CommonLit Mini Units are ready-to-teach reading and writing units for grades 6–12 that take one to two weeks to complete. Each has 4–8 sequenced lessons built around authentic texts and two or three focus skills, and students finish with a polished piece of writing. They're built by CommonLit's curriculum team and included in every paid package.

Most Mini Units take one to two weeks. Explanatory Writing takes about 4–5 days, Narrative Writing about 6–7 days, and Argument Writing about 8–9 days. Reading Mini Units take about 7–8 days, or 4–5 days if the teacher stops after the Discussion Lesson and skips the essay sequence.

Mini Units are available for grades 6–12. Each grade has five Mini Units, 35 across the full set. Note: Three are available at launch for the 2027–2028 school year, and two more go live during the school year.

Library lessons are designed to stand alone, so each lesson's questions cover everything its text has to offer. Mini Unit questions are written as a set: they stay on the same focus skills from text to text, build in difficulty, and ask students to connect ideas across texts before they write. The library is a set of ingredients; a Mini Unit is the meal.

No. Mini Units are a supplemental resource. Mini Units lessons are written in the style of CommonLit 360 lessons, but they aren't part of 360 and don't replace 360 units. A Mini Unit goes deep on a limited set of skills, while a full-year curriculum covers the breadth of grade-level standards. Teachers who want more can explore CommonLit 360, our full-year ELA curriculum for grades 6–12.

Yes, with guardrails. In a Reading Mini Unit, teachers can stop after the Discussion Lesson, omit one of the three texts, or run the essay sequence with a small group. In a Writing Mini Unit, teachers can skip supportive lessons if students don't need the practice, or add extra prompts. A teacher guide shows which adaptations work well. Lessons are sequenced to build on each other, so they're meant to be taught in order, not used as standalone activities.

No. Mini Units are teacher-led, grade-level instruction for introductory and additional practice. They are not a Tier II or Tier III intervention program, and they are not a diagnostic or summative assessment. Every lesson includes scaffolds, such as focused During Reading Questions and companion decks, so students stay supported.

Mini Units are included in CommonLit Spark ($4,200 per school per year for one year), Core ($7,200), and Elevate ($12,800), with lower multi-year pricing available. There's no separate charge, and Mini Units aren't sold on their own.
