Take away counters to find the missing number. Six subtract three equals what.

In this question, we need to take away or subtract to find the answer. And this symbol in our number sentence shows us this. It’s the subtraction symbol. It shows us that we need to find three less than six. In other words, we need to start with six and take away three from it. Now we could try to find the answer in our heads or maybe draw a little sketch to help. But in this question, we’re told to take away counters to find the missing number. And we’re given this line of counters. Now without counting the counters, do you think you know how many there are?

We said that the first number in our subtraction is six. This is the number we begin with. So do you think it might make sense if we had six counters? Let’s see. One, two, three, four, five, six. So, we’ve got our six counters to begin with, and now we need to take away three of them. Now, before we do this on the screen, let’s really put your brains at work. Without drawing anything or writing anything, I want you to look at these six counters and I want you to imagine taking away three of them. Can you see how many there are going to be left? See if you can predict what the answer is going to be.

With each counter that we take away, we could cross them through. So, we need to take away one, two, three. And this leaves us with one, two, three. Six take away three equal three. We know that if we add three and another three together, we get six. So just like in this subtraction, if we start with six and then we take away three, we’ll be left with three. We’ve taken away counters to help find the missing number. Six subtract three equals three.
