Grouping Property of Addition

The "Grouping Property of Addition" simply means that you can "group" numbers with parentheses and this also does not change the answer.  This concept is not true for division. Therefore, upon hearing the word "group" your student should look for parentheses that group different numbers on either side of the equal sign. Therefore, "B" would be the correct answer here.

  C. 2 + 8 = 8 + 2
