| Input | What to estimate | Example |
|---|---|---|
| Weekly lesson drafts | Number of lessons planned each week | 5 |
| Manual planning time | Average minutes per lesson before AI support | 45 |
| AI-assisted planning time | Average minutes per reviewed AI draft | 20 |
| Differentiation time | Minutes saved by generating support, on-level, and extension versions together | 10 |
| Export and formatting time | Minutes saved by exporting reusable materials instead of reformatting from scratch | 5 |
Calculator Inputs
Simple Formula
Weekly time saved = lessons per week x (manual planning minutes - reviewed AI planning minutes + differentiation minutes saved + export minutes saved)
Example: 5 x (45 - 20 + 10 + 5) = 200 minutes saved per week, before accounting for reuse across future classes.
Use Realistic Assumptions
Count Review Time
- Include teacher review and edits.
- Include standards or curriculum checks.
- Include time to adapt for real students.
Count Reuse
- Reusable lesson structures compound over time.
- Exportable materials reduce future formatting.
- Differentiated versions can support multiple groups.
The biggest gains usually come from repeatable workflows: draft in the lesson plan generator, adapt for learners, then export and reuse materials from the same planning sequence.
