6. Geometric Model for Distributive Property Two ways to find the area of the rectangle. 4 52 As a wholeAs two parts same

7. Find the area of the rectangle in terms of x, y and z in two different ways. x yz As a wholeAs two parts

8. Find the area of the rectangle in terms of x, y and z in two different ways. x yz As a wholeAs two parts same

9. This means that you can multiply 1 to any number... and it keeps its identity! The number stays the same! Let's look at the number 8. Anyway we try to multiply 1 to it, the 8 just keeps coming back as the answer. This means that you can add 0 to any number... and it keeps its identity! The number stays the same! Let's look at the number 5. Anyway we try to add 0 to it, the 5 just keeps coming back as the answer.
