It's the micro-decision every practice session poses a dozen times: the kindergartner misreads a word β do you correct, or let it ride? Both answers are right at different moments, and knowing which is which turns kindergarten reading books sessions from tense to smooth. The decision guide:

Let it ride whenβ¦
The error preserves the meaning. "Home" read as "house," "dad" as "daddy" β the child is comprehending; the substitution proves it. Interrupting meaning-safe errors buys nothing and costs flow. They're mid-sentence with momentum. Wait for the sentence's end; a reader in motion is building fluency, and fluency outranks any single word. They self-correct. The gold-standard behavior β a child who catches their own error is monitoring, the skill above all skills. Never interrupt a self-correction in progress, and quietly celebrate completed ones ("you fixed that yourself"). The session's emotional budget is spent. On the fragile nights, comprehension-safe errors ride free. The session's job is ending on a win.
Step in whenβ¦
The error breaks the meaning. "Big" for "dig" derails the sentence β pause at the period, then the light redirect: "check that one again β what sound does it start with?" The same word fails repeatedly. Three misses on the same word means it needs direct help: supply it ("that word is said"), move on, hunt it together later. Supplying beats grinding. The guess bypassed the print entirely. The picture-glance guess gets the standing reroute: "good thinking β now check the letters."
How to correct when you do
The mechanics matter as much as the timing: wait a beat first (give self-correction its chance), point rather than sigh, keep the voice conversational, and correct the word, never the child. The oral-reading guidance at Reading Rockets supports exactly this calibrated approach β meaningful errors addressed, momentum protected, and the reader's confidence treated as the session's primary asset.
The ratio to hold
Rough target: let two ride for every one you touch. A session that's mostly flow with occasional light repairs builds a reader; a session that's mostly repairs builds an avoider.
Not every stumble is a teaching moment. Most are just walking. πΆ
