Homework

I just remembered that I didn't get a chance to explain the homework that was sent home today. ]

The math is something that they haven't seen yet: Order of Operations
Here's how it works
7 x 2 - (3 + 8) =
First you need to do what is in the parenthesis (3+8) = 11
7 x 2 - 11
Then you have to do the multiplication or division 7 x 2 = 14
14 - 11
Then solve the addition or subtraction 14 - 11 = 3

Therefore:   7 x 2 - (3 + 8) = 3

Note: Always do it in this order
Parenthesis
multiplication and division from left to right
addition and subtraction from left to right.

16 / (16 - 4 x 2) solve for 4 x 2
16 / (16 - 8) solve for (16 - 8)
16 / 8 solve the division
16 / 8 = 2

If you or your child has any other questions, please feel free to email me tonight or tomorrow and I can help...or bring in your questions on Monday.

I'm going to try allowing comments on the blog. If you'd like to make a comment feel free. This is a school so keep it safe. One thought is people could comment on the blog if they have an idea or volunteer for something. Thanks!
