Develop More Advanced Reading Skills! For kids who can read words with 5 or more sounds—like split.  As kids’ reading confidence builds, they naturally want to read “big kid” books. But most of those books are just too tough! These reading-science-backed books meet kids right in the middle to help them grow their confidence in sounding out (decoding) trickier words. The books and pages are a bit longer, so they’ll feel like “real” readers! The included parent guides equip you to support your child’s new skills.
