About this video
This video answers questions using picture graphs where each picture stands for more than one thing. It compares sunny days by counting suns (each worth 6 days), combines mice from two days (each picture worth 2 mice), and finds how much less rain one town had (each raindrop worth 6 millimeters).
You'll be able to
- use a picture graph key to find the real amount for each row.
- compare rows by comparing the number of pictures.
- combine or subtract amounts shown in a picture graph.
Key words
- picture graph
- A graph that uses pictures to show amounts.
- key
- Tells how many each picture stands for, like one sun = 6 sunny days.
- fewer
- A smaller number of something.
- combined
- Put together or added.
Transcript
- Let's tackle some exercise with picture graphs, and once again, I'm using the Khan Academy exercise to do this. It says, which towns had fewer sunny days than Sparkle City in June? All right, so, if we look at the picture graph down here, each picture of a sun represents six sunny days.
We want to say which towns had fewer ... what did they say? Fewer sunny days in Sparkle City in June. Sparkle City is this one right over here. Sparkle City had, let's see, we have one, two, three, four, five pictures of a sun. Each of those represents six sunny days.
Five times six ... Sparkle City had 30 sunny days in June. Which of these had fewer than 30 sunny days? Well, you can just look at the picture graph itself, and all of Sunville, Shinny Town, and Star Village, they don't have as many of these pictures of the sun.
They all had fewer sunny days. We actually don't even have to calculate how many sunny days each of these represent. Although, if you cared, this would be four times six, this would be 24. This would be two times six or 12. This would be three times six or 18 sunny days in June.
All three of them, Sunville, Shinny Town, and Star Village. Sunville, Shinny Town, and Star Village all had fewer sunny days than Sparkle City in June. Let's keep going. Let's do a couple more of these. The graph shows how many mice a farmer found in here field each day for five days.
Which day did the farmer find the same amount of mice as on Wednesday and Thursday combined? All right, let's look at this. Each picture of a mouse represents two mice. See, on Wednesday and Thursday combined, there's two ways to think about his. On Wednesday and Thursday combined, I have one picture of a mouse, and then two more pictures of mice.
That's a total of three pictures of mice. What other day do I have three pictures of mice? Well, Tuesday I have three pictures of mice. I could just pick Tuesday. Another way to think it is on Wednesday, the actual number of mice that were observed, one picture means two mice.
Two mice on Wednesday, four mice on Thursday, because I have two pictures each of them represent two mice. Two on Wednesday, four on Thursday, so six total. You see on Tuesday we have six mice were observed. Once again, each of these pictures represent two. Two, four, six.
There you go. All right, let's keep going. Funland had blank millimeters less rainfall than Happyville in August. This right over here, this is Funland, this is Happyville, and each little raindrop picture represents six millimeters. Funville has two raindrop pictures, Happyville has four raindrops pictures.
Funland had two less raindrop pictures. I had two less of these raindrops. Two less raindrops would be two times six, it would be 12. 12 millimeters less rainfall than Happyville. Another way you could have thought about it Funland had 12 millimeters of rainfall in August.
Each of these six then 12. Each of these represent six millimeters. Happyville had six, 12, 18, 24 millimeters. 12 millimeters verses 24 millimeters. Well, Funland's going to have 12 millimeters less. 12 millimeters is 12 less than 24 millimeters.
