II. Draw and identify pictures of decimals
(down to tenths, hundredths, and
thousandths). (SOL 4.4a)
= 1 whole or 100
100
= 0.06 or 6
100
= 0.63 or 63
100
= .2 or 2

III. Count by fractions. (SOL 4.2a-b)
Example:
1 , 2, 3, 4, 5, 6, 7, 8, 9
4 4 4 4 4 4 4 4 4

(4/4 = 1 whole) (8/4 = 2 wholes)
This is the way we see the fractions on a
ruler.

8, 4, 8, 2, 8, 4, 8
IV. Understand where fractions fall on a
number line. Students should understand
what is half, more than half, and less half.
(SOL 4.2 a-b, 4.3)

Some examples include:
half (2/4, 3/6, 4/8, . . . . )
-------------------------------------------

more than half (3/5, 6/8, 9/12 . . . )
Ask your child questions such as:
less than half (1/4, 2/5, 5/12 . . .)
Where would ¼ fall on the number line?
Where would 3/5 fall on the number line?
V. Know specific decimal/fraction
equivalents. (Think about money!)
(SOL 4.2c)
VI. Know equivalent decimals.
(SOL 4.4a, 4.4c)
VII. Round decimals to the nearest whole,
tenth, and hundredth. (SOL 4.4b)
Where would 1 ¾ fall on the number line?
Specifically:
1 = .5 or .50
2
1 = .25
4
1 = .2 or .20
5
1 = .1 or .10
10
.2 = .20
3.4 = 3.400
3.456 rounded to the nearest:
whole is 3
tenth is 3.5
hundredth is 3.46
VIII. Identify the place value of decimals
in the tenths, hundredths, and thousandths.
(SOL 4.4a)
IX. Read the word name of a fraction and
decimal. (SOL 4.2a, 4.2c, 4.4a)

Notice the “th” at the end.
Say “and” in place of the
decimal.
