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

4
**Read the decimal point as “and”**

Reading Decimals Step 2. Read the decimal point as “and”

5
**Read the number after the decimal place**

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

6
**Follow the second number with the place value of the last digit Hint**

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

7
**Draw and imaginary line underneath**

Reading Decimals Hint .05 Draw and imaginary line underneath

8
**Reading Decimals Hint .05 Place a 1 under the decimal**

Place zeroes under each of the following numbers . 05 100

9
Reading Decimals . 05 100 is read as five hundredths

Decimal Models Tenth Hundredth

12
**Equivalent Decimals Decimals that represent the same value Example:**

0.6 is equivalent to 0.60 0.6 = 0.60

13
**Terminal Zeroes Zeroes as last digit(s) of a number can be removed**

0.6 = 0.60

14
Equivalent Decimals 0.6 0.60

15
**Comparing Decimals Step 1:**

Underline the first number that is different in the numbers being compared

16
**Add terminal zeros so there are the same number of decimal places**

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

17
Comparing Decimals Step 3: Remove the decimal point

18
**Order numbers depending on the directions given**

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

19
**Replace decimal point and remove terminal zeroes**

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

20
Which is greater: 0.6 or 0.58 ?

21
0.60 0.58 0.6 > 0.58

22
Which is greater: 0.6 or 0.58 0.6 0.58

23
**Underline decimal place we are rounding**

Rounding Decimals Step 1: Underline decimal place we are rounding

24
**Circle the number to the right of the underlined decimal place**

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

25
**Rounding Decimals Step 3:**

If circled digit is greater than or equal to 5, then round the underlined number up (add one)

26
**Rounding Decimals Step 4:**

If circled digit is less than or equal to 4, leave the underlined number the same
