Mathematics · Number Representation & Place Value · conceptual
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones
What mastery looks like
- State the value of each digit in a three-digit number (e.g. in 362, the 3 represents 3 hundreds)
- Partition a three-digit number into hundreds, tens, and ones (e.g. 485 = 400 + 80 + 5)
- Explain why 706 has 7 hundreds, 0 tens, and 6 ones
Check your understanding
If The three digits of a three-digit number sees the number 348, can they tell you there are 3 hundreds, 4 tens, and 8 ones — rather than just reading the digits as 'three four eight'?
