One More: Numbers up to 10

In this video, we’re going to learn how to find one more than a number. We’re going to do this by adding one more object to a group and then counting the new number that we have.

Let’s start with a line of fish. How many are there? We could make a line of cubes to help us count. There are one, two, three, four, five. There are five fish swimming along quite happily in the line. But what’s this? We need to make room for one more. We did have five. Now we have one more than five. What is one more than five? To find the answer, we need to count the new number that we’ve made. One, two, three, four, five, six. There are now six fish in the line. We can say one more than five is six. Another way of saying the same thing is six is one more than five.

Now let’s imagine our fish go swimming off, and another group of fish appear. This time, they’re not in a line to help us, but this doesn’t matter. We can still count them. There are one, two, three, four, five, six, seven, eight fish in this group. But what’s this? Think I know what’s coming, don’t you? Looks like we need room for one more. What is one more than eight? We can find out what one more is by counting up to eight and, instead of stopping when we get to eight, counting another number.

Let’s use counters to help us. So remember what we’re going to do. We’re gonna count up to eight, but when we get to eight, we’re not gonna stop. We’re gonna say one more number, one, two, three, four, five, six, seven, eight, nine. One more than eight is nine. It’s the next number we say after eight. And so if you think about it, counting is a little bit like finding one more. Each time we say the next number, we’re finding one more. Let’s practice everything we’ve learned now about how to find one more. We’ll have a go at answering some questions where we have to do just that.

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.

Which picture has one more egg than six?

This question is all about finding one more than a number, and the number we’re given at the end of the question is six. We need to find one more than six. Can you imagine putting six eggs into a frying pan? Maybe not because that sounds like quite a lot of eggs. But imagine you have and then imagine you put one more egg in. Perhaps somebody comes for breakfast that you weren’t expecting. It’s going to make a new number of eggs. And we’re looking for that number. Now, before we start, have a quick look at each of the frying pans with eggs in it. There’s no need to count the eggs yet, but sometimes we can recognize numbers without actually counting.

One of the frying pans has got six eggs in exactly. Can you spot which one it is without actually counting? If you can, we could use this to give us a good idea of which pan it might be that contains one more egg than six. Well, whether you spotted the six eggs or not, let’s start with this first pan. What would you guess? Do you think this has got one more egg than six? Looks like quite a few eggs in this pan, doesn’t it? Well, let’s count them. And as we do to make sure we don’t count any egg more than once, let’s cross them out as we say each number, one, two, three, four, five, six. Well, we can stop counting here, can’t we, because we can see that this pan doesn’t contain one more than six. We can see another three eggs we need to count. This pan contains three more than six.

Let’s try our second pan, one, two, three, four, five, six exactly. This was the pan we mentioned at the start. Perhaps you spotted it already. Because we know that this frying pan has six eggs in it, we can use it to help compare to the others. For example, if we compare our six eggs to the next picture, we can see straightaway that the next picture is going to show less than six eggs, isn’t it? We’d better count just in case, one, two, three, four, five. We were right. We’d need to add some more eggs in this frying pan to get one more than six, wouldn’t we? We’ve only got two more pictures to choose from. The first one contains one, two, three, four, five, six, and we can see one more egg than six. It looks like this picture is the right answer. And if we just check our last picture and we cross off six eggs, we can see that there are two more than six eggs in this last picture.

So we know that the picture that shows one more than six is this one. We’ve answered the question, but we haven’t said what number one more than six is. Let’s find out just to end with. In this pan, there are one, two, three, four, five, six, seven. Seven is one more than six. It’s the next number that comes after six when we’re counting. The picture that has one more egg than six is the one that shows seven eggs.

Count on one more. What is the next number?

In this question, we’re given a picture that shows us a number of counters, and we’re told that we need to count on one more. We need to find one more than this number. We need to find the next number. So perhaps the first thing we’d better do is find out how many counters there are, one, two, three, four. Our picture shows four counters. Now, do you remember what the next number after four is? One, two, three, four, five. The number after four is five. So let’s imagine that we start with four counters, but now we’ve got one more and let’s count on one more. Do you think you know how many there’s going to be? One, two, three, four, five. We started with four and we counted on one more. The next number after four is five.

Complete. What is one more than four?

The “what” in this sentence is going to be a number. What number is one more than four? And to help us with this question, we’re given a picture. It might make you feel hungry because these look like jelly beans. Now we can see a group of these sweets, a group of one, two, three, four jelly beans. But there’s one more jelly bean in the picture, isn’t there? What happens if we include this jelly bean in the group too. What is one more than four?

We know that when we find one more than a number, we say the next number that we’d say if we were counting, one, two, three, four, five. If we start off with four and then find one more than four, we’ll have five. One more than four is five. And so in our sentence, we can say this a slightly different way. Five is one more than four. The missing number in our sentence is five.

So what have we learned in this video? We’ve learned how to find one more than a number. We did this by adding one more object to a group and then counting the new number that we found. We also found out that one more than a number is the same as saying the next number when we’re counting in ones.
