Hello, everyone! Today, we’re going to have a fun time learning subtraction with a little penguin. We’ll use a special trick called “counting back” to make subtraction easy and exciting!
Counting back is a way to subtract numbers by counting backwards. Let’s say we have the problem 7 minus 3. We start by saying the number 7 out loud. Then, we count backwards until we reach the number 3. Use your fingers to help you keep track!
For 7 minus 3, say “seven” and then count backwards: six, five, four, three. How many fingers are you holding up? One, two, three, four! So, 7 minus 3 equals 4. Great job!
Now, let’s help the little penguin find his way to his mother. We need to connect all the ice floes where the answer is 6. Let’s start with the problem 13 minus 7.
Count backwards from 13: twelve, eleven, ten, nine, eight, seven. How many fingers? One, two, three, four, five, six! So, 13 minus 7 equals 6. Draw a line to connect them!
Next, let’s try 10 minus 4. Count backwards: nine, eight, seven, six, five, four. Six fingers again! Connect 10 minus 4 to the path.
Now, let’s see if 12 minus 6 equals 6. Count backwards: eleven, ten, nine, eight, seven, six. Yes, it does! Draw a line to connect them.
Try 16 minus 10: fifteen, fourteen, thirteen, twelve, eleven, ten. Six fingers! Connect 16 minus 10 to the path.
For 19 minus 13, count backwards: eighteen, seventeen, sixteen, fifteen, fourteen, thirteen. Six fingers again! Draw a line to connect them.
Let’s check 11 minus 5: ten, nine, eight, seven, six. Six fingers! Connect 11 minus 5 to the path.
Try 17 minus 11: sixteen, fifteen, fourteen, thirteen, twelve, eleven. Six fingers! Connect 17 minus 11 to the path.
Finally, let’s do 15 minus 9: fourteen, thirteen, twelve, eleven, ten, nine. Six fingers! Connect 15 minus 9 to the path.
We’ve connected all the ice floes with a difference of 6. You did an amazing job using the counting back strategy!
When subtracting, say the first number but don’t count it. Touch your chin to remember: seven. Then count backwards to the other number using your fingers: seven, six, five, four, three. Count your fingers: one, two, three, four. Seven minus three is four!
Great job, everyone! Keep practicing, and you’ll be a subtraction superstar. See you next time!

Penguin Subtraction Adventure: Create a simple board game using paper and markers. Draw a path with numbered spaces from 1 to 20. Use small toy penguins or coins as game pieces. Roll a dice and move your penguin forward. When you land on a space, subtract the number on the space from 20 using the counting back method. If you get the correct answer, you can stay on the space. If not, move back two spaces. This will help you practice subtraction while having fun!
Subtraction Scavenger Hunt: Go on a scavenger hunt around your house or classroom. Find objects in groups, like pencils, blocks, or toys. Pick a group of objects, count how many there are, and then remove some. Use the counting back method to figure out how many are left. For example, if you have 10 blocks and take away 3, count back from 10 to find out how many are left. Share your findings with a friend or family member!
Subtraction Story Time: Create a short story about a penguin who loves to collect shiny pebbles. Each day, the penguin finds a certain number of pebbles but loses some on the way home. Write down how many pebbles the penguin starts with and how many are lost. Use the counting back method to find out how many pebbles the penguin has left at the end of the day. Illustrate your story with drawings of the penguin and pebbles!

Welcome to Kids Academy! Hello everyone! Let’s open the worksheet. Don’t forget to like this video and subscribe to our channel. You can find the link to this app in the comments below. Today, we’re going to be working on a fun subtraction worksheet. I’d like to go over a strategy I call “counting back” to make this worksheet a little bit easier.
Let’s review this strategy, and then we’ll try the worksheet together. For my strategy, we’re going to be counting backwards. So for a problem like 7 minus 3, we’re going to say the number 7 out loud. I like to touch my chin when I say the number to know that I’m not counting it in my subtraction problem.
Let’s try it together: seven minus three. We’re going to say the number seven out loud and then count backwards until we get to three. We’ll use our fingers to help us keep track of how many times we’re counting. However many fingers we’re holding up will be the correct answer.
Let’s try it together: seven, six, five, four, three. Okay, I landed on my number three. How many fingers am I holding up? One, two, three, four. So, seven minus three equals four.
Let’s use this strategy of counting back to answer the questions on this worksheet. Let’s read the directions and get started right away.
Subtract with the little penguin! Help the little penguin find his path to his mother by drawing a line to connect all the ice floes where the number six is the total.
Okay, I think we should start where it says “start.” Our first problem is 13 minus 7. Let’s use our counting back strategy again: 13… remember, don’t count 13, 12, 11, 10, 9, 8, 7. Okay, I landed on my target number of seven. Am I holding up six fingers? One, two, three, four, five, six. I am!
So this is a great place to start. Where are we going to move from here? I say we try all the numbers that are connected to this to see if six is the total. If it is, we’ll draw a line, and if it’s not, we’ll know we have to try something else.
So let’s try 10 minus 4, counting backwards again: ten, nine, eight, seven, six, five, four. Do I have up six fingers? Yes, I do! So let’s draw a line from 13 minus 7 to 10 minus 4. Good start!
Now from 10 minus 4, I have two choices: I can draw a line to 12 minus 6 or I can draw a line to 16 minus 8. Let’s try 12 minus 6 first: 12, 11, 10, 9, 8, 7, 6. I landed on six, and I have six fingers up. Counting backwards is a good strategy to make the subtraction go a lot faster, so let’s draw a line from 10 minus 4 to 12 minus 6.
Again, I have two choices: I can draw a line to 16 minus 10 or 17 minus 5. Let’s try 17 minus 5 since we’re working horizontally: 17, 16, 15, 14, 13, 12, 11, 10. Already, I see way more than six fingers up. I don’t think that 17 minus 5 is the right answer.
Let’s try 16 minus 10: 16, 15, 14, 13, 12, 11, 10. Six fingers up! This must be the correct answer. Let’s draw a line to 16 minus 10.
Now for this problem, I have three different choices. I can draw a line to 16 minus 8, but I already know that’s not the right answer because I tried that for another problem. So I’m left with 12 minus 4 or 19 minus 13.
Let’s try 19 minus 13: 19, 18, 17, 16, 15, 14, 13. Does nineteen minus thirteen equal six? I think so! I have six fingers up. Let’s draw a line to nineteen minus thirteen.
Another place where I have three choices: I can draw a line to 11 minus 5, a line to 14 minus 7, or a line to 16 minus 9. Which one do you think is going to equal six?
Well, I know 16 minus 9 probably isn’t the right answer; it’s going to have too big of a difference. What about 11 minus 5? Let’s try that one: 11, 10, 9, 8, 7, 6. Okay, I got to five, and I have six fingers up. Eleven minus five is definitely six, so let’s draw a line to eleven minus five.
Again, I have quite a few choices here. Can you do 13 minus 3 in your head? Because if you can, you would know that 13 minus 3 is just 10, because 3 minus 3 is 0. So I don’t think 13 minus 3 is the right answer. Let’s try 17 minus 11.
Counting backwards again: 17, 16, 15, 14, 13, 12, 11. Six fingers up! Seventeen minus eleven is six. Nice job!
So again, we have a few choices. We can draw to 4, we could draw a line to 14 minus 9, or we could draw a line to 16 minus 9, or we could draw a line to 15 minus 9. Which one do you think is going to equal six?
Well, I think 14 minus 9, that’s not going to be enough; those numbers are too close together. 16 minus 9, we already know those two numbers are too far away, so let’s try 15 minus 9. Let’s count backwards from 15 to 9: fifteen, fourteen, thirteen, twelve, eleven, ten, nine. Six fingers again! Excellent job! Let’s draw a line to fifteen minus nine because fifteen minus nine equals six.
Now there’s only one more place to draw a line to. Let’s check our work just to be sure. Let’s count backwards from 14 to 8: 14, 13, 12, 11, 10, 9, 8. Six fingers! We’ve now drawn a line to all the subtraction questions that have a difference of six.
Great job using the counting back strategy, boys and girls! Remember, when you’re subtracting, for example, like 7 minus 3 in our examples, say the number but don’t count it. Touch your chin just to make sure: seven. Then count backwards to the other number using your fingers to help: seven, six, five, four, three. Count the fingers: one, two, three, four. Seven minus three is four.
Great job, boys and girls, using the counting back strategy with the penguin! We’ll see you next time!
