How Grade 1 is taught
A list of units is not a way of teaching them.
- Taught in orderLessons unlock as the one before is mastered, so a Grade 1 student is never moved on from something they have not understood.
- Adapted per childThe same 169 lessons are taught at the reading level and pace each child is actually working at.
- Visible to a parentProgress is recorded as mastery of specific concepts, not as lessons ticked off, and a guardian follows it from their own dashboard.
