Place value and big numbers: I can read and write big numbers, say what each digit is worth, and compare and round them.
Here are place value counters: 3 thousands, 4 hundreds, 2 tens and 5 ones.
3,425 = 3,000 + 400 + 20 + 5
We read 3,425 from the left: three thousand, four hundred and twenty-five.
The digit 3 stands for 3 thousands, so its value is 3,000. The 4 is worth 400.
Picture: Place value counters showing 3,425: 3 thousands, 4 hundreds, 2 tens and 5 ones. It is split into 3,000, 400, 20 and 5.
Your turn: These counters make 6,152. What is the value of the digit 5 in 6,152?
Picture: Place value counters with 6 thousands, 1 hundred, 5 tens and 2 ones.
Choose one:
- 5
- 50
- 500
- 5,000
Answer
The answer: 50
50. The digit 5 stands for 5 tens, and 5 tens are worth 50.
Picture: Place value counters showing 6,152: 6 thousands, 1 hundred, 5 tens and 2 ones. It is split into 6,000, 100, 50 and 2. The tens column is highlighted.
In a place value chart, Th is thousands, H is hundreds, T is tens and O is ones.
Five thousand and seventy has 5 thousands and 7 tens.
It has no hundreds and no ones, so we write 0 in those columns.
