I wrote this song for my elementary math classes to help teach that commas go after every 3 digits in a number. Use this along with my 'reading numbers' place value song: http://youtu.be/963IUfaH7b0 See more of my math and science resources: http://mathstory.com Lyrics There's a comma that you need in a number, If your number has more than 3, DIGITS!!! There's a comma that you need in a number, To make your number easy to read! HIT IT!!! Say 1-2-3, POW! The comma goes after three, Starting from the right, Moving to the left, It's really very easy you see... Say bop-bop-bop BANG! The comma goes after 3, Starting from the right, Moving to the left, It's really very easy you see... 1-2-3, Thousands 1-2-3, Millions Every three digits, That's how commas go! 1-2-3, Thousands 1-2-3, Millions Every three digits, That's how commas go! The first comma separates, The hundreds from the thousands, It makes them easy to read... The second comma separates, The thousands from the millions
