TwERL Phonics for tweens (middle school phonics) has been developed specifically for emerging, striving readers in grades 4–8 who are developing their decoding skills. The series is also useful for newcomers with no prior English language skills. Written at emergent and beginning reader levels, the books are carefully controlled to showcase phonics skills, starting with CVC words and progressing through long vowels, consonant digraphs, vowel diphthongs, and multisyllabic words. Accompanied by dynamic, full-color photos, the engaging storylines are tween-centric and span a wide range of genres.
