Lesson 1: Picture graphs# Picture graphs

A picture graph, or pictograph, is a graph used to display information that uses images or symbols to represent data. For example, a picture graph displaying the amount of points scored by 5 basketball players could use the image of a basketball to represent 2 points and then display a basketball over each player's name for every 2 points she scored.

- What is a corral?(15 votes)
- I didn't know either so I looked in the dictionary. Here's what I found:

A corral is an area surrounded by a fence for keeping horses or cattle in, especially in North America.(3 votes)

- why do we need math(7 votes)
- it is useful in every day life.(5 votes)

- Picture Graphs and Bar Graphs represent data the same. Right? So why are we taught both of them in the Early Math curriculum of Khan Academy?(3 votes)
- They present two different ways of looking at similar problems.(4 votes)

- what means the mouse in the squar.(2 votes)
- It's the "legend" letting you know what one picture represents. He explains it at1:36. It says one, but there will be math problems that come up later that show a picture is the same as two cats or three cars. If each picture represented TWO mice, there would then be 8 mice in the house and 12 mice in the barn, and so on.(5 votes)

- At0:50they said to count the mice in the barn. How much mice is the symbol worth?(3 votes)
- In the top right of the video, there is a key that says 1 mouse symbol corresponds to 1 mouse in real life.(2 votes)

- what is a pasture?(1 vote)
- A pasture is a land covered with grass where cattle graze on. It's like an open field with grass.(6 votes)

## Video transcript

- [Voiceover] What we have
here is a picture graph, and the reason why it's
called a picture graph is because it uses pictures
to give us information. In this case, it uses
the picture of a mouse and it tells us that one of
these little mouse pictures means one mouse, it equals one mouse. So what is this picture graph telling us? Well, the title says "Mice on Farm," so this tells us how many mice are in the different places in a farm, and you can see here the different places where we might find mice. We could find mice in
the house, in the barn, in the pasture, or the corral. And then these, I guess
you could say these stacks of these mouse pictures tell us how many mice there are
in each of those places. So, for example, in the house, we see, well this, this they tell
us, that's one mouse, this is one plus one plus
one plus one, or four mice. Four mice in the house. That's four right over
there, write that over there. Four mice in the house. How many in the barn? Well, same idea, one, two,
let me use a different color, one, two, three, four, five, six, so there are six mice,
six mice, in the barn. So there's six mice in the barn, let me just write that down. So six mice in the barn,
what about the pasture? Well, we see that
there's three mice there, that's 'cause each of these
pictures is one mouse. The person who made the
picture graph could've made each of those pictures a
different number of mice, but here each one is one mouse, so there's three in the pasture. Three in the pasture. And then, finally, move over a little bit, and then finally there
are two in the corral. Two in the corral. So if someone asked you, "How many total mice
are there on this farm?" Well, you would add all of these up. You would say four plus six is 10, plus three is 13, plus 2 is 15. 15 total mice on the farm. So once again, picture graph,
just a way to show data, to show information. This tells us how many mice
are in each part of the farm. If someone said, "How
many mice in the barn?" you say, okay, well, you
know, there's six mice. If someone says, "How many mice are "in the pasture and the corral combined?" Well, that's gonna be
the three in the pasture plus the two in the corral, or five. They said, "How many
mice in the whole farm?" and if these are all the
places where the mice could be, well, it's gonna be the four
plus six plus three plus two, or 15, and we're done.
