mountainmom, I don't know about any laws, but is there any chance you have a parents advocate group local to you that you could ask this question? Also have you tried talking to your school district's SPED coordinator? I think it's worth at the very least an email question to the SPED coordinator asking how this situation is usually handled. Have you tried asking on wrightslaw?
If your Monday morning meeting isn't helpful, I'd request an emergency IEP team meeting to address the issue.
Sorry I'm not much help! I hope you're able to work out a schedule that doesn't require her to miss classroom instruction in other subjects.
Best wishes,
