0, 1, 2, 3, 4, 5, 6, 7, 8, 9
We all recognise and know these ten digits, but do we realise just how clever they really are?
We know that in the number 432, the digit 2 is worth 2
Now, let's change the digits around to make 234.
Now the 2 is worth 200!
I bet you can work out what the 2 will be worth in 324.
It's worth 20.
Did you get it correct?
Now, let's look at some word problems using some of these digits.
John says that 432 is the highest number he can make using these three digits.
Let's see if he's right!
We can see that 4 is the highest digit, then 3, and finally the 2 in the one's column.
Well done John, you're right!
Sara says that if she adds ten to 753, she will have 754.
Let's have a look at this.
If we add 10 to the number, it is the tens column that will change.
753 + 10 = 763
The ones column will stay the same. Better luck next time Sara!
Now, why don't you have a go at some more word problems - good luck!
