9th garde in the FRC?

[yarden.saa]

Hi CD,
Personally I want the 9th graders to be in the FRC because the team will be stronger but our principal don't want it, she thinks they should be in the FLL.
I would like to get some claims why they should be in the FRC in order to convince the principal.
I have already told the principal that:
They are too old to the FLL
Our school can only have two FLL teams because of place and money problems so the FLL should be 7&8 grades and the FRC to the other grades...

I can't make see the whole picture, please help
