Yes — "was" is a Dolch Primer sight word, typically taught in Kindergarten. The "a" is pronounced like a short "u" sound, not the short "a" you'd expect, so it must be learned by sight rather than sounded out.
It was a sunny day at the park.
"Was" is the past tense of "is" and appears constantly in everyday sentences, but its vowel sound ("wuz") doesn't match its spelling. A child sounding it out phonetically would likely say "wass" with a short "a" — which is wrong. This mismatch is exactly why "was" belongs on the sight word list.
Pair "was" with its opposite-tense partner "is" so children see how the word changes for past events — "is" becomes "was" the same way "are" becomes "were".
