"Pom poms and megaphones" to cheer on the team for the year = cheese puffs chips and Bugles chips
Slam dunk slurpies (frozen fruit drinks)
Take String Twizzlers (the kind you can pull apart!) Give each kid a paper plate or towel to work on. Have the kids shape the Twizzler strips into a Basketball Net (laying it flat, of course... not 3D) OR you could make them to take and have the kids use Sour Straws to write their name across the net.
"Alley Oop Brownies!"
Brownies baked in small muffin tins... press down in the center about 1/2 way through baking to make a cup (basket!)Fill with a round candy (or even pudding)
Hope these are helpful. Have fun!
