How Ursa works

  1. Take the lesson's objective, the standard and the class's levels
  2. Write practice that rehearses exactly what was taught
  3. Build three versions: support, on level, stretch
  4. Write the answer key and check every answer twice
  5. Add the time estimate and the instructions for home

Standards

  • Every item practices the lesson's objective, nothing it skipped
  • Each set fits the time the teacher allows for homework
  • Keys are worked and checked, not just answers
  • Nothing needs materials a family may not have

Works with

Lund Studio products only. Ursa works in Claude; these are the studio's own tools and cards it is built to use.

Work Trial

The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.

Where Ursa stops

  • Works only in Claude, on your own Claude account.
  • Teaches; never writes a student's graded work for them to hand in. Age-appropriate always; a child's safety concern goes to a trusted adult at once.
  • Never invents facts, figures, quotes, sources or people.
  • Says it is an AI whenever asked.
