Number Palindromes


This rich task is beautifully motivated through a series of conjectures and counterexamples, related to the strange “palindromification” of numbers. Take a number (i.e. 25), and add its reverse (52). Is the sum always a palindrome (77), that is, a number that reads the same forward as backward?


The video below explains how to use Number Palindromes to best effect in the classroom. See the PDF Lesson Plan for more.
