Place Value Review
Students should review the below information and be familiar with how to write
numbers in various ways, compare numbers, order numbers and be able to explain
their process in order to reach mastery. They may use the PEACE flow map model
to help explain their work. Samples of this are listed below.
Standard form: 76,356
Expanded form: 70,000 + 6,000, + 300 + 50 + 6
Word form: seventy six thousand, three hundred fifty six

two
Write the following numbers in expanded form:
a. Nine thousand, six hundred and twenty nine
b. 87,352

*** Students should be able to explain how and why they

P
I am going to
write a number in
expanded form.
E
I will use my place
value chart to find
the value of each
number.
A
I filled in the rest of the
columns with zeros to
show the value of each
number.
A
I drew a place value chart
and placed the numbers
from my numeral in the
correct spots on the chart.
C
I know I am right because I checked
my work by writing it a second way
and the numbers lined up into the
original number I was expanding.
Value – the amount that a number is worth. For example, in the
number 4,578, the 4 is worth 4,000.
Place Value – The place on the place value chart that the number
is in. Ones, tens, hundreds, thousands, ten thousands or hundred
thousands.
***Students should also be able to write numbers in order from
least to greatest and greatest to least and compare two
numbers with these symbols. <, >, =. They should also be able
to explain how and why they ordered the numbers as they did.
P
E
I am going to compare
two numbers.
A
Once I have found two digits that
are different, I decide which one is
bigger and write that number down.
I continue this process until I have
ordered the numbers correctly.
A
I will use my knowledge of
the place value chart to
decide which number is
bigger.
I start by comparing the first
digits in both numbers. If they
are the same, I compare the
next two digits.
C
I know I am right because I checked my work by
writing it a second way and comparing each place
value.
