After going through the theories, it’s time to practice. Get ready, little champs. The following sections will provide you with some fun activities to find missing addends anchor chart.

Go through the details of each activity and understand the images carefully. So, let’s start our journey with a fresh mind.

Activity 1: Hop and Hop

Let’s start with a simple task of this missing addend anchor chart. You can see the problem in the image below. Your first job is to find the required information and the value to be found.

To find the missing addend, you can use a number line. First, we are talking about the number line. Put the two values in the number line that you previously found in the question. Now, what to do? Here comes your analysis skill. You see there is some gap between the two numbers.

Start to hop from the first number to the second one. Remember how many points you have earned. When you have exactly come to the second number, stop hopping.

Activity 2: Do the Part-Part Whole

The second way to find missing addend is to use a part-part whole box. This type of box is very useful for finding missing addend-related problems. You have to put the whole or the total number in the lower part of the box.

Then, you will notice two extra parts on the top side of the box. Place the first part, the first number, or the first number or first addend that you will find in your problem. Now the other part is empty.

What to do? As both the upper parts come together to make the lower value just subtract the given upper part from the total or the whole and find your missing addend.

Activity 3: Remove Counters

This fun activity is also useful to find the missing addend. Thinking how? Ok, let us explain first. Like the previous two activities, you can see a problem in the following image. Now, identify the total and the giving addend from the problem.

Then, draw an exact amount of your favorite shape equal to the whole or total. After that, give a cross sign on the number of shapes equal to the given addend. Seems easy, right? Finally, count the number of counters without any cross marks and tell me what you know!

This is your missing addend. Now, surprise your teacher by telling him the answer.

Activity 4: Climb the Mountain

Let’s make a number mountain. How? From your given problem, take the bigger number and place it on the mountaintop. It is clear that the top is built by adding the bottom values. So, the next task is to place the smaller of the two numbers from the question and put it on the bottom-right side of the mountain.

It’s time to count. Start from the lower-left side of the mountain. See, there is no value here, and you have to find it. Remember the number from the bottom-right? Start to count after that number and put a dot on the way from the missing addend’s space to the top of the mountain. Keep putting dots on the page until you reach the top and your counting is finished.

Now count the number of draws that you have to make to reach the top. Hurray!!! Show the answer and earn a good performer badge from your teacher.

Activity 5: Use Ten Frames

Another strategy to find your missing addend is the use of ten frames. This is a rectangular-shaped frame where ten spaces are built. You can use this tool to practice your number problems that are between 1 to 10.

So what’s your role in using this tool? Let me explain. First of all, draw ten frames like the following image. Under the image, write the total or whole value. Then mark the room that is equal to the whole by counting from the left.

This is your destination. Still didn’t get it, right? Okay, no problem. Take a colored pen and start to color the spaces in the frame. How many? Equal to the number that is given aside from the total in your problem.

After all of these, you will see some white spaces or gaps left between the dots and the mark that was made in the first place. Count the number of white spaces and taste victory.

Activity 6: Gather Some Blocks

Enough theory for today. Let’s take a break. What to do? The missing addends aren’t allowing you to take the desired break. Fear not. We are coming up with another plan to aid you.

Take your paper and some colored pencils. Like the previous instructions identify the given numbers. In your practice sheet, make a pillar of blocks that match the whole or total of your problem. Color the blocks after gathering. Then, notice the smaller number, and build the same number of blocks on the right side of the previous one.

Use another color to differentiate it from the other column. Count how many blocks are missing to make the whole column look like the previous one. The gap is our required missing addend.
