Olivia is counting beads on a
string. Complete using more than, less
than, or equal to. The number of blue beads is what
the number of red beads.
This question is all about
comparing two groups together. Can you see the two groups of
objects that we’re looking at? It’s the beads that are on this
string. There are a group of blue beads and
a group of red beads. And we need to compare the group of
blue beads with the group of red beads because we’re given a sentence to complete:
the number of blue beads is what the number of red beads. Is it more than the number of red
beads? Is it less than the number of red
beads? Or are the two groups the same? Is the number of blue beads equal
to the number of red beads?
Perhaps if these were objects in
real life, maybe beads or counters, we could compare them by matching them up. But in this question, this is just
a picture of the objects. So how can we compare these
groups? Let’s count them. How many blue beads can we see? One, two, three, four, five, six,
seven, eight, nine, 10, 11, 12. The group of blue beads contains 12
beads. And the group of red beads contains
one, two, three, four, five, six, seven, eight, nine, 10, 11, 12. This is interesting. We counted 12 blue beads but also
12 red beads. These groups are exactly the same
size.
So are we going to use more than,
less than, or equal to to compare our groups? Well, we know that the word “equal”
means the “same as.” Both groups contain 12 beads. And so we can say the number of
blue beads is equal to the number of red beads. Our missing words are “equal
to.”
