I am always looking for ways for my students to get more practice with their math facts. Games are the easiest way to do that - the students don't even realize they are working!
This is a version of the Kaboom game with a water balloon fight twist. Students choose a card, and get to keep it if they answer the math fact correctly. BUT... if they draw the dreaded splash card they have to put ALL of their cards back. the winner is the player with the most cards at the end of the game. Place the cards in a bucket or pail for an even more summer feel!
This game can be played with all of the cards or just selected cards for differentiation.
