Did you know? Research says that kids need to read four or more books over the summer to stay on top of language arts skills and avoid remedial work when they return to school in the fall. There's no better way to meet that goal than to get them hooked on an addictive series.

Series books offer a scaffolded approach for emerging readers, helping them to feel confident and successful. And there are so many terrific options in bookstores, from series that tickle the funny bone to fast-paced adventure and fantasy.

Read on for some of our favorite choices. Then go to scholastic.com/summerreading for more book lists and information on stopping the summer slide.

What Was Your Favorite Series?
We asked Instructor readers and editors to share their favorite series growing up.

"I was a huge Nancy Drew fan-one time in fifth grade I had checked one out of our school library. I'd had it for a few days and was almost finished with it by the time the dismissal bell rang. I stood outside the library reading the last few pages so I could dash in and check out the next one, and ended up missing my bus!"  — Natalie Lorenzi

"So many come to mind, but I adored The Borrowers by Mary Norton. Sometimes I still think The Borrowers could be living in my apartment, especially when I can't find my keys!"  — Hannah Trierweiler Hudson

"I loved the Sweet Valley Twins. It was such a fun escape-the thought of having a twin sister was really cool to me, and they lived in California, which also seemed cool."  — Jessica Rosevear
