"Change For A Dollar" is a four minute, karaoke style music video, that students can sing along with to help learn about decimal place value. It focuses on the tenths and hundredths places, and how they represent dimes and pennies. This would make a good introduction to decimal place value, or another way to reinforce and review the concept.
I use it with my sixth graders as a review or "Math Starter." The 4th and 5th grade classes at my school also use this song.
