Common sense tells you that a pictograph must be some kind of....picture. Yes! A pictograph is basically a way to represent data with pictures that relate to the data. Let's look at this word problem that asks to interpret a pictograph. Created by Sal Khan and Monterey Institute for Technology and Education.

• What do you do when there's half of an object?
• When there's only half an object, it means that only half the "units" are being represented. For example, in this video, half a blood drop would mean 4 people because a whole drop means 8.
• How does "●" symbolise multiplication?
• The Reason Why The Dot Is A Sign Of Multiplication( Simplified Reason) is to avoid confusion between variables.. For example
9 x (X=30)
In This Problem , The problem solvers may get confused with the two X's , so to fix this situation mathematicians have resolved to using a dot as a sign of multiplication . Your Welcome :D
• I know this is not that related to the video but shouldn't there be more o neg because o o neg the common blood type sorry if I have bad grammar I am a fifth grader and I really doubt that no one an will look back at this thing because it is old and I am older do that doesn't matter
• Hi. O is the most common blood type. But most of those are O positive. O negative is rarer. Only about 7 percent of the population have O negative.
• Why do we divide by 2 when there is half an object ?
• Half of a picture tells us that the picture represents half of the value of the regular sized picture. In the video example, if there was half a drop of blood it would represent 4 people, we get this by dividing the regular value of 8 people per drop of blood by 2. If there ever is a quarter or a third of a picture you would also divide to find out what value they were as but you would divide by 4 and 3 to find out the value.
• what to do if a question said one drip = 3 people but there is half a drip
• Hi, you can divide the 3 by 2 which gives 1.5 in this case
• why is this so easy
• idk, maybe you're good at probability
• How are pictographs used in real life?
• What is the age I am supposed to be doing this course at
• i mean, i'm almost a junior in high school and we just started this unit, but I also remember doing this in 6th grade as well.
