Triangle
By Mac Barnett
The Story
A shape sets off to play a sneaky trick on his friend Square, but the prank sets off a chain of trouble that tests who's really outsmarting whom.
Why It's Special
For the kid who loves a good prank almost as much as getting caught pulling one, Triangle turns a simple trick into a quiet game of who-did-what-to-whom.
- Big idea: Mischief has a way of circling back — and friendship survives it anyway.
- Vibes: Deadpan, minimal, sly — humor that lands in the silences between the words.
Perfect For Kids Who
- enjoy sneaky, wry humor
- like to guess what happens next
- are working on understanding cause and effect
- respond well to spare, moody artwork with big visual payoffs
