### 8.2 Page 296 Questions 1, 3, 5 and 7

#### 1.) Darcy modeled (+7) x (+3) on a number line by drawing seven arrows. Ishnan modeled (+7) x (+3) on a number line by drawing only three arrows. Explain Ishnan's thinking.

**Darcy did 7 groups of 3 while Ishnan did 3 groups of 7. It still works because the product is the same and Ishnan just "switched" the two numbers.**

#### 3.) Without doing any calculations, Wei said that -19 and +27 have the same product as +19 and -27. How did she know?

#### 5.) What multiplication statement does each diagram represent?

**a.) 2 x (-6) = -12**

**2 groups of negative 6 equals negative 12**

**b.) 4 x 4 = 16**

**4 groups of 4 equals 16**

#### 7.) Determine each product.

a.) (+4) x (-7) =

**-28**

__4 groups of -7__

b.) (+2) x (+9) =

**18**

__2 groups of 9__

Great Job Kathleen! Your explanations were good and in detail but your pictures were a little too small. Overall, great job!
