Lesson video

Hi, everyone, my name is Bishop Safari.

And I'm really excited you decided to join me today for a math lesson.

The unit we're studying is multiplication and division.

In the previous lesson, we focused on finding related multiplication and division facts.

In this lesson, we will focus on calculating the multiplication table of two by skip counting.

So, when you're ready, let's begin.

Let's have a look at today's lesson agenda.

So first, we'll begin by relating skip counting in twos to the multiplication table of two.

Then we'll move on to a talk task.

Next, we'll be solving multiplication problems. And finally, you will complete your independent task.

Before we begin the lesson, you will need the following items. You will need something to write with and something to write on and you will needs a ruler.

So please pause the video now to get the items that you need.

Relating skip counting in twos to the multiplication table of two.

So, before we begin, I would like you to do is to draw a number line from zero to 20.

So please pause the video now.

Great work.

Now, we are going to skip count in twos and what I would like you to do is to follow on your number line, okay.

So my turn, your turn.

One group of two is equal to two.

Great.

Two groups of two is equal to four.

Three groups of two is equal to six.

Four groups of two is equal to eight.

Five groups of two is equal to 10.

Six groups of two is equal to 12.

Seven groups of two is equal to 14.

Eight groups of two is equal to 16.

Nine groups of two is equal to 18.

10 groups of two is equal to 20.

Great work.

So, I would like you to pause the video and answer that following questions, let's read them together.

What do you notice about the numbers in the multiplication table of two? And what's happened to the numbers as you keep skip counting? Pause the video now and share your answers with the screen.

So you might have noticed that the numbers in the multiplication table are even, and that the ones are always an even number, so the ones digit are always an even number.

So, two, four, six, eight, 10, 12, 14 to the four in the 14 16, 18, 20.

The ones digit is always an even number You might also notice that each time you skip count, another group of two is added.

So moving on to a Talk Task, what I would like you to do is to read the equations, then I would like you to skip count in twos on a number line.

And I would like you to find the picture that matches the equation.

Do that now.

Let's have a look at the answers, This is what you should have got.

So first picture, we know that there's one, two, three, four, five, six, groups of two, so six multiply by two is equal to 12 so let's go count two, four, six, eight, 10, 12 okay, the next picture one, two, three, four, five, six, seven, eight, nine, nine groups of two is equal to, let's skip count together two, four, six, eight, 10, 12, 14, 16, 18 okay.

And the next picture, we've got one group of two, the two stalls in one glass, so I know that it's two.

And the next one it says one, two, three, four, five, six, seven, eight groups of two, and let's skip count together two, four, six, eight, 10, 12, 14, 16, and here we have one, two, three, four, groups of two which is two, four, six, eight.

Two groups of two, which equals four, three groups of two, which equals to six.

And finally seven groups of two, which equals 14.

Well done if you've got that correct.

Solving multiplication problems. So before we solve our multiplication problems, let's skip count in twos, okay.

You can use your number line to help you after three one, two, three, two, four, six, eight, 10, 12, 14, 16, 18, 20.

Great work.

So let's have a look at the problem.

Let's read it together.

What multiplication equation does this represent? I would like you to pause the video and write down the multiplication equation on your piece of paper.

Do that now.

Great, so I can see that there are one, two, three, four, groups of two.

So four multiplied by two is equal to eight, two, four, six, eight.

Good work.

What multiplication equation does this represent? Pause the video and write down your equation.

Great work, so here, I can see one, two, three, four, five, groups of two.

So five, multiply by two is equal to 10.

Let's skip count two, four, six, eight, 10.

Great work.

What multiplication equation does this represent? Pause the video now and write down your multiplication equation.

Great work cause I can see one, two, three, four, five, six, groups of two through six multiplied by two is equal to 12.

Let's skip count two, four, six, eight, 10, 12.

Now, moving on to Independent Task, we are selling sweets at the school fair.

Each sweets costs two p, or two pence and your task is to create the price list for the sweets sold at the school fair, okay.

So, you're going to start with one sweet and all the way until 12 sweets and here you're going to write down, we're going to draw the two pence coin.

And then you're going to write the multiplication equation to represent your pictures.

Once you're finished, we'll go through your answers together.

Great work.

So let's have a look at the answers to the first one was already done for it.

So we've got one sweet.

So we've got one sweet, one group of two, because I know that one, the value of this sweet is two p.

So one multiplied by two is equal to two, two groups of two is equal to four, three groups of two is equal to six, four groups of two is equal to eight, five groups of two is equal to 10, and six groups of two is equal to 12.

And if we carry on we knew that seven groups of two is equal to 14, eight multiply by two 16.

Nine multiply by two is equal to 18.

10 multiplied by two is equal to 20 11 multiplied by two is equal to 22.

And 12 multiplied by two is equal to 24p.

Great work if you've got all of that correct.

If you'd like to please ask your parents or carers to share your work on Twitter tagging @OakNational, and #LearnwithOak.

And now it's time for you to complete your end of lesson quiz.

See you next time.
