Lesson video

Hello everyone, my name is Miss Sabzvari and I'm really excited that you decided to join me today for our maths lesson.

The unit that we're studying is multiplication and division.

In the previous lesson we focused on calculating the multiplication of table five, by skip counting.

In today's lesson, we will focus on calculating the multiplication table of 10, by skip counting.

So, when you're ready, lets begin.

Lets have a look at today lesson agenda.

First we'll begin by relating skip counting in 10's to the multiplication table of 10.

Then we'll move on to our talk task.

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

Before we begin today's lesson, you will need the following items. You will need something to write with and something to write on.

And you will need a ruler.

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

Relating skip counting in 10's to the multiplication table of 10.

Before we begin, what I would like you to do is to pa use the video here and to draw a number line from zero to a 100.

Okay? Do that now.

Great work.

So, now we are going to skip count in 10's.

And what I would like you to do, is to follow on your number line.

Okay? My turn, your turn.

One group of 10 is equal to 10.

Two groups of 10 is equal to 20.

Three groups of 10 is equal to 30.

Four groups of 10 is equal to 40.

Five groups of 10 is equal to 50.

Six group of 10 is equal to 60.

Seven groups of 10 is equal to 70.

Eight groups of 10 is equal to 80.

Nine groups of 10 equal 90.

And 10 groups of 10 is equal to 100.

Great work! So, now what I would like you to do is to answer the following questions.

Okay? Follow with me.

What do you notice about the numbers in the multiplication table of 10? What happens to the numbers as you keep skip counting? Pause the video now and tell your screen the answer.

Good work.

So you might have noticed that the numbers in the multiplication table of 10 end in zero and they are even numbers.

You might have also noticed that each time you skip count, another group of 10 is added.

Okay? Moving on to our talk task.

What I would like you to do is to first read the equations, then I would like you to skip count in 10's on a number line.

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

And once you're finished, we'll go through the answers together.

Great work! So, having a look at the first picture, I can see that there are one, two groups of 10.

So I know that two groups of 10 equal 20.

The next picture I can see that there are one, two, three, four, five, six groups of 10.

And six groups of 10 equal to 60.

Lets check.

10, 20, 30, 40, 50, 60.

Great work.

The next picture I can see that there are one, two, three, four, five groups of 10.

And five groups of 10 is equal to 50.

Next I got one group of 10 which is equal to 10.

Than I have one, two, three, four, five, six, seven groups of 10.

Which equals 70.

And finally, I can see that there are four groups of 10, which is equal to 40.

Well done if you got that correct.

Solving multiplication problems. Lets skip count in 10's before we move on to our problems. Are you ready? After three.

One, two, three.

10, 20, 30, 40, 50, 60, 70, 80, 90, 100.

Great work.

So, follow with me.

What multiplication equation does this represent? What I would like you to do, is to pause the video and write down the multiplication equation.

And once you're finished, we will go through the answers together.

Great.

So, I can see that there are one, two, three, four groups of 10.

And I know that four groups of 10 is equal to 40.

What multiplication equation does does this represent? Again, pause the video now and write down you're multiplication equation.

Good job.

I can see that there are one, two, three, four, five groups of ten.

And I know that five groups of 10 is equal to 50.

Lest skip count.

10, 20, 30, 40, 50.

Great work.

Looking at our next picture, what multiplication equation does this represent? Pause the video now and write down your equation.

Good work.

So, I know that there are one, two, three, four, five, six groups of 10.

And I know that six groups of 10 is equals 60.

Lets skip count together.

10, 20, 30, 40, 50, 60.

Good work.

Moving on to our independent task.

Follow with me, the school cook is making cakes for the end of term.

The recipe says she needs 10 eggs to bake one cake.

Luckily the eggs come in boxes of 10.

How many eggs does she need to bake the cakes in the table? So, again the first one is being completed for us.

We're going to start with baking one cake and then we're going to move to two, three, four, five all the way down to 12.

Okay? And each cake requires 10 eggs.

Okay? So what you need to do is write down the number of cakes, then to draw the picture of the number of.

Or the boxes of eggs that are needed.

And to write down the multiplication equation.

And once your ready, we will go through the answers together.

So, lets have a look at the answers together.

I know that two lots of 10 is equal to 20.

Three lots of 10 is equal to 30.

Four lots of 10 is equal to 40.

Five lots of 10 is equal to 50.

And six lots of 10 is equal to 60 eggs.

Seven lots of 10 is equal to 70.

Eight lots of 10 is equal to 80.

Nine lots of 10 is equal to 90.

10 lots of 10 is equal to 100.

11 lots of 10 is equal to 110.

And 12 lots of 10 is equal to 120.

Well done if you got all of that correct.

And if you'd like to, please ask your parent or carer to share your work on twitter, tagging @OakNational and #LearwithOak.

And now its time for you to complete your end of lesson quiz.

See you next time.
