Place Value and dividing by 10, 100, etc
thousands After the decimal point 100 10 1 . 1/10 1/100 10 1/10 1/100 100 ten tenth hundredth hundred

Place Value &  by 10 millions thousands 100 10 1 3 4 7, 8 3 4

Place Value &  by 10 millions thousands 100 10 1 2 3, 4 5 8 9, 2, 2, 8, ,

After the decimal point
Place Value &  by 10 thousands After the decimal point 100 10 1 . 1/10 1/100 5 2 3 0 . 5

After the decimal point
Place Value &  by 10 thousands After the decimal point 100 10 1 . 1/10 1/100 8 2 3 8 . 2

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

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

Place Value &  by 100 2, 3 4 5 8 9 0, 1 2 0 2 3 4, 5 8 9, 2, millions
thousands 100 10 1 2 3 4, 5 8 9, 2, 2, ,

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

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

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

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

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)
