Greg wants to put new carpet in his game room (which he only uses once he is done with his reading and math minutes for the night).
If his game room is 9 feet by 8 feet, Greg figures that he will need 63 square feet of new carpet.
Do you agree with him? Tell why or why not.
Prove it with your explanation.

No because 9X8=72 or 9+9+9+9+9+9+9+9=72
NO i think 63 is wrong because 9x8=72 so 63 is wrong.
i think it is 72 becus i did 9x8=72
No because 9 x 8 = 72 and he could just do cicles and stars and all the other stratigies we have used like magic fingers and repeated addition.
Greg is wrong because if you the magic fingerers trick it is 72 so Greg's anser is 72.
I desagree because 9 times 8=72 9 times 8 doesn't equal 63 so I disagree.
I don't agree beacauce when you find the area
you multuplie it so you would multuplie 8x9
and your anser would 72
No its the wrong a nswer because if you put your 8th finger down you get 72 not 63.
7x8=72
Greg is wrong. I multiplied 9 x 8 and got 72. So he needs 72 squares of carpet.
i think yo ned to moltiply 8x9 so 8x9=72 becos 9+9+9+9+9+9+9+9=72
the anser is 72
Wrong because 8 + 8 + 8+ 8 + 8 + 8 + 8 + 8 + 8 = 72 so that would be the answer.
No. 9x8=72.
No Greg. You will need 72 feet because I did this. I added 8 * 9 and it got me 72.
63 is not the anser.Becaues I aded 8 9 times and I got 72.

wrong becuse there are 8 rows and 9 sqauers equas 72
he is rong becaus if you do 9 time 8 = 72 so he is rong
no because i figured out that i multiply so i tried doing an eqausion like this 9x8 and i knew that problem 72 and that's how i know
