Mathematics Overview Students make generalizations from patterns and practice reading large numbers and addition with regrouping. A palindrome is a number that reads the same forward and backward, such as 44 or 252 or 8008. Record how to do this on the board.
Some numbers take more than one addition.
Students should decide how to divide up the work within their group and how to keep records of their information. These numbers each take 24 steps. Some groups notice, for example, that when the sum of the digits of a number is less than 10, the number is always a one-step palindrome. Others notice that all resulting palindromes are multiples of 11. Give students a number from 0-99 and have them use the chart or table that their group created to describe its behavior when making a palindrome.
