Lesson video

Hello mathematicians, it's me, Miss Charlton, and my ever so helpful talk partner, Hedwig, I'm wondering if she'll stay awake all lesson this time, ready for some more learning.

Now this lesson is the last one in the unit about shape and the language using the language of direction and position and movement.

So this lesson, we're going to consolidate our learning that means recap it and check what we have learned.

So we're going to Follow directional instructions to create 2D shapes.

Then we're going to use the language of shape properties and of position, direction and movement so that you can do an exciting Independent Task, and then complete your End of Lesson Quiz.

For today's lesson, you're going to need some paper and a pencil.

Let's go through our star words.

Now these are some of the words that we've used before in previous lessons, but we're going to recap them.

So get hands ready, hands ups star words, forward, right, left, quarter turn.

Remember that quarter turn that we were learning about, you'll need that in today's lesson.

So I just want to say a huge well done with our friend, the alien who only speaks in algorithms. You have done such an incredible job and worked so hard in this unit, learning all about the language of position and direction of movement, as well as learning about the properties of different shapes and how to recognise them.

And so today's lesson, we're going to put all of that learning together to complete a task.

But don't worry if you've missed lessons along the way, because you're still going to have a great time in today's lesson.

Your job is to follow this algorithm, this set of instructions to see if you can complete the algorithm and see what it reveals because it's going to reveal something as a shape at the end.

Once you've revealed that shape, you need to use your knowledge of the properties of shape to describe what you can see.

So for example, my algorithm says, forward two, quarter turn right, forward two, quarter turn right, forward two, quarter turn right, forward two now describe the properties of that shape you have created.

So my first instruction on my algorithm is forward two so for example, I would go forward, one, two, then it says quarter turn, right.

So you need to figure out how you can turn a quarter to the right like that forward two.

You might find it easier to walk this route yourself.

So get up and pretend that you're doing it.

You might like to use counters to help you on the dots Now don't worry if you haven't got.

If you can't get the worksheet, you can draw the dots just like I have done here.

Once you've done that, you've got another algorithm to do.

So this one you have to go forward three for a start.

And once you've completed the shape, you need to describe the properties of that shape to figure out what the shape is called.

Pause the video now, have a go with that and then come back and we'll check what shapes you managed to find at the end.

How did everybody get on? So on my one I found a square.

I followed the algorithm carefully and created a square and then I described it.

It has four lines, the lines are of equal length, the lines are straight.

There are four vertices and it is a special kind of rectangle.

Those are the properties of a square.

And the second one it revealed a rectangle.

And then I described the properties of the rectangle, there are four lines, two lines longer than the other two, the lines are straight, and they have four vertices.

So you use the language of position, direction and movement to follow an algorithm to figure out a shape, which you then described.

That's a huge amount of learning everybody, really, really well done.

If you didn't find those shapes.

Don't worry, it was a very tricky activity.

But you might like to try it again to see if you can figure it out this time.

You might even like to write your own algorithm to create your own shapes.

I'd love to see some of the algorithms that you've been writing and some of the shapes that you've been creating.

So if you'd like to, you can ask your parent or carer to share your work on Twitter, and make sure you do the hashtag, the #LearnwithOak and you'll find it @OakNational.

Now just before you disappeared to go and write your own algorithms, let's see if Hedwig understands what we did.

Wakey, wakey, Hedwig, right.

So first of all, we have to follow directions, instructions and algorithm to create a 2D shape.

And then once we revealed those 2D shapes, we were able to use the language of shape properties, for example, vertices, and straight lines to be able to describe which shapes we had found.

It was a very tricky activity, Hedwig, but I had a lovely time exploring.

When I did that activity by myself.

I made loads of mistakes in it to begin with, especially when I had to do quarter turns either way, but I kept on going and kept on trying, and then I got there in the end.

Hedwig, do you think you'd be able to write an algorithm for your route to your barn where you live? You must have taught her really well because she seems confident that she can write her own algorithm now.

Well done everybody had a lovely time learning with you today.

See you very soon.

Bye.
