Yes — "look" is one of the first Pre-K sight words, appearing constantly in early readers to direct a child's attention ("look here", "look at this").
Look at the rainbow in the sky!
"Look" is spelled fairly regularly (the double "o" reliably makes the short "oo" sound here, as in "book"), but it's grouped with the earliest sight words simply because of how often it appears in beginning picture books — usually paired with an illustration the child is meant to look at.
Since "look" so often appears with a picture in early books, use it as a natural cue — say "look!" and point, reinforcing the word's meaning through action.
