Chapter 6 – 2-Digit Subtraction with and without
Regrouping (a.k.a. "borrowing")
We are currently working in chapter 6 of the math text.
Use the pages sent home to guide your work with your child.
The following concepts will be covered (not necessarily in this order):
Subtracting tens using a hundred chart.
Subtracting of 2-digit numbers with and without regrouping.
Using place-value models to regroup 2-digit numbers.
Following the steps in a process to solve story/word problems.
Choosing the correct operation to solve a problem.
Using addition to check subtraction.
Estimate (using rounded addends) to see if an answer is reasonable.
Subtracting money amounts.
It is very important that the children practice math facts to 12 or even 20.
That means learning all addition and subtraction facts with answers up
to 12 or 20 by heart. This will make the addition that we work on in this
chapter much easier.If your child is using fingers to count out simple
addition facts to 12, they will struggle with these concepts in chapter 5.
Use flash cards and make a game of it. I sent home some ideas for
you and have many more if you need them. Just ask! I am here to help
you to work together with your child at home. Your support of our
lessons helps to reinforce the concepts. Thank you!
Remember to study facts for addition and subtraction with your child as
often as you can!
