I think the person with the hat was right because the other boy did 14 5 times and just skip counted by the 4's in the ones place but the boy with the hat skip counted by the 4's 5 times and that was 20 then he added the 5 ones and his answer was 25.

The guy in the jacket is right because 5 divided by 25 equals 5, because 5 groups of 5 is equal to 25. The other guy and woman were putting the one into the tens place instead of adding them together.

I think that the guy with out the hat was right BEACAUSE 5 gose in to 25 5 tims.when the guy with the hat solved the problum he put the 10s asthe 1s place wich was 5 4+4+4+4+4=20 so he said 2+5=25.But thats not right!!!

DEar Miss Russell ,I think the guy in the jacket is right because the other people did it right but they counted the tens place as one.

Dear Miss.Russell,

I think that the man is right. Beacause the other people couted the tens place as ones. So the man is right.

Dear miss russell,

the man in the suit was right. Because the other people couted the tens place as ones. So the man in the suit is correct.That is why.

Dear miss Russell,the guy with the hat and the lady where incorrect. The guywith the hat ccounted the ones with the ten's so he got the anwser of 25. - Anna

Billy was right because he said that 5 times 5 equals 25 and that is right (25 divided by 5 equals 5). Ma and Pa were wrong because they said that 14 times 5 is 25. Ma and Pa both had different ways to get to 25, but they were all wrong. Pa said 25 divided by 5 is 14 and Ma said 14 times 5 is 25.

Miss Russell,I think the man in the coat is right.Because 5 dose go in 25 5 times. The man and woman think 14 by 5 = 25.I disagree because 14 by 5 = 70.

-JOHNNA :D

The man in the jacket has the correct answer. Because the the man in the hat and his wife think that all of the numbers are in the ones place so they got the answer wrong because they thought 14X5= 25 when the correct answer is 70. The two people who were wrong thought the 10s place numbers were ones place numbers and came up the wrong answer of 14x5= 25.

There is a HUGE misconseption! because 14+14+14+14+14=70. But the guy with the hat counted the tens as ones. Then the guy with the suit was correct because 5+5+5+5+5=25. It was a misconseption because the guy with the hat counted the tens as ones.

I love this video. It is very thought provoking and the kids learn that there are many different ways to approach a problem. Thanks for the post. I have put it in my 3rd grade math word problem online binder (livebinders) for my kids to use when they are reviewing this summer. http://livebinders.com/play/play?id=1619
