The US Bishops have released an extremely useful side-by-side comparison chart of the translation as it currently stands and the new translation that more closely mirrors the original Latin.
There are PDFs that you can print for your own use. Throw some burgers on, open a bottle of wine, invite some friends over and hand out the PDFs to discuss. Just throw in that these changes are only in the translation. The original Latin isn’t changing, only the inaccurate translations of some parts of the Mass are being retranslated in a more accurate fashion.
