Lesson 4

Problem 1Write a four-digit number in expanded form.

1,708Hundred

thousandsTen

thousandsThousands Hundreds Tens Ones

• On your place value chart write the following number: 1,708.• What is the value of the 1?

1,000

.• What is the value of the 7? .

• What is the value of the 0? .• What is the value of the 8?

700 8

• What is the value of 1,000 and 700 and 8?• So 1,708 is the same as 1,000 plus 700 plus 8.• Write a number sentence to show that equation.

• 1,000 + 700 + 8 = 1,708

Lesson 4

Problem 2Write a five-digit number in expanded form.

27,085Hundred

thousandsTen


7,000 80 5

• Why is there no term representing the hundreds?• With your partner write an addition sentence.• Now read the expanded sentence with me.

• You said, “twenty-seven thousand, eighty five.”• What did you notice about where I placed a comma in both the standard form and the word form?

20,000

Show the value of

each digit at the

bottom of your

place value chart.

Lesson 4

Problem 3Transcribe a number in word form to standard and expanded form.

Two hundred seventy thousand, eight hundred fifty Hundred

thousandsTen

thousandsThousands Hundreds Tens Ones• Read this number. Tell your

partner how you can match the word form to the standard form?

• Everything you say, you should write in words.

• The comma helps to separate the numbers in the thousands from the numbers in the hundreds, tens, and ones.

• Write this number in your place value chart.

• Now, write this number in expanded form. Tell your partner your equation.

200,000 + 70,000 + 800 + 50 equals 270,850.

Repeat with sixty-four thousand, three.

Lesson 4

Problem 4Convert a number in expanded form to word and standard form.

700,000 + 8,000 + 500 + 70 + 3 Hundred

thousandsTen


7 8, 5 7 3

• Read this number statement. On your own, write this number in your place value chart.

Seven hundred eight thousand, five hundred seventy-three.

Repeat with 500,000 + 30,000 + 10 + 3.

7 0 8, 5 7 3• My sum is 78,573. Compare your

sum with mine.

• Read this number in standard form with me.

• Write this number in words. Remember to check for correct use of commas and hyphens.

Lesson 4

Your 7 is in the wrong place! The

value of 7 is 700,000. You have

it as 70,000.

Lesson 4

Student DebriefLesson Objective: Read and

write multi-digit numbers using base ten numerals,

number names, and expanded form.

• Compare the numbers in Problems 1 and 2. What do you notice?

• As you completed the chart on Page 2, what number words were tricky to write? Which number words can be confused with other number words? Why? What strategies did you use to spell number words?

• Timothy and his dad read a number word in two ways. What other numbers can be read more than one way? Which way of reading a number best helps you solve? When?

• Two students discussed the importance of zero. Nate said that zero is not important, while Jill said that zero is extremely important. Who is right? Why do you think so?

• What role can zero play in a number? • How is expanded form related to the standard form of

a number? • When might you use expanded form to solve?
