Addition with Regrouping Strategies

I am a huge advocate for teaching students the WHY before the PROCEDURE when learning a new math concept.  I am a firm believer that teachers owe it to their students to teach them multiple ways to solve math problems.  We all learn concepts in different ways and math is no different.  With that said, this post is going to explain several different addition with regrouping strategies that you can teach your students so that they can better understand this concept.

Addition with regrouping is a very systematic concept for students to learn and without a solid understanding of place value, there’s no point in going any further with instruction.  It is essential that students are firm in their place value skills before moving forward with addition with regrouping.  Depending on where you teach, you may be required to teach 2-digit and 3-digit addition a bit differently.  So, I am providing you will a variety of strategies that you can try with your students.  If you see a strategy that you cannot use, keep scrolling.  I promise there will be something that you will find helpful.

Place Value Mats

Before I start my addition with regrouping unit, I spend a month teaching place value.  Students must be solid in their place value understanding to truly understand the WHAT and WHY of addition with regrouping.  The first day of teaching this skill, my students receive unifix cubes and they learn what regrouping looks like.  You can also use place value blocks but I like that unifix cubes can be pulled apart and pushed together.  We always start with a two-digit number on top and a one-digit number on the bottom.  Here’s how I teach it:

As I am going through this lesson, I have students who seem to be able to grasp the concept, come up and show the class how to do it all while explaining what they are doing.  When students explain their thinking and thought process, it is extremely powerful.

After a day or two of teaching this concept using the place value mat, I will have them move to paper and pencil solving but still provide them with their unifix cubes and place value mat to build and solve each problem.  Make sure to scoop up your FREE place value mat before going any further!

One tip is to give your students highlighters and have them go through their worksheet and highlight the ones place so that they have the visual reminder of where to start solving their math problems.

Be watchful of those who just want to take the two-digit number and count on.  Although this is a practical way to solve these problems, you must be also thinking about the concept that you are trying to teach them…regrouping.

Next, we move to two-digit numbers on top and bottom.  Of course, we go back to the math manipulatives to help them see and understand the process of regrouping.

We continue to highlight the ones place at this stage.  I want to make it a habit for my students to always start with the ones place first.  This concept is more complicated for them then we realize.  They are trained to read and write from left to right so starting them on the right side of the problem tends to cause some students to struggle.

As I stated at the top of this post, I am a firm believer in teaching students multiple ways to solve problems because you never know what will connect with them.  Here are a few more ways that I have shown my students how to solve addition with regrouping problems.

Post-it Note Method

Break It Up Method

Slice & Split Method

Once your students find a method or two that they feel comfortable using, it’s important to provide plenty of opportunities to practice!  Here are some resources that you can start using in your classroom today! (links below image)

    You did a great job presenting these strategies! I watched your presentation over my morning coffee and walked away with some great ideas. I've never used the highlighter strategy; love how visual that is and that it costs nothing to add to our classroom routines. Love your place value mat too! Thanks for sharing your hard work! 🙂

    Hi Angie, thank you for the great tips! You really make my day. I simply love how you use the manipulatives and make Maths so fun! The manipulative I use most are the unifix cubes but the post-it idea is simply awesome – so easy and so visual!

    I’m a kindergarten teacher and love these ideas. I know my kiddos are slowly getting regrouping but I definitely want to show them some of the cool
    Ideas to show place value when adding! 🙂

    I’m so glad that I found this! I remember using this in Kindergarten/First Grade and it helped my babies out so much!

    I am now in 3rd grade and was wondering if you have a place value mat for 3 digits?

    What strategy can you use if a student is adding 2 digit numbers in error. For example if they add 83+39 and get 1112 for the answer.

      Hi Kandace. I suggest taking out a place value mat (I have a free template on my website) and showing the student how to solve with hands on manipulatives. Hope that helps!
