The Integers They’re Multiplying!!! … And dividing?!

IWBAT multiply and divide integers. Today’s Objective IWBAT multiply and divide integers.

But first … A story! OOOHHH!!! I love stories!

MR. UGH

SAME GOOD DIFFERENT BAD UGH!!!

So what are the rules? So the rules for multiplying AND dividing integers are … 1.) If you have an EVEN number of negative signs, you get a POSITIVE answer.  Same good 2.) If you have an ODD number of negative signs, you get a NEGATIVE answer.  Different bad

TIC –Tac-Toe to win

Practice makes perfect! Let’s go!

Do you have same (good) or different (bad)? Example #1 Do you have same (good) or different (bad)? Multiply as normal

Do you have same (good) or different (bad)? Example #2 Do you have same (good) or different (bad)? Multiply as normal

Do you have same (good) or different (bad)? Example #3 Do you have same (good) or different (bad)? Divide as normal

Do you have same (good) or different (bad)? Example #4 Do you have same (good) or different (bad)? Divide as normal

Whiteboard practice. NOW!
