First off, Rrhain, it's much better if they have to read their own Bible and run into things themselves.
The problem of reading it as Noah begat Shem several years after he was 500 years old is that you have to invalidate the accuracy of all of the other chronologies, which use the same wording.
Are our resident YECs willing to invalidate the accuracy biblical chronology to attempt to fix this error? What about other similar errors? For example, Abram is born in 1949 AC. In 2024, Abram leaves Haran after his father's death. However, his father doesn't die for another 65 years. Samson judges in 2929 AC, and dies in 2949. Eli then judges for 40 years - 2989. Because of Acts 13:19-20, Samuel takes over 450 years after the land is divided (2559 + 450 = 3009). There's a 20 year gap with no judge. Of course, there's a conflict with 1 Kings 6:1 as well, which states that from Exodus to the temple is 480 years. This gives only 30 years for the Exodus, Samuel, Saul, and David combined. If you try and reconcile temple construction, you end up with a 114 year gap (temple begins in Solomon's 4th year as king, 480 years after Israel leaves Egypt).
I could keep on going. The issue is, the dates don't reconcile.
