🧭 Skill map, skill checks and summaries

The skill map, the weekly skill checks and the "What your child is learning" summaries use the Marble Skill Taxonomy (v1) · © Generative Spark, Inc. (Marble) · withmarble.com.

The database (skills, prerequisite links and links to standards) is licensed under the Open Database License (ODbL) 1.0, and Marble's text (skill names, descriptions, evidence, questions and summaries) under Creative Commons Attribution-ShareAlike 4.0. Source: github.com/withmarbleapp/os-taxonomy. OakCrest uses it unchanged, converted to JavaScript, in assets/marble/. Those files stay under the same licences; you may reuse them on the same terms. OakCrest's links from its lessons and apps to these skills are in assets/skill-tags.js.

The skills carry codes of the standards they come from:
