Take her out
I am in Texas and have never had a problem taking my kids out of school to go to WDW.
We just returned from WDW this February and our kids where out for 5 days. I have a daughter in7th grade, a son in 4th grade and a daughter in Kindergarten. We where able to get some of their work for them to do on the way down and the rest they just made up when they returned.
Our school system even has 2 days a year for "parent day." As long as they are with us it is considered an excused absence.
Although 2nd grade is important, there can't be that much covered in a weeks time that can't be caught up on.
My kids are good in school and they understood that the vacation came with it's "drawbacks", ie..extra homework for a while, but they understood that and didn't have a problem with it.
4 of our last 5 trips to WDW have been during school. You should see how many kids are at WDW on a daily basis and not in school somewhere.
I would check your student manuel or with the school board about the policy of missing school. Not just for a vaction, but for whatever. Just tell them that you are going to be out of town for a week and need the assignments.
If they refuse to allow any of the days to be excused, check into how many days she can miss for the year and see if it will be under that. Sick days are excused in Texas and they are allowed 9 unexcused for the year. My kids normally only miss if they are sick anyway so no loss there.
I say take her out, if, she is good in school and understands that she will have a little extra work to do when she returns. Even if they don't give you the assignments ahead of time, go and enjoy your vacation.
PS......Sounds like a teacher could be jealous of your child going to WDW or maybe because all of the class can't go. Hey that would be a great field trip.:lol:
