There are six bunches of
carrots. There are five carrots in each
bunch. How many carrots are there
altogether?
To help us with this problem, we’re
given a picture that shows us each bunch of carrots and also a calculation, five
plus five plus five plus five plus five plus five equals something. Why are we adding five each
time? We need to add five because there
are five carrots in each of these bunches.
How many times do we need to add
five? We’re told that there are six
bunches of carrots. So, we need to add five six times
to find six groups of five. When we add the same number lots
and lots of times, it looks like quite a long calculation. Another way of writing exactly the
same thing is as a multiplication, six multiplied by five.
What is six multiplied by five? Let’s skip count in fives six times
to find the answer. Five, 10, add another five gives us
15, that’s three fives, 20, 25, and 30. Five, 10, 15, 20, 25, 30, and so we
can say five plus five plus five plus five plus five plus five equals 30. Six multiplied by five equals
30. And so, whichever method we use, we
can say there are 30 carrots altogether.
