Advance PreparationFor Penny Plate in Part 2, obtain paper plates or other open-top, opaque containers. During the game, children

will turn the containers upside down and arrange as many as 20 pennies on the containers’ bottoms. Make sure

the bottom of each container is wide and sturdy enough to hold the pennies.

1 Teaching the Lesson

� Math Message Follow-Up WHOLE-CLASS ACTIVITY

(My Reference Book)

Have children briefly share some interesting things that they found. Discuss ways in which My Reference Book can be helpful.

With the class, look up the Table of Money Equivalencies in My Reference Book. Ask children simple questions regarding money equivalences. For example, ask: How many pennies in a dime? 10 How many nickels in a dime? 2 How many nickels in a quarter? 5

Discuss the sections of My Reference Book.

The Table of Contents may be used to find information about a particular topic. The Table of Contents also gives the page number of the first page of a topic.

Use the Table of Contents to look up information on clocks on pages 78 and 79. Discuss the information in My Reference Book regarding clocks. Be sure to allow the children enough time to explore the clock section.

Explain to the children that in today’s lesson they will see how My Reference Book can be helpful to them as they work in their Math Journals.

� Introducing Math Boxes WHOLE-CLASSDISCUSSION

(Math Journal 1, p. 7)

Ask children to name activities that people practice. Sample answers: Dancing, singing, playing a musical instrument, speaking a foreign language, playing basketball and other sports, and so on

Getting Started

Mental Math and Reflexes On slates,

Write all the 1-digit numbers. How many are there? 10

Write two 2-digit numbers. Circle the larger one.

Write two 3-digit numbers. Circle the digit in the ones place and put an X on the digit in the hundreds place.

Math Message Spend a few minutes looking through your My Reference Book. Be ready to share something you found interesting. Think about how this book can be helpful to you.

NOTE 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.

Ask children: What would happen if people never practiced? Is anyone familiar with the expression, “Practice makes perfect?” What does this mean?

Explain that practice is necessary in mathematics, too. In Everyday Mathematics, one of the ways to practice is by doing a page of problems called Math Boxes.

Have children turn to journal page 7. Call children’s attention to the My Reference Book icon in the Math Boxes. Discuss how this icon tells them which page to go to in My Reference Book if they need more information to complete the Math Boxes.

NOTE For practice estimating collections of objects, see

www.everydaymathonline.com.

� Completing a Math Boxes Page INDEPENDENTACTIVITY

(Math Journal 1, p. 7)

Mixed Practice Go over each problem so children understand what to do. Children complete the journal page independently or with a partner. When children have finished, briefly discuss the answers.

2 Ongoing Learning & Practice

� Playing Penny Plate PARTNER ACTIVITY

(Math Masters, p. 468; My Reference Book,

pp. 146 and 147)

Algebraic Thinking Have children read the rules for Penny Plate on pages 146 and 147 in My Reference Book and play the game in partnerships. Playing this game frequently will help develop children’s automaticity with sum-equals-ten facts.

Ongoing Assessment: Informing Instruction

Watch for children who are having difficulty determining the number of pennies.

Suggest that they draw circles to represent all of the pennies. Then suggest that

the children use one of the strategies below to figure out how many pennies are

under the plate:

� Cross off one circle for each penny on top of the plate. Count the uncrossed

circles to find the number of pennies under the plate.

� Use a second set of pennies as markers. Cover one circle for each penny on

top of the plate. Count the uncovered circles to find the number of pennies

under the plate.

2. Player 2: • Counts the pennies on top of the plate. • Figures out how many pennies are hidden

under the plate.

3. If the number is correct, Player 2 gets a point.

4. Players trade roles and repeat Steps 1 and 2.

5. Each player keeps a tally of their points. The first player to get 5 points is the winner.

Another Way to Play

Use a different number of pennies.

I see 6 pennies.There are 10 pennies in all.So there are 4 penniesunder the plate.

Ongoing Assessment: Math Masters,

page 468 �Recognizing Student Achievement

Use Math Masters, page 468 to assess children’s ability to solve sum-equals-

ten facts. Children are making adequate progress if they can name the number

of pennies under the plate without actually counting the pennies. Some children

may be able to write a number model that represents each round.

READINESS PARTNER ACTIVITY

� Playing Two-Fisted Penny 5–15 Min

Addition

To explore finding sums to ten using a concrete model, have children play Two-Fisted Penny Addition. Children count out 10 pennies and split them between their two hands. Help children identify their left and right hands.

Call on several children to share amounts. For example:

� My left hand has 1 penny and my right hand has 9 pennies.

� My left hand has 3 pennies and my right hand has 7 pennies.

The various splits can be recorded on the board.

Repeat with other numbers of pennies. Partners can continue to practice using different total numbers of pennies: 9, 12, 20, and so on.

EXTRA PRACTICE SMALL-GROUP ACTIVITY

� Minute Math + 5–15 Min

To offer children more experience with complements of 10, as well as with 2-, 3-, and 4-digit numbers, see the following pages in Minute Math+: pp. 9, 23, 32, and 33.
