Students can use information about their favorite basketball players, specifically free throws attempted vs free throws made and you could add field goals attempted vs made and 3 pt shots attempted vs made to determine the percentage of each. Students can them fill in the information about their favorite player on the information to the right of the card.

It will work best if you bring in basketball cards, or have the kids bring in basketball cards and then you use tape to blackout the percentages on the back of the cards.

This can be modified to work with other sport cards as well.
