My dd1 has switched to a charter middle/high school combo this year for 6th grade and I'm finding the homework load to be quite a step up from 5th grade.
Just the end of this week (Thurs and Fri) she had a 1 page paper due for Science with at least two sources, a reading packet for Science with questions to answer and vocabulary words for Science to define, a book report due for English, a journal due for English (due at the end of each month), printing out 3 favorite poems for English, a vocabulary packet due for English, math homework (I didn't see it, my DH helped her, but it was a write the equation for this and then solve it), studying for a Social Studies test on Friday and studying for an English test on Friday. Over the weekend she has a paper to write for an elective class, and math homework.
Whew. I'm tired just looking at that. There is a study hall period built into everyone's schedule where they can work on their homework and get help from the teachers if they need it. I'm definitely encouraging her to use that so she can reduce the load she brings home, but some nights it's just oppressive.
Now, they do almost always give them a few days to complete an assignment so dd1 got the Science homework on Tuesday and it wasn't due until Thursday, but other classes also give homework during that time. She's learning to manage her time and not save it all up until the night before it's due, but it's still a heavy load. She did the paper for Science on Tuesday and the reading packet on Weds, but she still had all the English and Math due. She does occasionally get Social Studies homework, but thankfully not as much.
My dd2 is in 3rd grade and just has a one page math worksheet, often with just one big word problem to solve and then you have to write down an explanation for your work. She does it in about 5-10 minutes and then has to amuse herself for hours while we keep dd1, who has some focus issues, on track on her homework.
