Student Outcomes

  • Students understand the rules for adding integers:
    • Add integers with the same sign by adding the absolute values and using the common sign.
    • Add integers with opposite signs by subtracting the smaller absolute value from the larger absolute value and using the sign of the number with the larger absolute value.
  • Students justify the rules using arrows and a number line or by using the Integer Game and extend their findings to begin to include sums of rational numbers.
