A palindrome is anumber that reads the same backwards as it does forwards. The number 2332 is an example of a palindrome. Read either way the number is the same.

To Make A palindrome, add any number to its reverse. If it is not yet a palindrome, reverse the didgets and add it to the answer. Continue reversing and adding until the answer becomes a palindrome.

The example on this card, 57, is a two-step palindrome because it is reversed and added two times to become a palindrome.    57
                                      + 231

Work as a group to find all the numbers between 10-50 that can make a palindrome in two steps.
