Watch closely during practice and you might spot it: your kindergartner hits an unknown word, glances at theΒ picture, and produces a plausible guess β "horse" for "pony," "house" for "home." It looks like resourcefulness. It's a habit worth redirecting early, and kindergarten reading books are where the redirect happens.

Why guessing feels like reading but isn't
Picture-and-context guessing produces right-enough answers in kindergarten books, where illustrations telegraph everything β so the habit gets rewarded daily. The bill arrives later: around second and third grade, pictures thin out, words get specific, and the guesser hits a wall the sounder-outer never meets. The reading-science material at Reading Rockets is direct on this: skilled reading runs on decoding the actual letters, and guessing strategies that bypass the print build a foundation that collapses under real text. The fix isn't punishing guesses β it's rerouting the first move.
The redirect: "check the letters"
The in-the-moment script, calm and consistent: when a guess arrives, don't say "wrong" β say "good thinking β now check the letters. What sound does it start with?" You're honoring the intelligence (the guess was smart) while installing the correct first move: eyes to print, sound it through, then let the picture confirm. Pictures demote from answer key to fact-checker β which is their proper job.
The book-side supports
Two shelf moves reinforce the redirect. Decodables for the practice slot: their whole design purpose is making guessing impossible β every word winnable by sounding out, no picture shortcuts available β which is exactly the environment where the letters-first habit sets. The finger anchor: during their reading, a light finger under the current word keeps the eyes on print instead of drifting art-ward at the first difficulty.
Keep the pictures glorious everywhere else
Important boundary: this is a practice-slot redirect only. In the read-aloud and the browsing basket, picture-reading stays celebrated β illustration literacy is a genuine skill, and the emotional information in the art is half the value of the bedtime shelf. Letters-first for decoding; pictures-first for everything else.
Smart guess, wrong first move. Reroute the eyes; keep the praise. π
