The model can be used  to find the result of 54x78 by deconpoes 54 and 78 then multply the deconpoes numbers. Then to find the result use the area model to get 4,212.I can prove the answer is 4,212 because i used a area model/box methed.

My group and I used the area model to solve 78x54, what we did was, we put all the number around the box, like 70,8,50,4 we then multiplied 5x7 and got 35 we also added the two zero's from 50 and 70 so we got 3500, we also multiplied 5x8 and got 40 and also added a zero from 50 so we had 400, we then multiplied 4x7 and got 28 and added a zero so we had 280, then we multiplied 4x8 and got 32, so after we did all that we added all the numbers together, 3500 + 400 + 280 + 32 and got 4,212.

The strategy I used to solve this problem is the box method.

# data[].attributes.body
I can prove my answer is 4,212 because 0+0+0+2=2 and 0+3+8+0=11 and you add 10 to the hundreds and then you have one in the tens and 1+5+4+2=12 and you add 10 to the thousands and you get 2 in the hundreds and 1+3=4 and all of that is 4,212 and that was my prof that it is 4,212.

The strategy I used to solve this problem is the area model. First I made the box and decomposed 78 into 70 an 8. Then I decomposed 54 into 50 and 4. I put the numbers on the top 70 and 8 I put it in the top. On the side I put 50 an 8. I multiplied 50 and 70 and I got 3500. After that I multiplied 50 and 8, I got 400. Then I multiplied 4 and 70 and got 280, after I multiplied 4 and 8 and got 32. Then I added all the products and got 4,212. That means 78 x 58 = 4,212. :)

l Know my answer is reasonable because the answer

# data[].attributes.body
I started by doing a area model. Then after I added them up to get 4,212.1st I did was 50 x 70 = 3500. Then I did 50 x 8 =400. Then I would do 70 x 4 = 280.Then last I would do 4 x 8 = 32 .

# data[].attributes.body
I did the box method to answer 54x78

I did 50x70=3500

and then 50x8=400

and then 4 x 70=280

and then 4x8=32

and then i added 3500,400,280 and 32 together and got 4212

the keywords are model and explain and quantiteies are 5 ans 78 and 7,8,5,4. We are findding thet answer to 54x78

# data[].attributes.body
finding out what 54x78

# data[].attributes.body
I think the box method
then 54x78 then finding out what 54x78=

# data[].attributes.body
1.i think the story is about finding what 54 x 78 equals
2.i think the quantities are 54 x 78
3.solve 54 x 78 in the box method.

# data[].attributes.body
The quantities and units are 54,8.70 explanation, model, you could do 50, 70,4, and 8

# data[].attributes.headline
Explain the model the result 5x 78 find the result of 54x 78 

# data[].attributes.subject
Explain the model the result 5x 78 find the result of 54x 78 

# data[].attributes.body
The most important parts I would underline are 50,70,4, find the results 8, 54, 78, model, and explanation. Another thing would be how the model could be used to solve 54 x 78.
