Dear Family,My class started Chapter 7 this week. In this chapter, I will learn about the values of coins and how to find the total value of a group of money. I will also learn how to tell time on analog clocks and digital clocks.Love,
Vocabulary
penny a coin with a value of 1 cent
nickel a coin with a value of 5 cents
dime a coin with a value of 10 cents
quarter a coin with a value of 25 cents
dollar an amount equal to 100 cents
minute a unit of time
Home Activity
With your child, set up a play store together. Use objects such as food items or small toys. Put price tags on each object, using amounts less than one dollar. On a sheet of paper, have your child write the price of an object and then draw a group of coins that has that as its total value. Take turns doing this for several objects.
LiteratureReading math storiesreinforces ideas. Look for these books at the library.
