Remember the 3 rules!!

Aiyo!!! I really had a hard time marking your class activity books. I find that quite a few of your have made careless mistakes. Okie We shall have a revision lesson on Monday!! Remember the 3 rules in doing rounding up of numbers?? Okie let's do a recap once again.

Step 1 : Check what the question is asking for. (e.g. are they asking for rounding up to the nearest tens/hundreds/thousands?)

Step 2 : Look at the DIGIT next to the place value of the question. ( if question ask for hundreds you look at the tens, if they ask for tens you look at the ones). Next if its 5 or more , we round up, if not we round down.

Step 3 : If the question wants us to round off to the nearest hundred, the tens and ones become 0, if they want us to round off to the nearest tens then the ones become 0.

Okie? Cool everyone? = )
