Overview
K12-KGraph is a curriculum-aligned knowledge graph built from official People's Education Press (PEP) K-12 textbooks. It focuses on curriculum cognition, namely the structured understanding of how school knowledge is organized, connected, and sequenced.

dyck-k128-seq_len_2048-1B
Procedurally generated k-shuffle Dyck bracket sequences (Hu et al. 2025, arXiv:2502.19249), as flat uint16 token-id .bin files. Token ids are 0-based: opening bracket type i is id i and its matching close is i + k, so ids span [0, 2k) and the vocabulary is 2k = 256.

US K-12 Schools Directory
A directory of 124,613 US K-12 schools covering all 50 states, DC, and US territories,
compiled from federal and state government sources. Each record carries directory
information (address, phone, website), enrollment and demographics, and, where a source
supplied it, a principal name and email.
This is a compilation of public government data. It is not a survey, and no field was
independently verified against the school itself.

K-12 Curriculum Tasks (generated)
2,489 generated instruction/input/output records covering five curriculum tasks:
assessment creation, learning objective generation, misconception detection, standard
explanation, and standards Q&A. Content is predominantly mathematics.
Important: the name is misleading
Despite the name, this dataset contains no school directory data. There are four

Ask a language model about a large suburban high school and it will answer. Ask it about
the K–8 school in a rural county of 4,000 people and it has nothing to say — because
nothing about that school was ever written down on the open web. Only about 12% of

里面有两个数据文件，completion.jsonl和distilled.jsonl。
其中，completion.jsonl是gemma2-27b-it生成的数据，因为gemma2-27b-it最后得到的结果可能提取不出\boxed{}里面的内容等因素，所以最后生成了约18.6k的数据。
而distilled.jsonl是基于上面的回答成功的问题，使用DeepSeek-R1-Distill-Qwen-32B生成的数据（其实不应该这样，之后有机会再从20000条里面直接生成）。
因为NuminaMath-CoT的cn_k12数据大多是一些综合应用题，一条数据中会有多个子问题，回答的时候也要分别回答。对问题回答的答案进行验证较难，尚未进行答案验证，需要下载下来之后再进行更精细化的处理。

Deprecated - use k12-science-standards-expanded instead.
This dataset is superseded: every instruction in this set also appears there, plus 1,123 more and nine additional metadata columns. Nothing here is unique to it.
