Commutative property 

True or False ?

The commutative property of multiplication tells us that when multiplying numbers, the order of multiplication does not matter.

True

Examples:

5x7=7x5=(35)

23x2=2x23=(46)

100

3.  6,588=6,590

200

Associative property 

True or False?

The associative property of multiplication tells us that the way in which factors are grouped in a multiplication equation does not change the answer.

True

Examples:

 8 + (2 + 3) = (8 + 2) + 3 = 13.

(6x5)x7= 6x(5x7)
(30)x7= 6x(35)
210=210

200

1. 71,146

200

Use the associative property to fill the missing values. 

1).  (×8)×82=82×(×47)

HINT . . . what ever numbers are on one side of the equation, must be on the other side as well.

1). (47×8)×82=82×(8×47)

200

3. 0.167+0.84=

4. 1.88+0.71=

3. 0.167+0.84=1.007

300

Distributive property 

The distributive property of multiplication tells us that 5 x (2 + 3)  is the same as 5 x 2 + 5 x 3.

True or False? 

True

Examples

4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.

7 × (20 - 3) = (7 × 20) - (7 × 3) = 140 - 21 = 119

1. 5×69= 

2. 10×52=

1. 5 × 69 =  (5 x 60) + (5 x 9) = 300 + 45 = 345    

2. 10 × 52 =  (10 x 50) + (10 x 2) = 500 + 20 = 520

Acute angles

400

Name this angle:

Right Angle

An angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.


400

6. 3×91= 

7. 9×65=

6. 3 × 91 =  (3 x 90) + (3 x 1) = 270 + 3 = 1273   

7. 9 × 65 =  (9 x 60) + (9 x 5) = 540 + 45 = 585  

400
