# Order of Operations

### Bingo Order of Operations:

## What is the Order of Operations?

Order of Operations is usually considered with Please Excuse My Dear Aunt Sally (PEMDAS) for which the "P" stands for parenthesis, " E" for exponents, "M" for multiplication, "D" for division, "A" for addition and "S" for subtraction. In doing these operations we can solve mathematical expressions.

## BIngo Review:

Today as a quick review for the small quiz (today) and to add a little bit of fun into math, we are going to play Order of Operations bingo. I will be giving you a BINGO board with expressions on it and I will be calling out one answer at a time. Then you as students will have to solve each expression (before the game starts) to win Bingo. This is a good way to practice the Order of Operations in a fun and exciting math game.

## Some Bingo Expression Examples:

## Example One: First you do the inside parenthesis and then the exponents. So 6+4 = 10 and then you square it so the answer will be 100. | ## Example Two: First you do the parenthesis first and then multiply. So (3-2+9) is 10 x 6 =60. | ## Example Three: The equation says 4+(7-1x4)+3x2+(8-1). Since there are two sets of parenthesis we work left to right first. So we need to start with the first set of parenthesis and then go to the second set. So (7-1x4) = 24 and the second parenthesis (8-1)=7. So now the equation is 4+24+3x2+7, now we must multiply the 3x2 = 6. Now we add all the numbers together and get 4+24+6+7=41. |

## Example One:

First you do the inside parenthesis and then the exponents.

So 6+4 = 10 and then you square it so the answer will be 100.

## Example Three:

The equation says 4+(7-1x4)+3x2+(8-1). Since there are two sets of parenthesis we work left to right first. So we need to start with the first set of parenthesis and then go to the second set. So (7-1x4) = 24 and the second parenthesis (8-1)=7. So now the equation is 4+24+3x2+7, now we must multiply the 3x2 = 6. Now we add all the numbers together and get 4+24+6+7=41.

## Some of the Expressions on the BINGO card's will have multiple steps and others will not, be careful in your math and make sure to do the operations in order.

## Bingo Rules:

Your are to play individually, We will have three different opportunities for you to win. The winner will get two extra points on their mini quiz. Students will have to put a chip on the equation to the answer I call out, once you get five in a row, column, or diagonal you may call out Bingo and see if you really do have a BINGO. To check if you have a BINGO I will have you tell me what answers you put to what expressions if you are wrong we will assume and keep going until I find another winner. If you are right I will hand out new boards and we sill start again.
