I hope that yesterday's work went ok and that you can understand by seeing the answers anything that wasn't quite right.
Today's work is about rounding numbers. It's a while since we did this so time for a recap:
1. Remember that 1,2,3,4 round down as they are nearer to the previous 10, 100 or 1000.
2. The numbers 6,7,8,9 round up as they are nearer to the next 10, 100, or 1000.
3. 5 is the same distance from both numbers, so it needs a rule. The rule is: It rounds up.
On the number line above, all numbers up to the red dot (at 4) would round back to the previous 10 100 or 1000 and anything after that rounds up.
Let's do an example:
If you are rounding to the nearest 1,000 as you are for these activities, you will need to start by looking at the number in the hundreds column to see if it is above or below 4.
In this case it is a 9 so it will go up to the next thousand.
When you know this, and have decided whether to round up or down, check the thousands digit so you know whether to stick with that digit (if we round down) or add 1 to it (if we round up).
In this case we are rounding up so you need to add 1 to the thousands column.
So 6,995 rounded to the nearest 1,000 is 7,000
