Introduction/Focus:
• Remember when we talked about Shirley
Temple on Monday?
• Draw a place value chart for your whole
numbers.
• Leave room on the right to add more numbers
to the chart.
• These numbers will be the decimals.
Guided Practice: (DOK 1 and 3)
• How do we read and write decimal numbers
to the thousandths?
Look at this place value chart:
246.93 is read two hundred forty-six and ninetythree hundredths.
93.217 is read ninety-three and two hundred
seventeen thousandths.
Follow these steps to Read and Write

1. Read the whole amount (# to the left of the
decimal).
2. Say the word “and” for the decimal point.

Independent work/Activity:
• Cut a piece of cardstock or construction paper into two
pieces. Use one piece for each two students in the class.
Vary the shape and design of the cut to resemble a jigsaw
puzzle piece. On one piece of the paper write a number
and on the other piece write the corresponding number
word. Shuffle all the cards and give them each a piece of a
card. Have students work together to find the student that
has the number or number word that matches their piece.
The pieces that correspond to each other should fit
together like a jigsaw puzzle. Have pairs of students show
their cards and state their number and number word. Have
the class discuss whether they agree or disagree with the
pair.
