If you haven’t seen the meme going around, this is a palindrome week because the dates (written American style and with the year shortened to ’19) are the same when reversed.
Here’s a math puzzle for palindrome week:
Print a 100 chart.
Choose a color code.
- What do you think: Will all numbers eventually turn into palindromes?
You can find all sorts of hundred charts on my Free Math Printable Files page.
Read about the history of palindromes on Nrich Math’s Palindromes page.
Find out more about the Palindromic Number Conjecture in Mark Chubb’s article An Unsolved Problem your Students Should Attempt.
Or play with Manan Shah’s advanced palindromic number questions.
I created these coloring pages for my homeschool co-op math kids, and then collected them into a downloadable 42-page PDF coloring book for your family to enjoy.
The booklet includes several ready-to-color designs, a wide assortment of graph paper, advanced create-your-own tessellation pages, and links to all sorts of online math art resources.
But when I posted the link to Twitter, a friend noticed that several of the resource links were broken. (Thanks, Mark!)
While I was fixing those, I added some new links (to the wonderful School of Islamic Geometric Design pattern templates and classroom resources).
So even if you’ve downloaded the file before, you may want to pick up this new-and-improved edition.
