Listen up kids and learn from mom. Gwyneth Paltrow brought her kids Apple and Moses to the 2015 Grammys at the Staples Center in L.A., on Sunday, Feb. 8, where they got to see their parents perform and present at the annual awards show.

Like most inquisitive young minds, the kids had questions about what was happening during the star-studded event. A source tells Us Weekly that the actress, 42, attempted to school her daughter, 10, and son, 8, about the differences between types of recordings.

"It was really funny," the insider tells Us. "She was backstage with them and was trying to explain the difference between a 'record' and an 'album.' Then she had to start over and try to explain what a record was [like a vinyl record]."

Her anecdotes, however, were rather unsuccessful. "I think the kids were super confused!" the source tells Us of the siblings, who have grown up without records, cassettes, and, for the most part, even CDs. (Meanwhile, in Grammy parlance — which still confuses grown-ups, too — the Album of the Year awards the artists and producers behind a full compilation of songs, while Record of the Year goes to producers of a single track. Another often-confused category, Song of the Year, awards a single and its artist.)

Both Paltrow and her estranged husband Martin, 37, played roles in Sunday's awards show: The Coldplay rocker performed onstage with Album of the Year winner Beck, while Paltrow (clad in a brilliant red sequin Stella McCartney dress) introduced BFF Beyonce before she sang "Take My Hand, Precious Lord."

Apple and Paltrow patiently stayed through the end of the Grammys to watch Bey's performance, and snuck out together after it had ended. Meanwhile, her father Martin got to rock out backstage with another famous celebrity tyke: Blue Ivy Carter.

Morning Phase winner Beck told Us at the Universal Music Group party that he and Martin "got to jam on some Hank Williams" with Jay Z and Beyonce's one and only daughter. "She's good on guitar!" Beck raved.
