  • Darkened the hint-text very slightly (to make it just a bit more readable while minimally distracting the learner away from the question at hand)

Current Development Focus

Grokkoli is focused on core K-5 math (as defined by US Common Core), as this is where the majority of learning-gaps tend to go undetected.

Our main objective is to fine-tune Grokkoli's analysis and diagnosis of learning gaps.

As such, Grokkoli does not yet support:

  • Geometry questions
  • Specific units of measure (meters, grams, seconds, etc)
