In the spirit of this time year, I have created a reinforcement activity that can be tailored for any target area.
Simply cut out the pieces, laminate, and put them face down in the middle of a table. Students answer a question, catered to their goal, and if they answer correctly, they draw a card. If they select a rocket, they get to keep it. if they select a firework, they have to return all cards to the middle. The student with the most rockets at the end of a given time period is the winner.
