Curriculum
A full curriculum, authored to survive with no signal.
Untether does not stream. Every subject ships as a self-contained content pack — lessons, media, assessments, and an offline answer key — that runs entirely on-device and reconciles progress whenever a network appears.
Foundational Literacy
Phonics-through-fluency reading, structured writing, and oral-language packs in 14 languages, with printable fallbacks for classrooms without screens.
Numeracy & Math
Number sense to pre-calculus, each strand gated by a mastery check that runs offline and stores the result to the learner record.
Science & Practical
Inquiry units built around materials a rural classroom actually has, plus simulation packs for experiments that can't be run on site.
Vocational Tracks
Agriculture, health, solar, and device-repair modules co-designed with regional ministries and NGO partners.
How a pack is structured
Every pack, the same skeleton
Authoring is constrained on purpose: a fixed structure is what lets one field device, one printout, and one sync server all speak the same format.
Strand A — Lesson Sequence
on-device- Ordered lessons with embedded media, sized for low-power displays.
- Each lesson declares its prerequisites, so a device can hide what a learner isn't ready for.
- Printable one-page fallback generated from the same source.
Objective: a learner with a dead battery and a printout loses features, never the lesson.
Strand B — Practice & Mastery Gates
offline scoring- Item banks with offline auto-scoring and a per-item error taxonomy.
- Mastery gates that must be cleared before the next strand unlocks.
- Results written to the local learner record and queued for sync.
Objective: assessment does not depend on a marker, a server, or a signal.
Strand C — Teacher Companion
print + device- Facilitation notes for teachers who may be a grade or two ahead of the material.
- Grouping suggestions for multi-level, single-room classrooms.
- A weekly retrieval schedule so earlier strands don't decay.
