Quick Review of Our Place Value Chart

M HTh TTh Th H T O
5 4 3 2 1 8 9

This is 5,432,189 - but how do we READ it?

The Secret Is Grouping in Threes

Large numbers are read in groups of three:

5 | 432 | 189

  • Group 3: Millions (leftmost)
  • Group 2: Thousands (middle)
  • Group 1: Ones (rightmost)

Reading 5,432,189 Group by Group

The number 5,432,189 split into three labeled groups of digits: millions, thousands, and ones

Break it down, group by group!

Reading Each Group in Order

5,432,189

Group Digits Read As
Millions 5 "Five million"
Thousands 432 "four hundred thirty-two thousand"
Ones 189 "one hundred eighty-nine"

Putting the Full Reading Together

5,432,189

"Five million, four hundred thirty-two thousand, one hundred eighty-nine"

Notice the commas after "million" and "thousand"!

Let's Practice Reading This Number

1,234,567

Break into groups: 1 | 234 | 567

  • "One million"
  • "two hundred thirty-four thousand"
  • "five hundred sixty-seven"

Reading Numbers That Contain Zeros

8,005,020

Break into groups: 8 | 005 | 020

  • "Eight million" ✓
  • "five thousand" (skip the zeros!)
  • "twenty" (skip the hundreds!)

"Eight million, five thousand, twenty"

When a Whole Group Is Zero

6,000,001

Break into groups: 6 | 000 | 001

  • "Six million" ✓
  • Skip the thousands (all zeros!)
  • "one" ✓

"Six million, one"

Your Turn: Read These Numbers

Practice reading with a partner:

  1. 3,456,789
  2. 7,020,040
  3. 9,000,009

Checking Your Answers from Practice

  1. 3,456,789 = "Three million, four hundred fifty-six thousand, seven hundred eighty-nine"

  2. 7,020,040 = "Seven million, twenty thousand, forty"

  3. 9,000,009 = "Nine million, nine"

Writing a Number Out in Words

Let's write 2,345,678 in words:

Step 1: Break into groups: 2 | 345 | 678

Step 2: Write each group:

  • Two million
  • three hundred forty-five thousand
  • six hundred seventy-eight

Three Rules for Writing Words

  1. Use commas after "million" and "thousand"

  2. Hyphenate 21-99: twenty-one, thirty-five, ninety-nine

  3. Don't use "and" in whole numbers

    • Wrong: "three hundred and five"
    • Right: "three hundred five"

Watch Out for These Spellings

Watch these tricky ones:

Wrong Right
fourty forty
ninty ninety
eigth eight
tweleve twelve

Converting from Words to Figures

"Four million, two hundred thirty-five thousand, six hundred nine"

Group Words Figures
Millions Four million 4,000,000
Thousands two thirty-five thousand 235,000
Ones six hundred nine 609

Answer: 4,235,609

Watching Carefully for Missing Zeros

"Seven million, forty thousand, three"

  • Seven million → 7,,
  • Forty thousand → ,040,__
  • Three → ,__,003

Fill in zeros for missing places!

Answer: 7,040,003

Your Turn: Convert Words to Figures

Write in figures:

  1. "Three million, five hundred thousand, two hundred"

  2. "Eight million, sixty, four"

  3. "One million, one thousand, one"

Checking Your Figures from Practice

  1. "Three million, five hundred thousand, two hundred" = 3,500,200

  2. "Eight million, sixty, four" = 8,000,064

  3. "One million, one thousand, one" = 1,001,001

Partner Practice: Say It, Write It

Partner A: Say a number in words
Partner B: Write it in figures

Then switch! Check each other's work.

Quick Quiz: Write in Words

Question 1:
Write in words: 4,567,890

The Answer, Written in Words

4,567,890 =

"Four million, five hundred sixty-seven thousand, eight hundred ninety"

Quick Quiz: Write in Figures

Question 2:
Write in figures:

"Nine million, five hundred, four"

Answer: Filling In the Missing Group

"Nine million, five hundred, four"

  • Nine million → 9,000,000
  • Five hundred → 500
  • Four → 4

= 9,000,504

Quick Quiz: Write in Words Again

Question 3:
Write in words: 3,002,050

Another Answer, Written in Words

3,002,050 =

"Three million, two thousand, fifty"

(Skip the hundred thousands - it's zero!)

Large Numbers Show Up in Real Life

Large numbers are everywhere!

  • Uganda's population: about 48,000,000
  • A new car: about 80,000,000 shillings
  • Distance to the moon: about 384,000,000 meters

Can you read these numbers?

Summary: Reading and Writing Large Numbers

  1. Group digits into threes (from the right)
  2. Read each group, then say its name
  3. Skip groups that are all zeros
  4. Use commas to separate groups in figures

Key Points from Today to Remember

  • Millions | Thousands | Ones - the three groups
  • Commas separate the groups
  • Skip zeros when reading
  • Fill in zeros when writing figures
  • Don't use "and" in whole numbers
