Subtraction with Regrouping

Parents and followers of this blog:

Subtraction is this weeks topic.

Keywords: take-away, subtract, minus, remove, more than, left...

This week our class is going to concentrate on double minus single digit problems...
eg. 57

-8
---------------

Parents please note some changes in terms we used to use(old school)

"borrow" I going to borrow one from the 5 and make 7 a 17.

we now say " regroup" We are going to move 1 ten from 5 and add 10 to 7, to make 17...

As you know the regrouping (borrowing) part is a difficult process to understand but with
practice I know your child will succeed.

Monday and Tuesday we will have practice worksheets on subtraction.
Wednesday we will resume with Unit 9...
