Three Is A Magic Number

Three Is a Magic Number: School House Rock video about multiplying by Three. Lyrics from http://www.school-house-rock.com/3.html It takes three legs to make a tripod or to make a table stand It takes three wheels to make a vehicle called a tricycle Every triangle has three corners Every triangle has three sides No more, no less You don't have to guess When it's three you can see it's a magic number A man and a woman had a little baby Yes, they did They had three in the family And that's a magic number 3-6-9, 12-15-18, 21-24-27, 30 3-6-9, 12-15-18, 21-24-27, 30 Now, the multiples of three Come up three times in each set of ten In the first ten you get 3, 6, 9 And in the "-teens" ten it's 12, 15, and 18 And in the "twenties" you get 21, 24, 27 And it comes out even on 30 Now multiply backwards from three times ten 3 x 10 is 30 3 x 9 is 27 3 x 8 is 24 3 x 7 is 21 3 x 6 is 18 3 x 5 is 15 3 x 4 is 12 And 3 x 3 is 9 And 3 x 2 is 6 And 3 x 1 is 3 of course Now dig the pattern once more Three! 3-6-9 Twelve! 12-15-18 Twenty-one! 21-24-27, 30 Yeah, thirty Now multiply from 10 backwards 3 x 10 is 30 (keep goin') 3 x 9 is 27 3 x 8 is 24 3 x 7 is 21 3 x 6 is 18 3 x 5 is 15 3 x 4 is 12 And 3 x 3 is 9 And 3 x 2 is 6 And 3 x 1...
