Which picture shows the number
11?
In this question, we’re given three
different sets of ten frames. And we’re asked which of these
pictures shows a number. Now, we know when we write a digit
one next to another digit one, we’ve written the number 11. So which of our pictures is a way
to model the number 11? Now, we could think that it’s our
first picture. We can see one counter on the first
ten frame and one counter on the second ten frame. And of course, if we write the
digits one and one next to each other, we write the number 11.
Can we see 11 counters? Of course not. We can only see two. Instead, we need to think a little
bit more carefully about how to make 11. Now, we know the number 11 is the
number that comes after 10. One, two, three, four, five, six,
seven, eight, nine, 10, 11. So we can show the number 11 by
making 10 ones and also one more one. Which of our pictures shows 10 ones
and one more one? Well, it’s this picture here, isn’t
it? We can see a full ten frame. This is the same as 10 counters or
10 ones. And then we can see one more one
sitting on its own in the second ten frame. The picture that shows the number
11 is the one that shows 10 ones and one more one left over.
