Yes — "though" is a Fourth Grade sight word. Its "gh" is completely silent, and the "ough" combination makes a long "o" sound that isn't obvious from the spelling alone.
It was cold outside, though the sun was shining.
"Ough" is famous among English learners for making wildly different sounds depending on the word — compare "though" (long o), "through" (long oo), "tough" (short u), and "cough" (short o + f sound). Because a single spelling pattern can sound so many different ways, each "ough" word has to be learned individually as a sight word.
Show your child the "ough family" side by side — though, through, tough, cough — so they understand why memorization, not sounding out, is the right strategy for this whole group.
