We can skip count by sixes on a
number chart to help us multiply by six. Use skip counting to find six
multiplied by two. And then use skip counting to find
six multiplied by 10.
The first part of this question
tells us that we’re going to be multiplying by six. And to help us do this, we’re told
that we can skip count by sixes on a number chart. Now, we could skip count by sixes
on a number track or a number line, or maybe even just by thinking of the numbers in
our heads. But when we use a number chart like
this, we can not only seal the numbers that we’re skipping, but also we can spot
patterns. If we look at this number chart, we
can see that all of the multiples of six have been written in blue.
Let’s practice skip counting in
sixes to begin with. Six, 12, 18, 24, 30, 36, 42, 48,
54, 60. And each of these numbers is found
by adding six to the last number. But instead of saying every single
number in the grid, we’ve skip counted by sixes. Now that we’ve circled these
multiples of six, can you see what we meant by a pattern? We can see them in diagonal lines
across the grid, can’t we? We can see that they’re all even
numbers, too.
Now, the first thing we’re asked to
do is to use skip counting to find the answer to six multiplied by two. Then, you might look at this
multiplication and say, “Well, this is talking about a number of twos, six lot of
twos, not a number of sixes.” But one thing we know about
multiplications is that we can switch the numbers in a multiplication and it’ll
still give the same answer.
So, we could think of this as six
times two or two lots of six. We could think of six times two as
meaning six repeated twice. So, let’s count in sixes twice to
find the answer. Six, 12. We skip counted by sixes twice to
find the answer. Two lots of six are 12.
Next, we’re asked to use skip
counting to find six multiplied by 10. And again, we can think of this as
10 times six or skip counting by sixes 10 times. Well, we know how far we get when
we skip count by sixes twice, so let’s carry on counting from there. 12 and then 18, 24, 30. That’s five sixes. Let’s carry on skip counting
another five sixes. 36, 42, 48, 54, 60. This time, we’ve skip counted by
sixes 10 times. And the last number we said was
60.
So, we use this number chart to
help us skip count by sixes and find the answer to these six times tables facts. Six times two equals 12 and six
times 10 equals 60.
