There are seven squares. Pick the model that has one more square.

How good are you at finding one more than a number? In the first picture, we can see some colored squares in a line, and we’re told there are seven of them. And then we’re given some more models just like this. But we’re told to pick the one that has one more square, in other words, one more than seven. Now what does one more than seven look like? Well, if we put one more square onto our row at the top, it would look like this. Instead of seven squares, we’ve now made a new number, and this number is one more than seven. It’s the next number after seven. Can you guess what number we’re looking for? One, two, three, four, five, six, seven, eight. One more than seven is eight. It’s the next number we say after seven. And so we’re looking for a row of squares that has eight squares in it.

Do you think our first model has eight squares? Looks like this line of squares is a little bit short, doesn’t it? Let’s count the squares anyway. One, two, three, four, five, six. This model didn’t even get as far as seven squares, let alone one more than seven. This isn’t the right answer. Our second model looks like it might be longer than seven squares. Do you think this one might be eight squares long? Well, you know, we can be a bit clever with this one, and we can look at it very carefully before we begin to count. Look at the colors of each square in each model. They all begin with a yellow square and then it goes yellow, green, yellow, green, and so on, doesn’t it?

So when we look at our seven squares at the top, what color are we expecting the eighth square to be? The seventh square is yellow. So we’d probably expect the eighth square, the last square, to be green, wouldn’t we? But in the second model, we can see that the last square is yellow. Let’s make a guess. Do you think this is going to be the right answer or not? We’d better count to find out. One, two, three, four, five, six. Well, we’ve got to seven squares, but we can see that this model doesn’t show one more than seven. It shows two more than seven, seven, eight, nine squares. Looks like we were right with our guess about the colors, weren’t we? So we’re only left with one more model.

This time, it does end with a green square, so it looks like we might be right, but there’s only one way we can find out. One, two, three, four, five, six, seven, and one more than seven is eight. Eight is one more than seven, and so we were looking for the model that had eight squares in it. We started off with seven squares, and the model that has one more square than seven squares is the one that contains eight squares.
