1000 = thousand 100= hundred 10 = ten 1= one 0.1= tenth 0.01= hundredth 0.001= thousandth = ten-thousandth Decimal Places

3
Reading Decimals Step 1: Read the number before the decimal point

4
Reading Decimals Step 2. Read the decimal point as and

5
Reading Decimals Step 3: Read the number after the decimal place

6
Step 4: Follow the second number with the place value of the last digit Hint Reading Decimals

7
Hint.05 Draw and imaginary line underneath Reading Decimals

8
Hint.05 Reading Decimals Place a 1 under the decimal Place zeroes under each of the following numbers

9
is read as five hundredths Reading Decimals

TenthHundredth Decimal Models

12
Decimals that represent the same value Example: 0.6 is equivalent to = 0.60 Equivalent Decimals

13
Zeroes as last digit(s) of a number can be removed 0.6 = 0.60 Terminal Zeroes

14
Equivalent Decimals

15
Comparing Decimals Step 1: Underline the first number that is different in the numbers being compared

16
Step 2: Add terminal zeros so there are the same number of decimal places Comparing Decimals

17
Step 3: Remove the decimal point Comparing Decimals

18
Step 4: Order numbers depending on the directions given Comparing Decimals

19
Step 5: Replace decimal point and remove terminal zeroes Comparing Decimals

20
Which is greater: 0.6 or 0.58 ?

21
> 0.58

22
Which is greater: 0.6 or

23
Step 1: Underline decimal place we are rounding Rounding Decimals

24
Step 2: Circle the number to the right of the underlined decimal place Rounding Decimals

25
Step 3: If circled digit is greater than or equal to 5, then round the underlined number up (add one) Rounding Decimals

26
Step 4: If circled digit is less than or equal to 4, leave the underlined number the same Rounding Decimals

27
Try these: 1)Round 1.05 to the nearest tenth 2) Round to the nearest tenth Rounding Decimals

28
Answers: 1) 1.1 2) 0.12 Rounding Decimals
