Numbers

A song based on the writing of seventh grade students. Students did the following:

  • Second grade students read the story Who's the Big Bad Wolf?
  • They explored the math in the story (using snap cubes)
  • They practiced telling stories they could share at home about the math experience
  • They drew pictures and wrote to descibe what they learned
  • Their writing was compiled to create three songs
  • Their seventh grade math buddies then came to their class and:
    • The second graders read them the story
    • They explained the math they learned
    • Then they sang their songs
  • The seventh graders then went to their class and used concrete materials to model and then to write algebraic expresions for the sums of the first N odd, even and Natural numbers.
  • Then the seventh graders wrote and sang a song to the second graders

Numbers

1, 3, 5, 7, 9
All these numbers hurt my mind
The sum of these
Is 5 by 5    [NxN]
 
2, 4, 6, 8
Who do you appreciate
N times N plus 1     [Nx(N+1)]

1, 2, 3, 4, 5
The sum of these is alive
Take the even numbers
And divide by 2     [Nx(N+1)/2]

We all like algebra
We see patterns everywhere
