Where 100 Easy Lessons is strong

A one-time purchase
The $29.99 US list-price paperback keeps the cost low without a recurring curriculum subscription.
A printed script you can keep
The book puts 100 color-coded lessons in one volume for parents who prefer teaching from paper.
Free help alongside the book
The co-author provides sound, blending, and lesson-demonstration videos without adding a subscription.

Where Once is strong

Hear and see the model while you teach
Built-in audio and video demonstrations let you check a sound, blend, or exercise inside the lesson, rather than look for a separate training resource.
A short, varied daily routine
15-minute sessions combine short tasks such as sound review, blending, word reading, stories, and writing. The sequence advances at your child's pace.
Books your child can keep and reread
Starting at Lesson 30, lesson-aligned physical decodable storybooks build a library your child can read to grandparents, siblings, or you at bedtime.
A coach for your teaching questions
A dedicated instructional coach helps when you are unsure how to teach an exercise or respond to your child.
A story worth coming back to
Once connects its 200 lessons into one cohesive narrative with recurring characters. The connected story gives children a reason to read beyond completing an exercise. They practice new skills while following familiar characters and finding out what happens next.
Evidence at school scale
Once's in-school program has five ESSA Tier 3 studies and one Tier 2 study. Findings include a 0.46 effect size and i-Ready growth from the 38th to 67th percentile, with results across schools and districts. See the research.

The evidence

Evidence from Once's school program

LXD Research's 2024–25 ESSA Tier II study found a 0.46 standard-deviation effect for kindergarten students who completed 80 or more Once sessions, compared with matched peers. This was a quasi-experimental study of the in-school model, not a study of Once at Home or a head-to-head test against 100 Easy Lessons.
