Yes — "began" is a Third Grade sight word, the irregular past tense of "begin". Since it doesn't simply add "-ed" like most past-tense verbs, it must be learned as its own word.
The movie began right on time.
Unlike regular verbs that form the past tense by adding "-ed" (like "played" or "asked"), "begin" changes its inner vowel entirely to become "began" — a pattern called an irregular verb. Because there's no consistent rule to apply, each irregular past-tense form, including "began", has to be learned individually.
Practice "begin" and "began" side by side so your child sees the vowel change directly, rather than trying to apply a regular "-ed" rule that doesn't exist here.
