Double and Triple Digit Subtraction Worksheets

When we are working with students to find these types of differences it can be a bit confusing for them because we spend a good amount of the time focusing on borrowing and regrouping place values. Our advice is to start with problems that have no regrouping. You will find these types of problems in our independent practice worksheets. Once they have a good taste of success without borrowing, introduce borrowing and regrouping when this occurs. Again, we want to baby step them in so make sure the borrow comes from the tens place and once they have that down pat, move on to borrowing from the hundreds place. When you feel that students have pretty much conquered those types of problems move on to double borrowing problems. That is where you need to borrow from both the hundreds and tens place. This is a collection of worksheets and lessons that shows students how to find the difference between a three- and two-digit value.

Aligned Standard: 2.NBT.B.7

  • Answer Keys - These are for all the unlocked materials above.

Homework Sheets

We go with the left to right orientation here. Once they have that down, vertical format is a luxury for them.

  • Homework 1 - These are setup in a horizontal fashion with bold numbers.
  • Homework 2 - The numbers are even bolder now.
  • Homework 3 - This should make it easier to track and follow through it.

Practice Worksheets

A standard setup here for your students.

  • Practice 1 - We pitch it over to vertical orientation.
  • Practice 2 - This is the easiest font to track these in.
  • Practice 3 - Start with the column that is deepest to the right.

Math Skill Quizzes

I used an oversized font to allow you to easily work it out.

  • Quiz 1 - Take some value away from all of this.
  • Quiz 2 - Let's see how much we know up to here.
  • Quiz 3 - Lots of borrowing is going on for these problems.

How to Subtract a Two Digit from Three Digit Value

231 - 26 Worked Out

When you are teaching your children about subtraction, you need to be extra careful when you are subtracting a 2-digit number from a 3-digit one. Your child must know about the concept of place values well. Since we will place the value ones and tens of the 2-digit value below of those from the 3-digit ones. We encourage you to use vertical orientated problems until you get a solid grasp of this skill.

Take for example finding the difference between 231 and 26. Once we line it up, we subtract each place value individually starting at the far right. At the ones place we are subtracting 1 by 6 which does not work out. In these situations, you need to focus on the numbers you need to borrow. Borrowing or regrouping is taking a quantity from a higher place value and dropping it a place value. In the case of these types of problems we may take a value from the hundreds and drop it to the tens, or we may take a tens value and drop it to the ones.

For instance, we needed to borrow from tens place (3), since one is less than 6. We drop that tens value to the ones plus to elevate the 1 to an 11. Now we can easily proceed through the problem. We are left with a difference of 205. Keep practicing and the kids will get the hang of it.

If you are having trouble with these types of problems, you will find that working with place value blocks can be very helpful. They can help you visually understand how these exchanges take place. Another quick technique is to use the expanded form of the number. Expanded form is where we separate all of the place values. This can allow you to see gaps that are present. For example, we could have processed the problem we just worked on as:

  200 + 30 + 1
-           20 + 6
