This diagram shows the number of animals at a farm. a) How many sheep and cows are there altogether? b) There are more ducks than horses. How many more are there?

We know the graph shows the number of animals at a farm. There are sheep, horses, cows, and duck. The number of animals starts at zero. And the scale of the line which tells us the number of each animal goes up in twos, zero, two, four, six, eight. The numbers in between are one, three, five, and seven. Part a or the first part of the question asks us, how many sheep and cows there are altogether? Let’s start by counting how many sheep there are. We could see that the sheep reach number six. So there are six sheep.

Now, let’s see how many cows there are. We can see there’re four cows. So how many sheep and cows are there altogether? What is six and four more? Six, seven, eight, nine, 10. Six plus four equals 10. So there are 10 sheep and cows altogether. Part b of the question tells us there are more ducks than horses. Let’s see how many ducks there are. Ducks reach up to this line. And if we follow the line across to our scale, we can see that there are seven ducks. And we can do the same with the horses which reach out to this line here. And if we draw our arrow to the scale, we can see that there are three horses.

Seven is more than three. How much more? How many more ducks are there than horses? Let’s find the difference between three and seven by counting forward from three until seven on our number line, one, two, three, four. There are four more ducks than horses. In the first part of the question, we had to calculate the total number of sheep and cows. We did this by adding together the six sheep and the four cows to give us a total of 10. To answer part b of the question, we found the difference between the number of ducks and horses. There were seven ducks and three horses which gave us a difference of four.
