**When you divide by ten 4 . 6 . 5 9 The answer gets smaller**

The decimal point moves to the left one place or the numbers move one place to the right 4 . 6 . 5 9 2 3 . 2 3

7
Divide by 10 30 10 43 10 567 10 7456 10 = 3 3.5 10 = 0.35 = 4.3 4.2 10 = 0.42 = 56.7 5.06 10 = 0.506 = 745.6 0.6 10 = 0.06

**After the decimal point**

Place Value & by 100 After the decimal point 100 10 1 . 1/10 1/100 1/1000 1/10000 5 2 3

10
**When you divide by 100 4 . 6 5 9 . The answer gets smaller**

The decimal point moves to the left two places or the numbers move two places to the right 4 . 6 5 9 2 3 . . 2 3

11
Divide by 100 30 100 43 100 567 100 7456 100 = 0.3 = 0.035 3.5 100 = 0.43 4.2 100 = 0.042 = 5.67 = 5.06 100 = 74.56 = 0.006 0.6 100

12
**When dividing by 10,100,1000- I know that the number gets smaller**

The place value of each digit is changing or the decimal point is moving Can I do this multiply by just looking at it? 10-1 =1/10 10-2 =1/(10 x 10) =1/100

13
**Powers of ten 100 = 102 10 = 101 1 = 100 1/10 = 10-1 1/100 = 10-2**

= 103 100 = 102 10 = 101 1 = 100 1/10 = 10-1 1/100 = 10-2 1/1000 = 10-3 (=10x10x10)(=10x10) (=10) (=1) (=0.1) (=0.01) (=0.001)
