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
Decimals:
1. Read the whole amount (# to the left of the
decimal).
2. Say the word “and” for the decimal point.
3. Read the number after the decimal point.
4. Say the place value word of the last digit.

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.
