Ordering numbers and place value
- Always look at big numbers In groups of 3
- Always start from the right hand side of the number
- Moving left put a space in every 3 digits to break it up into groups of 3
- Now going right read each group of 3 and on the first add million and going down from there
- Putting numbers in Oder of size
- Depending on which way you are going increase or decrease
- If you are increasing you start from small to big so you start with the 2 digit numbers and you go up
- For decimals we do the same first bit
- But then you have to look what is after the point a 0 or a 1
- First group the 0 numbers and then group the 1 numbers
- Addition / subtraction and decimals
- Line up the units and the columns so you don't get mixed up
- Then add the column starting on the right and then to the left
- Then you carry over any spare numbers when you are adding
- You do the same for subtraction but you are taking away
- Decimals are the same but you have to add the stuff on the right hand side of the point and the the left
