Homework If you did not do the homework, you do not need to explain to me why. Just make sure that you do the missing assignment and turn it in the next day. Late homework needs to go in the “late work” tray at the front of the classroom.

Procedure for Correcting work Use a pen or marker to correct. Make a checkmark if it is incorrect. Write the number incorrect at the top. Trade papers with a partner. -3

Essential question: How is adding integers using the rules different than using a number line? Name date period Absolute value: Tells how far a number is from zero on the number line. Add integers

Rules Same sign Add the absolute values of the numbers. Keep the same sign. Different signs Subtract the absolute values. Take the sign of the number with the greater absolute value.

1) =

2) =

3) 11 + (-6) =

Practice 4) = 5) -4 + (-8) = 6) -1 + (-1) =

Practice 5) 7 + (-6) = 6) = 7) -4 + (2) = 8) 1 + (-1) =

Summary: One method for adding integers is using the integer rules. First, check the signs of both numbers. If both are the same sign, add their absolute values. Then, keep the sign. Otherwise, if the signs are different, subtract their absolute values. Take the sign of the larger absolute value number.

A positive number plus another positive number equals a ________ number, because __________________________. A negative number plus a negative number equals a ________ number, because ______. When we add a negative number with a positive number, we ____________________.
