There are six rabbits and four of them do not have carrots. How many rabbits have carrots? What plus four equals six.

We can see that the missing number in the equation that we’re given in this problem isn’t at the end. Often we do have to find the total number if we’re adding two numbers together. But in this problem, we need to find one of the parts that we add together. Our missing number is the first number in the addition. What add four equals six. To help us find this missing number, let’s look at what the problem’s describing. To begin with, we’re told that there are six rabbits. Now, are these six rabbits part or the whole amount? Well, if we count them quickly, we can see that they are the whole amount, the total. There are six rabbits altogether.

So if we were drawing a part–whole model, we’d write the number six to represent the whole. And our whole line of six rabbits is split into two parts. We’ve got a group of rabbits that do have carrots and then another group of rabbits that do not have carrots. And we don’t need to count this second group because we’re told in the question four of the rabbits do not have carrots. So part of the whole amount is the number four. And we’re asked how many rabbits have carrots. In other words, what number goes together with four to make a total of six?

We could use counters to model the problem. We could use six counters to represent our six rabbits. Now, four of our rabbits do not have carrots. So perhaps we could use a different-colored counter, one, two, three, four. So if these pink counters represent the rabbits that do not have carrots, let’s count the white counters. These are the rabbits that do have carrots. We can see that there are one, two white counters. And of course, we could count the rabbits in the picture, one, two. The number two goes with the number four to make a total of six. Six is equal to two plus four. And so if there are six rabbits and four of them do not have carrots, the number of rabbits that do have carrots is two.
