2 Lesson 152 MATH Instruction Pennies, Nickels, and Dimes Today you will learn more about pennies, nickels, and dimes. Look at your coins. penny nickel dime Pick out a penny. It is the only coin that has a copper color. Pick out a nickel. A nickel is silver. A nickel is bigger than a penny. The edge of a nickel is smooth. Pick out a dime. The dime is the smallest coin. It is also silver. The dime has a rough, bumpy edge. Each coin has 2 faces (sides). Some newer coins have different faces than the older coins. Each coin has a value. The value of the coin is how much money it is worth. What is the value of a penny? 1 cent, or 1 Do you know the value of a nickel? 5 cents, or 5 Do you know the value of a dime? 10 cents, or Lesson 152 Grade 1 MATH Calvert Education

3 MATH Lesson 152 Counting the Value of Different Coins You can find the value of a group of coins that are not all the same. Start with the coin that has the greatest value. Then use skip counting or count on to find the value of the group of coins. Start with the nickels. Use your coins or point. Count by 5s: 5, 10, 15. The value of the 3 nickels is 15 cents. Count on the pennies. 16, 17, 18 = The value of the 3 nickels and the 3 pennies is 18. To the Learning Guide Provide your student with different groups of pennies, dimes, and nickels. Start with sets of dimes and pennies or of nickels and pennies. If your student is comfortable with these groups of coins, have him count sets of dimes and nickels and then dimes, nickels, and pennies. Have him skip count and count on to find the value of the group of coins. If your student struggles to skip count and count on within the same set of coins, have him stop after he skip counts the coins of greater value. Guide him to write the value of the greater coins on a piece of paper. Then ask which number would come next. He can then begin from that number, counting by 1s.

4 Lesson 152 MATH If your student has difficulty keeping track of the different amounts, he can use another method. Have him line the coins up from greatest to least on a piece of paper, or use a picture of the coins. He will put a mark on each coin that represents 5. So a dime would have 2 marks and a nickel would have 1 mark. Then draw a line to separate the pennies. After the coins are marked, he will count the marks by 5, then pause, and count on with the pennies Practice Read and complete pp in Math in Focus. Then complete pp in Workbook.

The value of a penny is 1. A nickel is silver-colored. It is bigger than a penny. The value is 5. A dime is also silver-colored. It is the smallest coin. The value is Lesson 152 Grade 1 MATH Calvert Education

5 MATH Lesson 152 Counting the Value of Coins Count by 1s to find the value of a group of pennies. Skip count by 5s to find the value of a group of nickels. Skip count by 10s to find the value of a group of dimes. Counting the Value of Different Coins You can find the value of a group of different coins. = Skip count to find the value of dimes and nickels. Count on to add the value of the pennies.
