No, I didn't come up with that term, but you hear it all the time now. Kids lose some of what they learned all year when they don't practice their skills over the summer. If you are like me, I am not great at coming up or convincing my kids to do random work so when my friend showed me these workbooks I was all about it. We just started them and I like them a lot. They have all the grade levels and cover lots of subjects!!!
