Re: The ruler thing... DD8's teacher taught her class to line the end of the ruler up at the end of the line they were measuring, instead of lining it up at zero. Worked fine up to nearest half inch, but no one could figure out why the answers were suddenly all wrong for quarter inch...
This teacher has been teaching third grade longer than I've been alive.
