Have some fun on Halloween and still practice comparing rational numbers (positive/ negative numbers, decimals, and fractions) and absolute value
Pumpkin attack is a game played similarly to battleship
Students pair up (one getting board A, one getting board B)
The questions on Board A have answers on the bottom of board B (and vice-versa). Students take turns solving a problem and telling their partner an answer. If the answer is on the pumpkin, its a hit! If the answer is around the pumpkin, its a miss! The first person to get all the "hits" is the winner.
