Comparing Groups of Objects: Less
In this video, we will learn how to
compare two groups of up to five objects to see which has less objects. These two jars of candies are
equal. Each jar contains the same number
of candies. The first jar has three candies,
and the second jar has three candies. But if we eat one of the candies
from the first jar, the amount of candies in each jar will not be the same
anymore. The first jar only has two candies
now. This Jar has less candies than the
second. The second jar has three
candies. It has more candies than the
In this video, we’re going to learn
different ways to find which group has less. Which jar has less teddy bears? We could use counters to help us
compare. Each time we count a teddy bear, we
could place a counter. The first jar has one, two, three
teddy bears. And the second jar has one,
two. Three is more than two, so the
first jar has more teddy bears than the second. The second jar has less teddy bears
than the first. We can use counters or blocks or
other equipment to help us model the numbers in each group. That helps us to compare the groups
more easily to see which has more and which has less. Let’s practice comparing groups of
objects to find which group has less.
Is the number of apples less than
the number of strawberries?
We’re shown a number of apples and
a number of strawberries. The question asks us if there are
less apples than strawberries. The apples and the strawberries
have been matched together using lines. Le-f strawberries. One, two, three, four. There are one, two, three
apples. We know there are more strawberries
because we can’t match this strawberry to an apple. There aren’t enough apples. Three is less than four. Four is more than three. So the answer to the question, “Is
the number of apples less than the number of strawberries?”, is yes because three is
less than four.
Which group has fewer birds?
The word fewer is another way to
say less. We have to find the group, which
has less birds. We could use string and some beads
to help us compare the amounts of birds in each group. Each time we count a bird, we could
add a bead to the string. Let’s count the birds in the first
group. One, two, three, four, five. The first group has five birds. Let’s count the birds in the second
group. One, two, three. We’re looking for the group with
fewer birds. So we’re looking for the piece of
string with the least number of beads. The string with three beads is the
shortest. So the group which has fewer birds
is the group with three birds. Three is less than five.
Are there fewer dogs than
To help us answer this question, we
need to compare the dogs and the ducks. Let’s make a group of dogs and a
group of ducks. There’s one dog, two dogs,
three. Now, let’s count the ducks. One, two. The group which has fewest animals
is the ducks. Two is less than three. So the answer to the question, “Are
there fewer dogs than ducks?”, is no. There are more dogs than ducks. There are fewer ducks than dogs.
In this video, we’ve learned how to
compare groups of objects to see which has less.
