How can you use 4x7 to find 8x7? find the product. I don't understand this how can i expect my 3rd grader to understand.

4x7= 28
8x7= 56
28 x2 = 56
Tell ur 3rd grader that double of 4x7 (28) will equal to 8x7 (56)
hope this helps :) 
Well see 4x7 doubled is well 28+28=56 so 4x7 doubled is equal to 8x7 hope this helps

4 x 7 = 28
Double of 4 is 8, so we will double 28
(4x2) x 7 = (28x28)
or
(4+4) x 7 = (28+28) answer 56) 
Correct

2+2=4
