Liam has 35 flowers arranged in
seven rows. How many flowers are in each
row?
With a word problem like this, we
need to think carefully about what we need to do to find the answer. And in this particular word
problem, we’re given something to help us. Can you see what it is? Although we don’t need it to find
the answer, we’re given a bar model, and this really helps us to understand what we
need to do to find the answer. Now our bar model doesn’t show Liam
or any flowers. It’s not a picture, but it is a
type of diagram that can help us. Let’s go through the problem and
see how.
Firstly, we’re told that Liam has
35 flowers. Now, as we said already, there
aren’t any pictures of those 35 flowers, but can you see them on the bar model? The number 35 is here, and the way
that it’s labeled it shows us that the whole bar is worth 35. Now, we’re told that Liam’s flowers
are arranged in seven rows. Can you see the number seven
represented on this bar model? Well, it’s not labeled, but we can
see that the whole bar of 35 has been split into one, two, three, four, five, six,
seven equal parts. These are just the same as the
seven equal rows that Liam’s flowers have been arranged in.
So by looking at our bar model, we
can see what we need to do to find the answer. We need to split up 35 or divide it
into seven equal groups. And our answer is going to be the
number in each group. And in this particular problem,
it’s going to show us the number of flowers in each row. So what is 35 divided by seven? Let’s use our knowledge of times
tables to help here. Seven lots of what equals 35? Seven times one equals seven, seven
twos are 14, seven times three is 21, seven times four is 28, and seven times five
equals 35. And because we know seven lots of
five equal 35, we can say 35 divided by seven equals five.
We’ve used a bar model to help us
understand what we needed to do to solve the problem. If Liam has 35 flowers and they’re
arranged in seven equal rows, we know the number of flowers in each row is going to
be the answer to 35 divided by seven. And 35 divided by seven equals
five. There are five flowers in each
row.
