She headed back upstairs again and we were left to work on some addition and subtraction problems before lunch. I thanked her for her work in searching out the truth for us. Opening up to section 208, she started to read the definition that multiplication and division are treated equally and are solved from left to right as are addition and subtraction. Link returned, a book in her hand, to deliver her “ruling.” Everyone waited for her to open up her “Math on Call” book. Off she headed, and we tried to settle down to do some place value work.Īfter about five minutes, Mrs. Link announced to the class that was going to consult with some other math experts and see if she could clarify the confusion. She listened to the student who talked about her dad’s research and nodded that she agreed with that theory. She shortly came downstairs and respectfully listened to the “26” camp and the “14” camp. Quickly, I decided to phone a friend, in this case our math specialist Mrs. But, you taught us PEMDAS, addition is before subtraction. More mass confusion rang throughout the room. Another girl raised her hand and said she had a similar question on this problem the night before and her father had looked it up on the internet, where he said that addition and subtraction are treated equally and one should do the operation from left to right. As soon as that student finished, over half the class raised their hands, saying “no, you do addition before subtraction, remember PEMDAS. “You divide 8 by 2, which is 4, then you subtract 4 from 24 which is 20 and add 6 which is 26. I asked for volunteers to explain how someone may have arrived at 26 for an answer. On this rainy Thursday, I started our math class by putting that problem on the ActivBoard and put down 26 and 14 as a possible answer. So, I decided not to make that answer right or wrong and put it in front of the class for discussion. Since I have been getting ready for an observation, I was recently reading over “22 Verbal Events in a Class that Lets Kids Get Smart.” One of the suggestions was to for students to take initiative to explain another student’s thinking, including how they might have made an error. Since, I am always subject to making my own errors, I wasn’t sure. Clearly, there was a difference of opinion on the correct answer. But the next five students had 14 for an answer. Sitting down to correct the work on Wednesday evening, the first student had 26 for an answer. I calculated that the answer should be 26. I always do out the answers before starting to correct the problems. So, several nights ago, this was one of the problems on the homework: Some problems that we have encountered have been relatively straight-forward, while others have been on the somewhat tricky side. It’s been a few years (okay, more than a few years) since I have last worked with this concept, but I remember the mnemonic as standing for “Parentheses, Exponents, Multiplication, Division, Addition, Subtraction”, aka “Order of Operations.” Not only have we learned this, but we have also learned about brackets and braces as well.
