Making Five

In this video, we will learn how to use models and addition equations to show different ways to make the number five. We can make the number five in different ways. How many different cube trains could we make using orange and pink cubes? We could make a cube train using five orange cubes. One, two, three, four, five.

We could write down how many orange cubes and how many pink cubes we used to make our cube trains. This will help us make sure that we don’t make the same cube train twice. We made our cube train using five orange cubes and no pink cubes. We could also make a five train using four orange cubes and one pink.

Have you spotted the pattern? Can you predict which cube train will be next? Five, four, five, four, three. The number of orange cubes is decreasing. We’re taking away one each time. How many pink cubes will there be? Zero, one, two. The numbers are increasing. We’re adding one pink cube each time. Five and zero, four and one, three and two. Can you use the pattern to predict what the next pair of numbers will be?

Five, four, three, two. How many pink cubes should there be? Zero, one, two, three. Two orange cubes and three pink cubes makes five. The next pair would be one orange cube and four pink. One and four makes five. And our final pair of numbers that make five are zero and five. Five and zero, four and one, three and two, two and three, one and four, and zero and five are all pairs which make five. Did you spot the pattern?

Five, four, three, two, one, zero, zero, one, two, three, four, five. We found six different ways to make a five train. Let’s practice some questions now using models to find different ways to make five.

Choose the sum that equals five. Is it one plus two, one plus three, two plus three, one plus one, or two plus two?

Does one and two equal five? Let’s make a cube train to find out. One add two makes three. One, two, three. We know that one and two doesn’t make five because we still have two of our five cubes left over and two spaces in our five frame. Does one and three make five? We added one and then two.

To find the total of one and three, we just need to add one more cube to our train. One and three doesn’t make five either. We still have one of our five cubes left over. Does two and three make five? We know that one and three makes four. And we know that two is one more than one. Two and three does make five. The sum that equals five is two plus three.

Find the missing number. Four plus one is five. Three plus two is what?

We know that four orange stars and one green star is five. The second picture shows three orange stars and two green stars. But we’re not told the total number of stars. Let’s put all of the stars together in a five frame. One, two, three orange stars and two green stars. How many stars are there in total?

Well, we don’t need to count them because the five frame is full. Three plus two is five. The missing number is five. Four and one is five, and three and two is five.

Use the blocks to help you answer the questions below. Fill in the blank. Two and three make what? Which number bond is correct? Whole five, part two, and part three. Or whole two, part five, and part three. Or whole two, part five, and part three.

The question tells us to use blocks to help us answer the questions. And the first question asks us to find the total of two and three. The model shows two red blocks and three blue blocks. How many blocks are there in total? Let’s count them. One, two, three, four, five. Two and three is five.

The second part of the question asks us to find the number bond which is correct. Which of these three number bonds shows us that two and three make five? Well, we already know that the whole part or the total should be five. The whole part of the first number bond is five. The whole part of the other two number bonds is two, which is not correct. The total of two and three is five.

Let’s check if the rest of the number bond is correct. We know that part of our model shows two red cubes. And the second part of the model shows three blue cubes. Two and three make five. The correct number bond shows us that two and three equals five.

What have we learned in this video? We’ve learned that we can use models to help us find different ways to make five. We’ve also learned that we can record our system to help us find all the possible answers. And we also learned that we can record different ways to make five using a part–whole model.
