a place value are alike and how they are different.
Observable: Students will read and write the California county populations in
expanded form, standard form, and word form.
Criteria: Given a list of county populations, students will identify which
numbers are in the millions period, thousands period, and ones period with
80% accuracy.
|
|
Prerequisite Background Skills/ Knowledge:
Students know California is broken up into many counties. These counties vary
in population.
Students know how to read and write numbers through the hundred thousands.
|
|

Procedure
|
|
|
|
|
|
|
|
Open:
As an attention getter, display the color coded California county map from
the previous lesson. Ask students to locate the most populated counties.
Write one of the least populated counties on the board.
For Example:
San Benito County
|
|
Input:
1st: Point out the standards we are working on (posted).
2nd: Ask students to read the population number for San Benito and give the
value of each digit:
San Benito County
53,234
Ask students to read the number and give the value of each digit:
(50,00; 3,000; 200; 30; 4)
3rd: Ask students to read the population number for a large county.
Los Angeles County
9,519,338
Ask students to read the number and give the value of each digit:
(9,000,000; 500,000; 10,000; 9,000; 300; 30; 8)
4th: Each group of three numbers is called a period or comma. These commas
separate one period from the next and help students read the number.
5th: Explain four ways to write the population for Los Angeles County.
9,519,338
1) Standard Form
9,519,338
2) Word Form
Nine Million, five hundred nineteen thousand, three hundred thirty three.
3) Short Word Form
9 million, 519 thousand, 338
4) Expanded Word Form
9,000,000 + 500,000 + 10,000 + 9,000 + 300 + 30 + 8
6th: Students will work in cooperative groups to write 5 county populations
in the above four different ways. High achieving students will work with
lower achieving students.
|
|
Guided Practice:
Model for students how to read and write a county population in four
different ways.
1) Standard Form
2) Word Form
3) Short Word Form
4) Expanded Word Form
Ask students how the millions period and the thousands period of a place
value are alike and how they are different. Discuss how both millions and thousands
places have places for hundreds, tens, and ones. Both have greater values as
you move from right to left. Each place value has a different value.
|
|
Independent Practice:
Students will work in cooperative groups to question one another on the value
of each digit of a county population number.
Students will work in cooperative groups to write 5 county populations in the
above four different ways. High achieving students will work with lower
achieving students.
High achieving students may write 3 different six-digit numbers using the
digits 1,2,3,4,5, and 6. Students will identify the value of 6 in each
number.
|
|
Close:
To close the lesson students will share ways they understand how to read and
write place value through the millions.
High achieving students may share their 3 different six-digit numbers with
the class.
Students will understand numbers can be written in different ways. Place
value can help students read and write numbers.

Assessment/
Reflection

|
|
Assessment:
Students will identify which California county population numbers are in the
millions period, thousands period, and ones period with 80% accuracy.
|
|
Reflection:
The objective of the lesson was achieved. Students were able to identify
which California county population numbers are in the millions period,
thousands period, and ones period with 80% accuracy. The lesson allowed
students to make a connection with a number in the millions place to a
tangible population of a county. Several students made an extension to the
lesson by memorizing a few of the California county populations. Students did
this on their own to understand how to read and write population numbers.
I did not anticipate the great disparity of understanding. Some of the
students finished the assignment in minutes while others struggled with a
basic understanding of place value. I allowed the high achieving students to
work with one another in finding other California counties to write out the
population numbers in various ways. I also allowed high achieving students to
work with low achieving students.
Ive tried to create a culture where students feel comfortable asking one
another for help. Students also made posters to explain how to read and write
their answers. This lesson was appropriate and on grade level because I
collected and used multiple sources of information to assess student
learning.
