In this bingo game students use a blank bingo board to fill in 25 numbers. The teacher will call out decimal problems that use all 4 operations. Instead of calling out the number the teacher will use Halloween symbols. For example the teacher may say " A pumpkin times a bat". The students will find the decimal value of each item and perform the operation. Once they have the answer they will mark it on their board. Two versions are provided, one with negative decimals and one without.
