(Math Journal 1, p. 17)
Have children share coin combinations. Record their combinations on the board using Î, Â, Í, and ‰. Some possibilities:
‰‰‰ÍÎÎÎÎ
ÍÍÍÍÍÍÍÍÂÎÎÎÎ
‰‰ÍÍÍÂÎÎÎÎ
Tell children that today’s lesson will review dollars-and-cents notation.
� Reviewing Dollars-and-Cents WHOLE-CLASS ACTIVITY
NotationAsk a volunteer to write 45 cents on the board in dollars-and-cents notation. $0.45.
● What does the 0 stand for? The number of dollars; there are none.
● What does the 4 stand for? The number of dimes, or 40 cents
● What does the 5 stand for? The number of pennies, or 5 cents
Ongoing Assessment: Informing Instruction
Watch for children who write $4.6 for 4 dollars and 6 cents and $0.8 for 8 cents.
Emphasize that in dollars-and-cents notation, the decimal point must be followed
by two digits. The first digit after the decimal represents the number of dimes; the
second digit represents the number of pennies.
Getting Started
Mental Math and Reflexes Have children count orally.
Count by dimes, beginning with 60¢: 60¢, 70¢, 80¢, 90¢, ...
Begin with $1.80: $1.80, $1.90, $2.00, ...
Count by nickels, beginning with 25¢: 25¢, 30¢, 35¢, ...
Begin with $2.45: $2.45, $2.50, $2.55, ...
Count by quarters; begin with 25 cents: 25¢, 50¢, 75¢, ...
Begin with $3.00: $3.00, $3.25, $3.50, ... Continue as time permits.
Math Message Do Problem 1 on journal page 17.
Home Link 1�9 Follow-Up Have children share their strategies for making the smallest and largest numbers they could.
Some children may benefit from doing the
Readiness activity before you begin Part 1
of the lesson. See the Readiness activity in
Part 3 for details.
NOTE Some children may be unfamiliar
with the Î, Â, Í, and ‰ notation. Show the
actual coins and match the appropriate nota-
tion to each coin. Point out that 2‰ means
‰ ‰.

Adjusting the Activity Provide coins for children to use during the lesson.
AUDITORY � KINESTHETIC � TACTILE � VISUAL
Adjusting the Activity A number of strategies can help with remembering the meaning of the > and
< symbols.
• Use various animal analogies, such as the
mouth must be open to swallow the bigger
number.
• The less than symbol looks like the finger
and thumb of the left hand. (Point out that
less and left have the same first letter.)
• Draw two dots by the larger number and
one dot by the smaller number. Connect
each of the two dots to the single dot, and
the symbol will be oriented correctly.
AUDITORY � KINESTHETIC � TACTILE � VISUAL
Remind children that 0.45 is an example of a decimal. The period between the 0 and the 4 is called a decimal point.
Repeat the process with 55 cents. Then dictate several amounts for children to record on their slates.
● 1 dollar and 18 cents $1.18 Circle the digit that shows the number of dollars. The first 1
● 2 dollars and 47 cents $2.47 Circle the digit that shows the number of pennies. 7
● 13 dollars and 80 cents $13.80 Circle the digit that shows the number of $10 bills. 1
● 4 dollars and 6 cents $4.06 Circle the digit that shows the number of dimes. 0
● 8 cents $0.08 Circle the digit that shows the number of dollars. The first 0
Continue until most children seem comfortable with writing amounts in dollars-and-cents notation.
Ongoing Assessment: Informing Instruction
Watch for children who write money amounts with both the $ and ¢, as in
$3.45¢. Remind them that when the $ sign and decimal point are used, it is not
necessary to use the ¢ sign.
� Reviewing the > and WHOLE-CLASSDISCUSSION
< SymbolsAlgebraic Thinking Ask children which amount is smaller—$1.28 or $1.40. $1.28 Write “$1.28 is less than $1.40” on the board.
● What is the symbol for is less than? < Write “$1.28 < $1.40” under the first statement.
● What is the symbol for is greater than? > Write “$1.40 is greater than $1.28” with “$1.40 > $1.28” under it.
Ask children to share their strategies for remembering the meaning of > and <.
Dictate two amounts, which children write on their slates with space between. Children then write the correct relation symbol between the numbers. Suggestions: $2.42 > $2.04; $13.30 > $3.08; $5.62 < $18.98. Repeat as needed.

(Math Journal 1, pp. 17 and 18;
Student Reference Book, p. 212)
Ask the class to turn to page 212 in the Student Reference Book. Review how a vending machine works: If the Exact Change light is on, you must put in the exact amount. If the light is off and you don’t have the exact amount, you may put in more than the exact amount, and the machine will make change.
Pose a making-change problem: Pretend that the Exact Change light is off. You want to buy a carton of grape juice for 45¢. How much change would you get if you put in a dollar bill? 55¢ Have children share their strategies.
Possible strategies:
� Count up from 45¢.
� Find the difference between 45 pennies and 100 pennies.
� Change a dollar to ‰ ‰ ‰ Í Í Â and take away 45¢ (‰ Í Í), leaving ‰ ‰ Â, or 55¢.
Have children work on their own or with a partner to complete both journal pages. When most children have completed the pages, briefly go over the answers.
For problems in which the amounts are written in words or shown
as coins, have children record the values above the words or illustrations
(See margin).

Ongoing Assessment: Journal
page 17 �Problems 8–10Recognizing Student Achievement
Use journal page 17 to assess children’s ability to compare values of coin
and bill combinations. Children are making adequate progress if they are able
to solve Problems 8–10 using coins. Some children may be able to complete
Problems 11 through 13 using coins. Still others may be successful without the
use of coins.
[Number and Numeration Goal 6]
Money skills will be revisited in Math Boxes exercises, but after Lesson 1-11, they will not be the focus of instruction.

� Playing Coin Top-It 15–30 Min
(Math Masters, p. 403; Student Reference Book, p. 270)
To provide experience with comparing totals for coin combinations, have children play Coin Top-It. Each player cuts apart a copy of Math Masters, page 403. Partners combine their cards to play Coin Top-It. If necessary, review the directions to Addition Top-It in the Student Reference Book and explain that players will use coin combination cards instead of number cards.
ENRICHMENT SMALL-GROUP ACTIVITY
� Sharing Money 5–15 Min
(Math Masters, pp. 25 and 399)
To apply children’s understanding of money concepts, have them work with coins and bills to solve a number story involving making change. They record their answers on Math Masters, page 25.
Planning Ahead
In Lesson 1-13, you will need data about the time the sun rises and sets. Collect this data each day until you start Lesson 1-13. You can find the information in local newspapers, on local newscasts, and on the Internet (www.sunrisesunset.com). Then fill in the table on Math Masters, page 404. Leave the Length of Day column blank. Prepare the class Sunrise/Sunset Chart. (See pages 910 and 911 in Volume 2 of the Teacher’s Lesson Guide.)
