I have always struggled with teaching my students their multiplication facts, especially the 3's, 4's, 6's, 7's, and 8's. I put the multiples to the lyrics of simple songs (Row, Row, Row Your Boat, Happy Birthday, etc.). Seriously, the best thing I have done in my math class. My kids actually know their facts! It is only $2 and even if you don't sing... you can always have a "math choir" lead your class. I promise it will be worth your time!
