I see a lot of people referencing what was done when they were children, ect. When I was in school, we took a week off without a problem almost every year, but times have changed. The material kids are seeing now is vastly different than what we were asked to do.
We didn't learn long division until 5th grade, but DD was doing it at the end of 2nd. We didn't write 5 paragraph persuasive essays with evidence in elementary school ,but she had to starting in 3rd grade, timed, as part of state assessments.
When I was in high school, you could graduate without ever taking algebra, now every student is enrolled in algebra as a freshman. The demands placed on me as an AP student in the 90's are vastly different that those placed on my DD who is an IB diploma student now. She is taking courses as a Sophomore that weren't even offered at the high school level when I was in school. She has already taken and passed AP exams that didn't exist when I was in school. I was in the top of the line, most demanding program available at the time, but what is she is being asked to do is worlds ahead of what i saw in high school. Her nightly work load is many times what mine was.
The demands placed on kids have stepped up. I am not saying don't take your kids out, just that its important to be mindful of what it is going to mean work wise for them. Particularly for students in advanced academic programs post elementary school.
