Double Digit Addition in the Primary Classroom

It is amazing to me how my little ones come to me only being able to add two small single digit numbers together and then after a few months can add (and subtract) with double digits.
During math, I try to incorporate as many movement activities and manipulatives that I can.  I will share a few of these with you.

First, here are a few instructional videos that you may want to use in your classroom.





If you have BrainPop, there are also a few videos in BrainPop Jr. that will be helpful.
Next the manipulatives I use (you probably already have), but can be checked out by clicking on the pictures below.

Now you probably want to know what I do with these mainpulatives.  First, I love using math stations or centers.  It allows me to reteach concepts or work with students that have skill gaps that need to be brought up to speed.  While I am doing this, the other students are interacting with these manipulatives, playing games, doing hands on work, or some form of technology.  More on math stations later.  As you can see below, I have a lot going on in my room during station time.  My room is pretty much always a mess except for 8am and 2:45 (when we arrive and dismiss).

The students below are simply using 1 dice in dice (but you could use 2 dice) to create  2 digit number.  They will roll the dice twice to make two different two digit numbers.  They will add the two numbers they created together.  I just give them a blank sheet of paper, one dice in dice, and ask them to do this 10 times.  I check their work (or have a partner check their work) when finished.  




The girl below is working with center strips.  These strips contain double digit addition problems.  The student answers the problem, records answer, and then scans the QR code to check answer.  A version is included without QR codes as well.
 You can grab this center strip station by clicking here or on the picture below.

The students below are working with my interactive Printables.  They are playing a game, cut and pasting, and solving problems.


  
During station work, my kids can choose to sit anywhere in the room they would like.  Often times, they are working in partners or groups, and need to sit with them.  However, when doing printables or independent practice, I don't care where they sit (except at my small group area).

You can pick up the Printables pictured above by clicking here or on the picture below.
Another manipulative I like to use is dominoes.  They can be used for a variety of educational math skills.  One way I use them for double digit addition is similar to war.  Students select a partner, grab a blank sheet of paper, and sit by the dominoes.  They each take 2 dominoes (this is why double 9 dominoes are great for this activity).  With each domino they create a two digit number.  For example if on one domino there are 3 dots on one side and 8 on the other, they can make the number 38 or 83.  They will do this with both dominoes they have, write the number, and add the two numbers together.  The player with the highest sum gets to keep all 4 dominoes and create a pile.  Play continues for ten round and the player with the most dominoes at the end of the ten rounds wins the war (or game).




My new favorite station is my Math Card Sprint Stations.  It combines math problems (task cards) with exercise and brain breaks.  You will need access to a QR code reader for this activity.  You can place the task cards around the room (I suggest multiple copies of each task card)  for whole group, use during station time, or as a whole class in small groups with each group getting a copy of the task cards.  I have done it all three ways.  Each way works well, so it is up to you.  In the pictures below, I am doing it during station time and this group just happens to be working in the hallway (good thing we didn't have a fire drill).

Each student playing will start with the task card that says START.  They will solve the problem on the task card.  After solving the problem (there is a recording sheet), they will scan the code on the card.  It will tell them the answer (Self-Checking!!) and what card to go to next.  The cards are not numbered (but lettered) and not in any particular order.   They will continue solving problems and going to the next card the QR reader tells them.  The catch..the QR reader might tell them to go to a detour card.  On these cards, there are actually activities (exercises) for them to do.  After doing the exercises, they will scan the QR code and proceed. 
This is a fun and engaging way to keep students on task.  It will take about 20 to 30 minutes to complete a group of task cards by the time the brain breaks are figured in.  My kids love doing them.





You can check out my Math Task Card Sprints, you can click here or on the picture below.

Finally, my newest creation is practicing math word problems.  We work on highlighting the key words, writing our own, and solving word problems.  I turn this into a game by creating word problem task cards along with a BINGO game board for answers.  I display the word problem card under the document camera, read it, and the kids solve it and mark the BINGO square of the answer.  I give them a dry erase board and Expo marker to use to solve their problems, but you could also use just a piece of blank paper.

The task card set has 24 word problem task cards and includes 25 different BINGO boards (each student will get a different board).

Finally, if you are a Digital Classroom and use Google Classroom, Google Slides, or other platforms to push digital work out to your students, I have created a Bundle with the above Bingo Game and Digital Word Problem Task Cards (or you can buy the word problem task cards separate by clicking here).  
My kids loving doing their work on Google Classroom.  It is their new favorite thing to do.  We rarely do worksheets, but lots of interactive, digital activities.  Click on the picture below to preview the Bundle.

Do you have any ideas to share?  What activities do you do for double digit addition?
Have a great day!
God Bless,
