Are there 17 balloons?

In the picture, we can see some red
balloons, and our question asks about them. Did you notice there was a number
in our question? We write this number as a one
followed by a seven. And do you remember how to say this
number? You may have heard it said in the
question, if you’re listening carefully. It’s the number 17. And our question asks us, is this
how many balloons there are? Are there 17 balloons? The answer to this question is
either going to be yes or no. And there’s only one way to find
out. We need to count them. Now what do you notice about the
way these balloons have been shown? They’re inside two ten frames,
aren’t they?

And if we look carefully at the
first ten frame, we can see that it’s completely full. There are no gaps in our first ten
frame. This means it looks like there are
10 balloons in there. Should we count them? One, two, three, four, five, six,
seven, eight, nine, 10. We were right. A full ten frame means 10
balloons. Now how many more than 10 can we
see? In the second ten frame, there are
another one, two, three, four, five, six balloons. This is interesting because we’re
looking for 17 altogether, aren’t we? And one thing we know about the
number 17 is that it’s seven more than 10. But we’ve just counted six more
balloons than 10. It looks like we might not have 17
balloons. So far, we’ve got as far as 10.

So let’s say 10 and then carry on
counting for our six more balloons and see how far we get. So we’ll start with 10 and then 11,
12, 13, 14, 15, 16. Six more than 10 is 16 not 17. So when we’re asked, are there 17
balloons, we can say, no.
