Yes — "him" is a Dolch 1st Grade sight word. It follows regular phonics rules, but it's taught for instant, automatic recognition because it appears so often in early reading.
I gave the book to him.
"Him" is fully regular, but as a common pronoun it's taught for instant recognition early, the same as "he", "she", and "them" — words too frequent to sound out every time.
Group "him" with "his" — they look similar and both refer to the same person, which can help or confuse a beginner, so practice them side by side.
