There are several bloggers in the #MTBoS (Math Twitter Blogosphere) that have written about Slow Reveal Graphs (sometimes called Numberless Graphs or Notice and Wonder Graphs).
Chris Hunter @ChrisHunter36

Chris describes using the graphs during professional learning with teachers, including making content area connections. He also introduces the beautiful New York Times feature “What’s Going On In This Graph?”
Jenna Laib @jennalaib

Jenna offers a vignette describing the use of a slow reveal graph to launch 4th grade work around colonialism and slavery in the Caribbean.
Chase Orton @mathgeek76
(Grade 2) (Grade 1)
