After saying the first card, teach students "drop, plop, scooch, rest."
First, pick up card #1 and drop it above card #2 on the rug. Second, pick up the whole stack and plop it on top of card #1. Third, scooch the pile back in place where it was before, then rest (one beat of silence) before beginning the new card.
The first couple of times you demonstrate "drop, plop, scooch, rest," say the words. After that, do it together silently so students don't hear this repeatedly, but hear and focus more on the rhythms you are all reading on the cards.
