A fourth grade teacher posted the following multiplication problem: 23x12. Sally says the answer is 276. Michael says the answer is 206. Who do you agree with and why? Give a reason for your choice. by Lisa Moore

Sally because 20x12=240 and 3x12=36 36+240=27

6368521619 — 2016-10-17 13:47:27 UTC

sally because 12x20=240 and 3x12=36+240=276

9572279742 — 2016-10-17 13:52:19 UTC

sally got it correct because 12x20=240 and 3x12=36 and then if you add 240+36 you get 276. (im not loking at anyones work)

2016-10-17 14:35:32 UTC

sally because (20x12=240)and3x12

2016-10-17 14:36:27 UTC

sally becuase 12x20=240 and 12x3=36 and 36+240=276

2016-10-17 14:37:14 UTC

I agree with slly because12 x20=240.12x3=36 and 240+36=276.Thats why sally is right

2016-10-17 14:40:14 UTC

sally because

2016-10-17 16:27:41 UTC

20x12=240 and3x12

Sally because you can break 23 into 20 and 3 and 20x12= 240 and 3x12=36 so if you add 240+36 you get 276

12515542 — 2016-10-17 19:05:13 UTC

sally is correct because 23 multiplyed by 10 equals 230 and 23 multiplyed by 2 equals 46 and 46 plus 230 equals 276

12498042 — 2016-10-17 19:08:50 UTC

Sally beacause 23 x 12 = 276 and not 206. Used the Chromebook Calculator for this.

8714732 — 2016-10-17 19:09:30 UTC

Without thinking that, it's because 276 > 230. 206 < 230.

sally is right because if you multiply 12 and 20 you will get 240 and then you multiply 3 and 12 and get 36 and 240+36=276

2016-10-18 13:46:00 UTC

that it why sally is right

Sally is correct because if you multiply 12 and 20 you get 240 then multiply 3 and 12 and get 36 240+36=276

2734572435 — 2016-10-18 13:48:27 UTC

sally because if you multiply (10x10)+(10x10)+(3x12) you would get 276

2016-10-18 13:49:57 UTC

Sally is correct because when you multiply 23 and 12 it equals to 276.

2016-10-18 13:56:10 UTC

Sally is right because 23 x 12 =276.I know this because I split 23 into 20 and 3.(20 x 12) +(3 x 12) =276.

9971651823 — 2016-10-18 13:57:21 UTC

sally is correct because when you multiply 20 and 12 you get 240 and when you multiply 3 and 12 you get 36 and 36 plus 240 is 276.

12521366 — 2016-10-18 13:58:14 UTC

sally is right because if you add 10 and 23

2016-10-18 14:01:37 UTC

Sally because 23 x12 =276 and she got 276 or 240+36=276 either way Sally is right.~Jaya

5985289265 — 2016-10-18 14:06:06 UTC

sally is right because if you multiply 12 and 23 it will pass 206 then it will be 27

2016-10-18 14:07:40 UTC

2016-10-18 14:08:01 UTC

Sally is correct because 23 multiplyed by 12 = 276 not 206 that is why Sally is correct.

Sally is correct because 20x12=240 and 3x12=36 so then I added 240 and 36 and got 24

sally is correct because (20x12)+(3x12)=276

SALLY

7344192764 — 2016-10-18 14:12:48 UTC

Sally because 23 multuplyed by 12= 276.

12608294 — 2016-10-18 14:19:04 UTC

(20x12)+(3x12)=276

sally because 12

2016-10-18 14:19:41 UTC

Sally is correct because 23 by 10=230 and 23 by 2=46.So 230+46=276

4243683387 — 2016-10-18 14:22:59 UTC

sally is correct because 23 times 10 is 230 and 23 times 2 is 46 so 230 plus 46 equals 276.

2016-10-18 15:42:02 UTC

sally is correct because 10+10+3=23 so if you split your rectangal into 3rds you will do 10x12=120 so 10x12=120 then 12x3=36 so 120+120=240+36=27

2016-10-18 15:52:57 UTC

sally because if you do 23 12 times it is 276

sally is correct because12 times 12 +12 times 11=276

2016-10-18 16:06:24 UTC

12592588 — 2016-10-18 16:14:04 UTC

Sally is correct because 23 x 10= 230 and 23 x 2=46 and 230 + 46= 276.
