Answer:
1. Students lose mathematics and reading knowledge over the summer (harm)
2. This study found that the average student lost 17–34% of the prior year's learning gains during summer break, as well as that students who lose ground in one summer are more likely to also lose ground in subsequent summers.
3. Students have more opportunities during the summer were they can do physical activities, get a job, practice their social skills and get a break from the stress that school causes.
