AC9M3N01: Recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000

Large numbers are organised in groups of three digits. Each digit has a place value, and the same number can be renamed without changing its total value.

Learning routine: Read the periods → Build place value → Rename → Compare → Order → Explain

Success looks like

• Read numbers beyond 10 000
• Write number names
• Use place value
• Rename numbers
• Compare and order

Success criteria:

• Read numbers beyond 10 000
• Write number names
• Use place value
• Rename numbers
• Compare and order

Students should be comfortable reading and representing whole numbers, using place value, and explaining simple addition, subtraction or equal-group relationships from earlier years. Begin with a short concrete or visual recall task before moving to Numbers Beyond 10 000.

Key idea: Large numbers are organised in groups of three digits. Each digit has a place value, and the same number can be renamed without changing its total value.

Learning routine: Read the periods → Build place value → Rename → Compare → Order → Explain

place value

the value a digit has because of its position

numeral

a written symbol or group of digits that names a number

natural number

a whole number used for counting

What is the big idea in this topic?

Large numbers are organised in groups of three digits. Each digit has a place value, and the same number can be renamed without changing its total value.

What routine should I use?

Read the periods → Build place value → Rename → Compare → Order → Explain

How do I know I am ready to move on?

You can read numbers beyond 10 000, write number names, use place value, rename numbers, compare and order and explain how your model or calculation supports the answer.

• Dropping a zero — A zero can hold an empty place, as in 42 507.
• Comparing from the ones — Start at the highest place value.
• Reading every digit separately — Read the number in periods: thousands, then ones.

1. Which numeral means forty-two thousand five hundred and seven?

   • 42 507
   • 4 257
   • 425 070
   • 42 057

2. Complete the place-value statement.

   Prompt: 63 409 has □ ten-thousands, □ thousands, □ hundreds, □ tens and □ ones.

3. Which number is greatest?

   • 48 900
   • 48 090
   • 48 009
   • 40 899

4. Write 52 080 in words and explain the role of the zero digits.

5. Match each numeral to its number name.

   Match: 23 006 • 32 060 • 230 006 ↔ two hundred and thirty thousand and six • twenty-three thousand and six • thirty-two thousand and sixty

6. Complete the expanded form.

   Prompt: 47 305 = 40 000 + 7 000 + □ + 5

1. Create three different renamings of 24 350 using thousands, hundreds, tens and ones. Explain why the value stays the same.

2. Write clues for a five-digit mystery number with 7 in the thousands place and 0 in the tens place. Make the clues identify exactly one number.

Explain the reasoning, not only the final answer.

1. Order 39 999, 40 009, 40 090 and 39 909 from smallest to largest.

2. A student says 50 206 is the same as 5 026 because both use 5, 2 and 6. Explain the error.

Review hint: Follow the routine “Read the periods → Build place value → Rename → Compare → Order → Explain” and use the worked model to check whether your answer is reasonable.

• I can read numbers beyond 10 000.
• I can write number names.
• I can use place value.
• I can rename numbers.
• I can compare and order.

Quick check: Read 63 409 aloud. • Write fifty-two thousand and eighty as a numeral. • Which is greater: 48 090 or 48 900?

The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning.

• Content description: recognise, represent and order natural numbers using naming and writing conventions for numerals beyond 10 000
• E1: moving materials from one place to another on a place value model to show renaming of numbers; for example, 1574 can be shown as one thousand, 5 hundreds, 7 tens and 4 ones, or as 15 hundreds, 7 tens and 4 ones
• E2: using the repeating pattern of place value names and spaces within sets of 3 digits to name and write larger numbers: ones, tens, hundreds, ones of thousands, tens of thousands, hundreds of thousands, ones of millions, tens of millions; writing, for example, four hundred and twenty-five thousand as 425 000
• E3: predicting and naming the number that is one more than 99, 109, 199, 1009, 1099, 1999, 10 009 ... 99 999 and discussing what will change when one, one ten and one hundred is added to each
• E4: comparing the Hindu-Arabic numeral system to other numeral systems; for example, investigating the Japanese numeral system, 一、十、百、千、万
• E5: comparing, reading and writing the numbers involved in the more than 60 000 years of First Peoples of Australia’s presence on the Australian continent through time scales relating to pre-colonisation and post-colonisation
