Have chidren use actions and words to respond. What woud you do first to find the tota vaue of this group of coins? Start with 25 since that is the vaue of the quarter. What woud you do next? Possibe answer: A dime is 10. Count on 10 to get 35. Then what woud you do? Possibe answer: Count on 5 more for the nicke to get 40. Repeat the activity with other groups of coins and have chidren describe how they woud find the vaue of each group of coins.

Have them put the pennies in ten frames to aid in counting. Suppose that I have another quarter. How can I show the vaue of 2 quarters with pennies? Trade the second quarter for 25 more pennies. Have chidren make the trade and add the pennies to the ten frames. How many pennies have the same vaue as 2 quarters? 50 pennies What is the tota vaue of the 2 quarters? 50 You may wish to repeat with a third, then a fourth quarter. FL25B

Have chidren count again and write the numbers as they count each coin. How woud you find the tota vaue of a dime, a penny, and a quarter? Start with the quarter because it has the greatest vaue, then count on the dime and the penny: 25, 35, PRACTICE Share and Show Guided Practice Exercises 1 3 give chidren an opportunity to count on from a quarter to find the tota amount. Look at Exercise Why do you start counting at 25? A quarter has a vaue of 25 cents. Exercises 2 and 3 may be used for Quick Check.

Enrich EFL7 Grade 1 Houghton Miffin Harcourt Pubishing Company COMMON ERRORS Error Chidren may have difficuty counting more than 1 quarter. Exampe In Exercise 2, chidren may not know how to count 25, 50, 75. Springboard to Learning Suggest that chidren draw 3 quarters in a row and write the counting sequence beow the coins: 25, 50, 75. Aow chidren to refer to their drawing as they earn to count using quarters. FL26

5 c On Your Own Independent Practice If chidren answered Exercises 2 and 3 correcty, assign Exercises 4 8. They can use their MathBoards to continue to write vaues as they count if they need to. Probem Exercise 8 requires higher order thinking as chidren count 4 quarters. Go Deeper To extend thinking, have chidren write a two-digit number on each of three index cards. Have partners exchange the cards and use coins to find combinations that make each tota vaue. Chaenge chidren to find combinations that use the fewest coins. Suggest to start by showing the amount in a way that is easy for them, then trade coins unti no more trades can be made. On Your Own Count. Write the tota vaue Houghton Miffin Harcourt Pubishing Company Chapter 9 Lesson 9C FL27 Cross-Curricuar SCIENCE SOCIAL STUDIES Materias rea pennies, back construction paper, chak or white crayon Discuss the sun and how it functions as an energy source. It can cook food, warm our bodies, and hep pants grow. Te chidren you are going to do an activity that uses energy from the sun. Each chid gets a piece of back construction paper and some pennies. Have them write their names on the paper using chak or crayon. Find a sunny spot outside, set papers on the ground, and have chidren pace pennies in a design on their piece of paper. Coins shoud not overap. Leave the designs in the sun for a few minutes, or onger. Papers shoud be kept in a safe pace if you are going to eave them. Bring papers in and remove the coins. The energy from the sun shoud have faded the paper that was not covered by the coins. Materias severa exampes of state-specific quarters Provide exampes of severa state quarters. Hep chidren notice that the fronts are the same, but the backs are specific to a state. Discuss different images seen on the backs of the quarters and discuss that states chose their designs to represent things about their state. Have chidren design and draw the back of a quarter to represent your cassroom. Ask vounteers to share their designs and expain how they represent the cass. FL27 Chapter 9

6 PROBLEM SOLVING Use coins. Write different ways to make 50. Check chidren s work. Possibe answer: 2 quarters, 0 dimes, 0 nickes, 0 pennies c Probem Soving Probems In Exercises 9 15, chidren use higher order thinking skis to sove this non-routine probem. If chidren have difficuty getting started, you might suggest they use a pattern, or think about trading coins. Point out that there are more combinations than wi fit in the tabe. Test Prep Coach Test Prep Coach heps teachers to identify common errors that chidren can make.
