Twenty-one different sport cards plus 2 key cards. Forty-four cards in total. I purchased a beautiful set of painted sports equipment cards to go with these sports cards. I put Casey at the Bat out for them to read and listen to. We also introduce Flags via who has won the World Cup in soccer/football (I'm from Scotland and now live in the US.) These cards are great for the children, because they know all the sports and can use them straight away with each other. This makes it a lot of fun. They can often be caught using these with the Moveable Alphabet too, just like the Dinosaur Cards.
