresher course on what a prime number is click here.

So if you are looking for a birthday card for someone celebrating a prime number birthday and who’d appreciate this fun mathematical fact here you go.

I have created cards cards for 7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89 and 97 year olds. I figured 2,3 and 5 year olds were unlikely to get it!

Here is a quick sample of the cards… Links for each card are below

Enjoy!

That is a seriously fun idea for all the math and numbers people out there. Brilliant!!

this is great – ty!

Thank you for these. My friend, who’s a math professor who just turned 67, will appreciate this at his party coming up later this month.

75 is not a prime number (it is divisible by 3,5 …) However it would be an interesting age to make a card for!
