Skip Count by 3 Card Game is a fun way to practice skip counting.
The player who gets rid of all their cards first wins.
Set up: copy on cardstock, laminate, cut up all of the cards, pass out all the cards, and put the yellow board in the center. A player that has a 3 can put their card down, then whoever has a 6 can put it down next, and so on... After they get to 30, they start back over at 3. The player who gets rid of all their cards first wins.
