Ordering up to Six Objects by Length
00:00:06.910 --> 00:00:15.410
In this video, we will learn how to compare the lengths of objects and order them from longest to shortest or shortest to longest.
00:00:17.260 --> 00:00:28.420
If we look closely and compare the lengths, we can see that the snake at the top is the longest and the snake at the bottom is the shortest.
00:00:30.370 --> 00:00:34.960
Now that weβve compared the lengths of the snakes, we can order the objects.
00:00:35.170 --> 00:00:39.000
We can order the snakes from shortest to longest.
00:00:40.450 --> 00:00:51.360
The shortest snake would go at the end of the line which is marked the shortest, and the longest snake goes at the end of the line marked longest.
00:00:52.930 --> 00:00:57.880
We could also order the snakes from longest to shortest.
00:01:00.060 --> 00:01:06.720
Now letβs practice ordering some objects from longest to shortest and shortest to longest.
00:01:09.080 --> 00:01:12.470
Order the lines from longest to shortest.
00:01:14.010 --> 00:01:19.120
The question tells us we need to order the lines from the longest to the shortest.
00:01:21.200 --> 00:01:23.080
We need to find the longest line.
00:01:23.610 --> 00:01:27.520
To do this, we need to compare the lengths of the lines.
00:01:29.260 --> 00:01:36.970
Now that weβve compared the lengths using these dotted lines, we can see that line π is the longest.
00:01:38.460 --> 00:01:45.100
Now we need to compare the lengths of lines π, π, π, and π to find the longest.
00:01:46.610 --> 00:01:49.420
Line π is the longest of these lines.
00:01:50.810 --> 00:01:54.120
Now we can compare the lengths of lines π, π, and π.
00:01:55.870 --> 00:01:58.140
π is the longest of these lines.
00:01:59.370 --> 00:02:03.400
Finally, we just need to compare the lengths of lines π and π.
00:02:05.110 --> 00:02:07.680
π is the longest of these two lines.
00:02:09.310 --> 00:02:13.810
That leaves us with line π, which means that line π is the shortest.
00:02:15.740 --> 00:02:22.360
The order of the lines from longest to shortest is π, π, π, π, π.
00:02:24.020 --> 00:02:29.670
Letβs practice another example which asks us to order lines according to their lengths.
00:02:33.790 --> 00:02:37.190
Order the lines from shortest to longest.
00:02:38.720 --> 00:02:43.730
In this question, we have to order the lines from shortest to longest.
00:02:44.160 --> 00:02:46.760
To find the shortest, we need to compare the lengths.
00:02:47.860 --> 00:02:52.400
Now itβs easy to see that line π is the shortest.
00:02:53.950 --> 00:02:56.800
Now we need to compare lines π, π, π, and π.
00:02:56.840 --> 00:02:58.580
Which of these is the shortest?
00:03:00.040 --> 00:03:01.140
Itβs line π.
00:03:02.220 --> 00:03:07.130
Now we can compare the lengths of the remaining lines, lines π, π, and π.
00:03:08.940 --> 00:03:10.500
π is the shortest.
00:03:11.710 --> 00:03:15.240
Now we just have two lines left to compare, lines π and π.
00:03:15.430 --> 00:03:17.110
Which of these is the shortest?
00:03:18.530 --> 00:03:19.560
Itβs line π.
00:03:20.840 --> 00:03:24.520
This just leaves us with line π, which is the longest.
00:03:25.500 --> 00:03:31.980
So the order of the lines from shortest to longest is π, π, π, π, π.
00:03:33.420 --> 00:03:42.670
In this video, weβve learnt how to compare the lengths of objects and order them according to length from shortest to longest or longest to shortest.
