Background For Teachers: Our place value system is based on a pattern of tens. Each place
value increases ten times the value of the place to its right. We use
the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to write any whole number.
The symbols are called digits. Digits have different values depending
on their position in the number. You can count items using whole
numbers, but not parts of things. When you are counting items that
have parts less than one we use decimals.
Numbers are arranged into groups of three called periods. The
places within a period repeat (hundreds, tens, ones etc.) Starting at the
left, we read the three numbers in a period and then stop at the end of
each period and read the unit name before continuing on. The units
period does not have to be named when reading a number. We usually
separate the periods with commas.
Students need to develop conceptual understanding of numbers
larger than 1000. Even though models beyond 1000 are not readily
available, in order for students to develop a strong number sense they
need to manipulate physical models. It is difficult for students to fully
understand models pictured in books. Another important component
needed to develop number sense is to have students relate large
numbers to actual things in the world.
Intended Learning Outcomes: 6. Represent mathematical ideas in a variety of ways. Instructional Procedures: Invitation to Learn
Guess My Number
Tell the students that you are thinking of a twodigit number and
that both of the digits are different. Check to make sure that students
understand what “digit” means and what a “two digit number” is.
Explain that the students are to guess your number. Inform them that
you will keep track of their guesses and will give them clues to how
many digits are correct and if the digits are in the correct place. Draw
a three columned grid on the board to keep track of the guesses. Write
how many digits are correct (0, 1, or 2) and how many digits are in
the correct place (0, 1, or 2). (If one digit is correct, do not tell them
which one it is; just say one is correct.) As you play the game remind
the students to reflect on what they know about the number so far.
Why is it important that the digits are in the correct place? Does the
place change the value of the digit? For a more challenging game you
can have students guess a threedigit number. For example, let’s say
the number is 68.

Instructional Procedures
Part One – Place Value Patterns
 Ask students to write in their journals everything that they
know about our place value system. Give students about
five minutes to complete this assignment and then ask some
students to share what they wrote. Write some of their
responses on the whiteboard or use an overhead projector.
 After discussing some of their ideas, read the story A Million
Fish . . . More or Less. Then ask: “Could these things really
be true? How long would it take you to jump 5553 times?
Could a million fish fit in a wagon? How do you write half a
million?” Explain to the students that they will participate in
some activities to increase their place value knowledge.
 Use base ten blocks and review with students that a 1
centimeter cube represents the units or ones place. The tens
place is ten centimeter cubes connected in a 10 cm x 1 cm strip.
The hundreds place is represented by a square made up of 10
cm x 10 cm. Ask the students how they would represent the
thousands place? Does anyone notice a pattern? (Although the
thousand’s place is often represented with a larger cube, for this
activity the students need to see all of the centimeter squares
and so the pattern will be square, strip, square, strip, etc.)
 Tape ten of the hundred flats together. The strip should
measure 1m x 10 cm. Make sure that students are making the
connection that ten times the previous place makes the next
place. How could we model ten thousand? What shape would
it be? What would the dimensions be?
 Have students work in small groups to figure out the
dimensions of a ten thousand piece. (Ten one thousand strips
would go together to make a square that is 1 m x 1 m.) Work
together to complete a ten thousand square.
 If students are interested you can use a long piece of butcher
paper to make the next strip to represent one hundred
thousand. If you don't want to tape base 10 grids together you
can mark off ten 1m x 1m squares on butcher paper to show
how large one hundred thousand is. The strip would be 1 m x
10 m
 Extend the activity as far as students show interest. (See
extensions)
 Have the students discuss what they learned from the activity
about place value. Have them record their thoughts in their
journals.
Part Two – Reading large numbers
 Read the Bear Family story to the class.
 Explain to the class that when we read large numbers that we
first mark off the number in groups of three starting from the
right. We use a comma to separate these groups.
 Then starting at the left, we read the first group of numbers,
stopping at the end to name the family or in mathematical terms
the period. We do not need to name the units period.
 Put digits in the bear’s houses and have the students practice
reading numbers. (In fourth grade we only use the units house
and the thousands house, and the millions house.)
 Then ask the students: “What is the value of the digit in
the thousand’s place? The hundred’s place?” Check for
understanding.
 Explain to the students that numbers can be written in three
different ways: standard form, expanded form, and word form.
The following activity will give the students practice using
standard form and expanded form.
 Divide the students in partners. Pass out a whiteboard, a
marker, and one set of place value tents to each partnership.
Give the students an opportunity to look at the place value
tents. Ask the students what they notice about the tents?
(Hopefully students will point out that each digit shows its
value depending on its place. You can make numbers in
expanded form and standard form.)
 Have the partner groups model a threedigit number and check
for understanding. Continue to have students model larger
numbers that you say verbally. Call on students to reread the
number aloud and to read the expanded form of the number.
 Explain that in each group the students will take turns writing
or modeling large numbers. Have one student write a number
in standard form on the whiteboard while the other student
models expanded form using the place value tents. Students
should be saying the number aloud when it is their turn.
 Have the students switch roles and take turns going first.
 Remind the students using the tents that they can mixup the
order of the number to challenge their partners to write it
correctly.
Extensions:
 Model one million by drawing with chalk a 10 m x 10 m square
on the playground.
 Group students with mixed abilities together for group activity.
 Have students write in their journals before the activity and
after to explain what they have learned.
Family Connections
 Students could play “Guess my number” with a family member.
 Practice expanded and standard forms of numbers with a family
member using the place value tents.
 Have students go on a number hunt and find where large
numbers are used in the real world and share with the class.
Assessment Plan:
 Walk around the room while students are working on the
above activities and observe what they are doing and saying.
Are they able to read the numbers in standard and expanded
form? Or are they struggling and making errors? Can they use
the place value tents to form a number in expanded form? If
the expanded number is out of order can the student put it in
correct standard form?
 Assess students understanding during whole group discussion
from their comments. Are the comments correct or do they
have misconceptions?
 Assess students individually. Dictate several numbers for the
student to write in standard form and expanded form. Write a
number in expanded form or use the tents and mixup the place
value order and have the student put the number in correct
standard form. Have the student read numbers aloud.

Brain research has shown that physical movement – moving,
stretching, and acting out concepts, can increase the learning process.
Active learners remember the information longer and better than
sedentary learners. Teachers should have students: engage in a
variety of postures throughout the day, engage in movement during
class, use their bodies to demonstrate concepts, role play and include
a variety of physical activities to help students learn and if these ideas
are not possible then students should at least stop and stretch every 20
minutes.

Researchers believe that students learn and store information in two
different ways. The first form is a linguistic form where the learner
either listens to the information or reads it in a book. In the second
form, nonlinguistic, the learner forms a mental image or a physical
sensation by touching, smelling, listening, tasting, or kinesthetic
association. Research has shown that when students learn using both
forms their achievement improves greatly. After a nonlinguistic form
of learning has taken place students should be asked to explain and
justify what they have learned. When students are able to explain
their thinking and reasoning to others their knowledge increases and
they are able to recall it easier. Nonlinguistic representations include:
making physical models, using manipulatives, drawing pictures,
graphic organizers, or engaging in kinesthetic activities.
