How these briefings are leveled, what they're informed by, and what they are not.
Every story targets a Flesch-Kincaid grade level of 2.0–2.5 (roughly 450–600L on the Lexile scale): sentences average 8–12 words, vocabulary is mostly 1–2 syllables, one idea per sentence, no passive voice. One new/harder word is introduced per briefing and explicitly defined.
We borrow a core idea from Newsela's leveled-news model: quiz questions should match the reading level of the article they're about, not run harder than the text itself. A 2nd-grade story gets 2nd-grade questions.
This isn't a certified curriculum and hasn't been reviewed by a reading specialist — it's a parent project, built with AI, informed by the reading standards most U.S. schools (including California's) teach from: the Common Core Reading: Informational Text standards and Writing standards for grades 1–2.
| Multiple choice — main idea | RI.2.2 — identify the main topic/focus of a text |
| Multiple choice — key details | RI.1.1 / RI.2.1 — retell or answer who/what/where/when/why/how |
| Multiple choice — sequence/connections | RI.1.3 / RI.2.3 — describe connections between events, ideas, or steps |
| Multiple choice — vocabulary | RI.1.4 / RI.2.4 — determine the meaning of words in context |
| Open-ended, personal connection | W.1.1 / W.2.1 — opinion writing with a supporting reason |
| Open-ended, inference/why-how | W.1.2 / W.2.2, W.1.8 / W.2.8 — informative writing; recall info from a provided source to answer a question |
Sentence starters on every written response are a deliberate scaffold, not a standard — at this age, writing is effortful and a blank page is a bigger barrier than the thinking itself.
Each briefing links its sources at the bottom of the page — so you can check the facts yourself, and so you can tell us if you'd rather we lean on some outlets (National Geographic, Smithsonian, museum and university sites) over others. This is new as of late September 2026 and being rolled out gradually; older briefings may not have it yet.
