Ordering up to Six Objects by
Length

In this video, we will learn how to
compare the lengths of objects and order them from longest to shortest or shortest
to longest. 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. Now that weβve compared the lengths
of the snakes, we can order the objects. We can order the snakes from
shortest to longest. 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. We could also order the snakes from
longest to shortest.

Now letβs practice ordering some
objects from longest to shortest and shortest to longest.

Order the lines from longest to
shortest. The question tells us we need to
order the lines from the longest to the shortest. We need to find the longest
line. To do this, we need to compare the
lengths of the lines. Now that weβve compared the lengths
using these dotted lines, we can see that line π is the longest. Now we need to compare the lengths
of lines π, π, π, and π to find the longest. Line π is the longest of these
lines. Now we can compare the lengths of
lines π, π, and π. π is the longest of these
lines. Finally, we just need to compare
the lengths of lines π and π. π is the longest of these two
lines. That leaves us with line π, which
means that line π is the shortest. The order of the lines from longest
to shortest is π, π, π, π, π.

Letβs practice another example
which asks us to order lines according to their lengths.

Order the lines from shortest to
longest. In this question, we have to order
the lines from shortest to longest. To find the shortest, we need to
compare the lengths. Now itβs easy to see that line π
is the shortest. Now we need to compare lines π,
π, π, and π. Which of these is the shortest? Itβs line π. Now we can compare the lengths of
the remaining lines, lines π, π, and π. π is the shortest. Now we just have two lines left to
compare, lines π and π. Which of these is the shortest? Itβs line π. This just leaves us with line π,
which is the longest. So the order of the lines from
shortest to longest is π, π, π, π, π.

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.
