1. This document discusses place value and rounding numbers. It explains that in the number 5,624: thousands place is 5, hundreds is 6, tens is 2, and units is 4. 2. When writing numbers with thousands, there should always be 3 digits after the thousands place. For example, 5,624. 3. When writing numbers with millions, there should always be 6 digits after the millions place. For example, 5,000,000. The document then provides examples of rounding 874 to the nearest 10 (rounds down to 870) and nearest 100 (rounds up to 900), explaining the rules for rounding down or up based on the digit in the tens or hundreds

1. Place Value Book 5 NT1 - (N1 pg. 7)
1. Thousands Hundreds Tens Units
5 6 2 4
Five thousand six hundred and twenty four.
2. A thousand should always have 3 digits after it.
ex. 5, 624
3. A million should always have 6 digits after it.
ex. 5, 000 000
The value of numbers:
The value of the number 2 is:
ex: 32,574 = 2, 000
14,298 = 200

2. Rounding to the nearest 10 NT1 - (N2 pg. 7)
874
____________________________________________
870 71 72 73 74 75 76 77 78 79 880
Which is the 10 before it? Which is the next 10?
874 is nearer 870
We have rounded the number down.
Remember
To round to the nearest 10
0 - 4 round the number down
5–9 round the number up

3. Rounding to the nearest 100 NT1 - (N2 pg.8)
874
______________________________________
800 10 20 30 40 50 60 70 80 90 900
Which is the 100 before it? Which is the next 10?
874 is nearer 900
We have rounded the number up.
Remember
To round to the nearest 100
0 - 49 round the number down
50 – 99 round the number up
