Subject: Re: Mathematical Palindromes for Elementary Ed.
Dear Sarah, Palindromes themselves may not be such an important topic but they do provide a vehicle to teach other topics which ARE more important to elementary education. Here's a thought for a possible activity. Ask the question how many palindromes two- and three-digit palindromes are there? Using number tiles, the students could construct them. They will more than likely run out of tiles before they find them all, so they'd have to work on recording the palindromes in a list. To make sure they found all of the palindromes, they could work on making a systematic list. If they are asked to tell you what palindrome they found, they could work on reading the numbers out loud (two hundred two instead of two oh two). There are number puzzles you could create involving palindromes. "I am thinking of a 3 digit palindrome. The ones digit is even. The hundreds digit is greater than 7. The tens digit is the sum of 1 and 8. What is the secret number?" (This may not be 2nd grade appropriate, but I am hoping you get the idea.) To do this puzzle, the student has to know lots of vocabulary, know the place values, and number relationships. Hope this helps. -Jeanne, for the T2T service
