Has your high school student just finished first term? Is his/her home workspace cluttered with the remnants of first term study?
Do everyone a favour, especially your student, and help them purge out the first term to make room for second term. The longer you leave the remnant clutter hanging around, the less likely it is to be sorted and purged before chaos sets in. Help your student sort through the notes for relevant material to keep such as key assignments and throw out the rest.
Helping students purge on a timely basis helps them learn sorting and prioritizing skills for their “office” before material becomes clutter. In addition, you will be teaching them the value of a clear, uncluttered space. They will be able to focus on the task at hand (second term’s material).
You’ll both feel better.
