This easy-to-use program delivers differentiated instruction, tailored to students’ individual needs, in the context of a digital learning environment.

This translated to better fluency and confidence for my resource language arts students. When students took the WordFlight™ seriously and committed their time and attention, they made on average 1.8 years of growth as measured on the Qualitative Reading Inventory.” Christina Sorenson, Leander, TX “Students with severe reading difficulties were reading. The most wonderful blessings were watching them succeed for the first time and feel like true readers.” Marsha Allen, Santa Fe, NM “(WordFlight™) has helped with confidence, oral reading, fluency and decoding skills. My goal is that they feel more empowered to become lifelong readers, even if aspects of it are hard.” Jill Powell, Sioux Falls, SD CONTACT Contact customerservice@wordflight.com for help or suggestions, or visit https://www.wordflight.com/contact/ Privacy Policy: https://www.wordflight.com/privacy-policy/
