~ Wednesday: Estimation ~

Estimation:

373 x 4

You have to round off 374 into a number that is easiest for you to do the multiplication.

So you round it off to the nearest hundred, you will get

400 x 4 ~ 1600


* Always remember to round off the number into another number that you can multiply easily(mentally) when doing an equation that involves estimation.


Homework:
1) Math Activity Book do until Pg.44
