Double-Digit Addition Virtual Activities

Blog post about teaching 2-Digit Addition Virtually, Digit Addition Lessons and Activities

Are you still teaching virtually? Or, are you looking for easy ways to incorporate digital activities into your math instruction? If so, you’ve come to the right place! In today’s blog post, I will be describing several different ways to teach Double-Digit Addition with virtual activities and instruction.

Common Core Standards for Double-Digit Addition will be found in first and second grade. The specific skills needed for each grade level are listed below.

  • First Grade: 1.NBT.C.4- Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
  • Second Grade: 2.NBT.B.5- Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Plan Out to Teach One Strategy at a Time

With double-digit addition, you’re going to want to start with a list of strategies. Create a list of addition strategies you’d like to teach and then plan them across your timeline. I suggest starting with base-ten blocks. This will help strengthen students understanding of base-ten values before scaffolding them into combing large numbers.

Next, introduce expanded form, also called the “break apart” method. Then, if you intend to show students the give and take method or an open number line, you can after that. Make sure your students have a strong understanding of the base-ten concepts and at least one of the double-digit addition strategies BEFORE showing them the standard algorithm. With all math standards, it is extremely important for your students to understand the concept before teaching them the skill, and especially before teaching them a “trick” or a “shortcut.”

A tip: Be sure to include time in your lesson planning to teach adding with and without regrouping explicitly as two separate lessons. Students will need focused practice with each strategy in order to gain full mastery.

Use Zoom or Meet for Direct Instruction

Now, you’ve mapped out your timeline. It is time to teach your double-digit addition strategy lessons. For virtual instruction, you could pre-record your lessons or teach them live.

For pre-recorded lessons, I would suggest posting them in a space that can be revisted. Your students may need to watch the lesson more than once if they aren’t getting live feedback and redirection.

You can also teach these lessons live, which is my suggestion. Whether you are using Zoom or Meet (or your school’s chosen platform), you can teach your lesson as if your students are there with you. Stand in front of your whiteboard or share a digital whiteboard so that your students can track your steps. *Make sure they are following along by having them write down the problems with you. And, allow time for questions so that you can correct misconceptions on the spot.

Using WhiteBoard.fi for Double-Digital Addition

Whiteboard.fi for individual virtual student whiteboards

Coincidentally, there is a free, online tool called Whiteboard.fi that acts like a personal whiteboard for each student. All you have to do is share the link and your students can practice their double-digit addition on a digital whiteboard.

In the example above, you can see that students can draw out their strategies in order to complete the double-digit addition. This will allow you to see their work and assess who is understanding the concepts and who needs extra instruction. After seeing all of the student responses, you can easily “Clear all whiteboards” and pose another question or move forward with your next task.

Using Pre-Made Google Slides or Seesaw Virtual Activities

Students will need skill practice for each strategy, as well. An easy way to implement skill practice into your virtual instruction is to use pre-made digital skill activities. The virtual skill activities in the example above are included in this set of digital double-digit addition activities. They are premade in Google Slides and Seesaw.

The activities in this set cover each of the double-digit addition strategies previously mentioned, (base-ten, give and take, break-apart, open number line, standard algorithm). Students will be practicing their double-digit addition skills on Google Slides or Seesaw, manipulating each page with their mouse and keyboard. The pages can be assigned individually or you can share the entire document with your students and assign 1-2 pages each day for practice.

Ask Students to Verbally Walk Through Their Math on Flipgrid

Another virtual tool for students is Flipgrid. Flipgrid is a free video discussion platform that allows you to create a forum for specific activities/discussions/ideas/etc. So, for use in your math class, students could create a Flipgrid video walking you through how they solved a double-digit addition problem.

As you are teaching each of the double-digit addition strategies, you could have students use Flipgrid as their exit slip. So, for each strategy, students could use paper/pencil, whiteboard, or even whiteboard.fi to solve a problem. Then, they can create a Flipgrid video walking through their math steps, showing their calculations, the process, and the result.

You can easily assess your students understanding by watching their Flipgrid videos! Now, you know who needs what type of instruction moving forward!

Gamify Their Math with IXL

IXL addition game-like virtual activities

Previously, I have mentioned using IXL.com for skill practice. This site is excellent for standard-specific skill practice. Not only are students going to be prompted with problems that are specific to your strategy, but they will also be getting live feedback and explanations for misconceptions. IXL has several activities for base-ten and standard aglorithn. So, students will be able to practice their double-digit addition as much as they need!
