Read the graph to find the smallest number of pony rides an individual child had.

Well, this picture graph shows information or what we call data about the pony rides that have been had by some children. And each picture is a symbol for that data. We can see that four individual children’s pony rides are shown and their names are written along the bottom of the graph.

We’ve got Matthew, Amelia, Olivia, and Liam. And each child has a column of symbols going upwards from their name. And we can see from the side of the graph that these represent the number of pony rides that each child has had. So the more symbols there are in a column, the more rides that someone has had.

But what is one symbol worth? This is really important because sometimes this symbol can represent more than one thing on a picture graph. We need to find the key which tells us that one picture of a horse or one symbol is equal to one pony ride. So all we have to do is to count the symbols to see how many rides each person has had.

We’ll start with Matthew: one, two, three, four. Matthew has had four pony rides. What about Amelia? One, two, three. Amelia has had three pony rides and Olivia, one, two, three, four, five, six. And we can see from the graph that Liam’s symbols are the same height as Olivia’s. So we don’t need to count them. He must have had six rides too.

Amelia’s column of symbols is the shortest column on the picture graph. And so the smallest number of pony rides that an individual child had are Amelia’s three pony rides.
