**1.****David said he could model the multiplication (+3) x (-7) using 3 red chips and 7 blue chips.**

**A) Do you agree with David? Explain.**

**B) What chips would you use to show (+3) x (-7)? Explain**

A) No, because you aren't removing, therefore you don't need any red chips.

B) I would use 21 blue chips. 7 chips in 3 different groups. I think this because (+3) x (-7) means make 3 groups of (-7).

__8.__Write each expression as repeated edition.A) (+7) x (+2) = 2+2+2+2+2+2+2

B) (+4) x (-9) = (-9)+(-9)+(-9)+(-9)

__12.__What mulitplication statement does each set of diagrams represent?**A)**

A) (-1) x (+7) = (-7)

**B)**

B) (-2) x (-5) = (+10)

__15.__An aircraft descends at 3m/s for 12s. Use multiplication of 2 integers to represent the situation. How far does the aircraft descend?

A) (+3) x (+12) The aircraft has descended 36m.
