00:00Hi kids! Today we will be learning about solid column graphs. So let's get started!
00:12Miss recorded the number of books read by students in her class and depicted it as a graph
00:22where symbol of one book represents five books. Now let's answer a few questions based on this graph.
00:37Now can you tell Bob read how many books? Let's count.
00:46There are two book symbols and one book stands for five books
00:56where symbol of one book represents five books. So 5 plus 5 or 5 times 2 equals to 10.
01:12So Bob read 10 books according to the graph.
01:18Can you tell Cheryl read how many books? Let's count.
01:25There are four book symbols and one book means five books.
01:335 plus 5 plus 5 plus 5 or 5 times 4 equals 20.
01:43So Cheryl read 20 books.
01:48Now can you tell Maurice read how many books? Let's count.
01:57There are three book symbols and one book means five books.
02:05So Maurice read 5 plus 5 plus 5 or 5 times 3 equals 15.
02:18That is Maurice read 15 books.
02:23Now who read the maximum number of books?
02:29There are five book symbols against the name of Kim which is most of all.
02:37So Kim read the maximum number of books also.
02:42One book stands for five books here.
02:47So Kim read 5 times 5 equals 25.
02:54That is 25 books.
02:58So Kim read 25 books which is the most of all.
03:05Now who read the least number of books?
03:10There is only one book symbol against the name of Raj which is the least of all.
03:19So Raj read the least number of books that is five books.
03:27Now how many students read more books than Maurice?
03:33Let's find it out.
03:36There are two columns where there are more book symbols than Maurice.
03:43So two students read more books than Maurice.
03:49Now can you tell who read more books than Cheryl?
03:55Let's find it out.
03:58There is one column where there are more book symbols than Cheryl.
04:06And that column belongs to Kim.
04:10So Kim read more books than Cheryl.
04:15Now who should be the winner of book reading competition?
04:21Yeah! Kim!
04:24As Kim read the maximum number of books.
04:28Good!
04:31Now let's take another example.
04:36Here is a graph showing the number of taxi drivers in different cities.
04:43And one taxi driver stands for 10 taxi drivers.
04:49Now let's answer a few questions.
04:55How many drivers are there in Boston?
05:00There are three driver symbols against Boston.
05:06Where one symbol says 10 drivers.
05:10So 10 plus 10 plus 10 or 10 times 3 equals 30.
05:21That is 30 drivers are there in Boston.
05:27Now how many drivers are there in Berlin?
05:34There are two driver symbols against Berlin.
05:40Where one symbol means 10 drivers.
05:45So 10 plus 10 or 10 times 2 equals 20.
05:53That is 20 drivers are there in Berlin.
05:59Now which city has least number of taxi drivers?
06:05There is only one driver symbols against Milton.
06:10So Milton has the least number of drivers.
06:15Now which city has maximum number of taxi drivers?
06:22There are four driver symbols against Lexington.
06:28So Lexington has the most or maximum number of drivers.
06:35Question 5.
06:38How many fewer drivers are there in Berlin than Lexington?
06:45Let's figure it out.
06:49There are two driver symbols against Berlin.
06:54And four driver symbols against Lexington.
07:00So 4 minus 2 equals 2.
07:06So there are two more driver symbols against Lexington.
07:12And we know one symbol stands for 10 drivers.
07:20So 2 times 10 equals 20.
07:24So 20 more drivers are there in Lexington than Berlin.
07:31Good!
07:33Wasn't it so interesting to find out facts from a graph?
07:40Now you may go ahead and take a quiz to learn more.
07:44Bye-bye!
