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.

  • math 3rd grade -

    4x7= 28
    8x7= 56

    28 x2 = 56

    Tell ur 3rd grader that double of 4x7 (28) will equal to 8x7 (56)

    hope this helps :)

  • math 3rd grade -

    Well see 4x7 doubled is well 28+28=56 so 4x7 doubled is equal to 8x7 hope this helps

  • math 3rd grade -

    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)
