(To the tune Yankee Doodle)
• When you have a word problem and it is sub-trac-tion,
• Always take the smaller number from the bigger num-ber.
• If you don’t have subtraction then you have ad-di-tion.
• Add the two numbers together and you get the ans-wer.
Lyrics to Yankee Doodle
• Yankee Doodle went to town riding on a po-ny.
• Stuck a feather in his cap and called it mac-a-ron-i.
• Yankee Doodle keep it up, Yankee Doodle dandy
• Mind the music and the step and let the girls be han-dy.
