It's called "Summer Brain Drain" the two months worth of knowledge that kids lose over the summer.
Keeping kids academically busy over the summer is one answer, but it's not always easy and sometimes controversial.
Barbara Reyelts has that story in today's connect with kids report.
Some kids play during the summer break, and some like straight-'a' students mark and grace end up reading ... And reading ... And reading some more.
Not because they want to ...It's homework assigned by their school!
"The whole summer I'm not really just enjoying it and thinking school's out. I'm thinking 'Oh I have to read those books then go back to school.' "
"Ideally my summer would be where I got to do what I wanted to do and kind of not worry about academics so much."
Even some parents and educators agree.
"There's no time to recharge. It seem like a lot of their time is being sucked up."
"They need a break. Just like they need a break on weekends, they need a break in the summer. To be kids. Because I don't think we let them be kids."
Still, some experts say summer homework is a trend that's likely to continue.
And they recommend that parents explain to their kids that a little bit of homework isn't so bad and help them keep it in perspective.
"It was wonderful for that to be a relaxing time and I fully agree that all kids need time to relax. But they may not need two or three solid months of no exposure to books or information or math."
She says parents can help kids budget their time.
Even mark admits his summer homework would be less of a hassle if he did a little each day.
"But I usually cram it in on the last few weeks."
Experts say only if the summer homework load becomes so heavy that even if spread out over the summer, it interferes with other activities.
Parents should go to the teacher and express their concerns.
