Skill Paths

These paths currently cover 337 selected skills from Pre-K through Grade 12, with two five-question worksheet versions per skill. They do not cover the entire curriculum. Helpful foundations are optional, not locked prerequisites. A blank history means no evidence here, not a weakness. Pre-K activities welcome adult help with reading, pointing and recording answers.

A starting check is a small sample, not a validated diagnostic or a subject grade. Practice feedback checks answers to these questions, not overall mastery. Consistent recent practice means at least four correct out of five, without declared help, on two different days and both worksheet versions. Review intervals grow from 1 to 3, 7, 14 and 30 days after successful practice days. Evidence older than 90 days is marked for a fresh look.

Suggestions use the latest 20 saved rounds for each skill and the current question version. Repeat rounds on the same day do not advance the review interval. Help and active time are browser-reported. Printable worksheet results, video viewing and related games do not establish independently checked skill mastery here. All existing subject grades remain unchanged.
