Lance wants to find the total length of 3 boards. He uses the expression 3 1/2 + (2+ 4 1/2). How can Lance rewrite the expression using both the Associative and Commutative Properties of Addition?

  1. Steve

    3 1/2 + (2+ 4 1/2)
    3 1/2 + 4 1/2 + 2
    3 + 1/2 + 2 + 4 + 1/2
    3+2+4 + 1/2 + 1/2
    9 + 1
    10

    or, you can rearrange the numbers in other ways.
