Stretch them up

by Ed Young
Picture book · ages 4–8 · grades K–3 · 620L

Complementing on algorithmic thinking

by Hannah Fry
Nonfiction · 1050L
Accessible and genuinely important — Fry makes algorithmic bias and ethics concrete enough for a sharp middle-grader without talking down, though it reads as upper-middle-grade to early YA.

by Douglas Hofstadter
Nonfiction
Brilliant and strange, but it's a book for philosophically curious teenagers who want to think about minds, music, and meaning — not a 5–9 year-old touchstone; flag it now for the 14+ reader who will revisit it.

by Brian Christian & Tom Griffiths
Nonfiction · 1050L
Dense, clever, and genuinely thought-shifting for a mathematically confident early teen, but requires sustained attention and comfort with abstraction—not a fun read, a workout.
We'd skip — for now

by Roald Dahl
A step up — ages 8–12 · grades 3–7
Skip it if your child needs a warm, affirming read; the ending is deliberately cynical and may feel unsettling to younger or sensitive readers.
