Lesson video

Hi everyone.

My name is Mrs. Jenkins.

We're gonna have such a great time learning together today in this lesson.

Welcome to today's lesson from the unit Using IT to Organise and Present Data.

Today's lesson is called Attributes in Data, and by the end of today's lesson, you'll be able to use attributes to compare objects.

We'll also be touching on our previous learning of tally charts and pictograms. Throughout today's lesson, we're going to be focusing on two key words.

The key words we're going to use are the word attribute.

Can you have a go at saying attribute? Great job.

Now the other word is compare.

Can you say compare? Great job.

Attribute is a thing or quality about an object, like its colour or size.

Compare is looking at two more things to see what is the same or different.

Okay, so those key words that I want you to keep an eye out throughout the lesson is attribute and compare.

In today's lesson, we have split the lesson into two learning cycles.

The first learning cycle we're going to look at is record objects by attribute to create groups.

The second learning cycle is to create and to use pictograms to make comparisons.

So we're going to start with our record objects by attribute to create groups.

Okay, so starting off, I want you to have a really good look at my two groups of objects.

How are these objects grouped? What did you think? The objects are grouped by colour.

There is a red group and a blue group.

Colour is an attribute.

There's that key word.

It is a way to describe the objects.

Objects can be grouped using different attributes.

How do you think these objects have been grouped? So have a little think.

These objects have been grouped by the number of wheels that they have.

The number of wheels is an attribute.

It is a feature that each of these objects have.

So some of the objects have four-wheels and some of the objects have two-wheels.

Objects can be grouped using different attributes.

True or false, objects can only be grouped by their type? How did you do? True or false, objects can only be grouped by their type? It is false.

We can also group objects by their attributes, for example, colour or number of wheels.

How could you sort these objects into two groups? Have a look.

We've got six objects.

How could we sort them into two groups? So how did you group them? We could have grouped them by the number of wheels, so objects with two-wheels and objects with four-wheels.

So the objects could be grouped by the number of wheels.

How could you sort these different objects into two groups? What did you think? I chose to group them whether they could fly or not.

So the objects could be grouped by whether they could fly.

So on the left we have got vehicles that cannot fly, and on the right we have got vehicles that can fly.

You can look at different features that a group of objects have in order to group them by that attribute.

Some of the attributes that you may group by are how many legs does an animal have? What colour eyes do people have? How many wheels does the vehicle have? Which two of the following could be described as attributes? Have a go.

Could be, A, colour, B, distance, or C, number of wheels.

How did you do? Which two of the following could be described as attributes, A, colour, B, distance, or C, number of wheels? The answer is colour or number of wheels.

Both of these are things that could be used to describe an object and also allow us to sort the object.

We've got some monsters now.

How could the monsters be grouped? Have a good look.

Jun says, "I have chosen to group them by the number of eyes each monster has." So we've got monsters with one eye, monsters with two eyes, and monsters with more than two eyes.

The Oak children are having a discussion about recording the data.

Andeep asks, "How could we record the data now the monsters are sorted?" Sam says, "I think we could record them into a tally chart." I think that's a great idea, Sam.

Here is a tally chart to show the number of monsters with each number of eyes.

So in our first column, we've got three different monsters showing each number of eyes.

So we've got one eye, two eyes, and more than two eyes.

So they've counted, we've got our sharing circles to the left so we can count.

There are two monsters with only one eye.

So in our tally chart, we have got two tally lines and that puts our total at two.

For monsters with two eyes, we can check, we can do a tally mark for each monster, and we have three monsters with two eyes.

And then monsters with more than two eyes, we have got two monsters with more than two eyes.

So again, we have two tally marks and the total of two in our total box.

Your challenge today is to record objects by attribute to create groups.

So you are going to create a tally chart of objects in the classroom grouped by shape.

So firstly, you're going to need to choose three shapes.

I have chosen triangle, square, and circle.

You're going to add your chosen shape to the shape column of the tally chart, and going round your classroom, you're going to do a tally chart to record the objects of those shapes that you see.

Have a have a try and see how you get on.

Good luck.

Welcome back.

So you were creating a tally chart of objects in the classroom grouped by shape.

Hopefully you will have chosen three different shapes to hunt for in your classroom.

How did you do? So my tally chart will look different to yours because I've done my tally chart in my classroom, and you may have chosen different shapes, and different children in the class may have chosen different shapes to you.

But hopefully you will have a tally chart with recording the different shapes you have found around your classroom.

I wonder if anyone's got any idea why we might have had an other box.

Good job.

We might have had an other box because there's lots of objects that won't meet our three shapes we have chosen.

We're going to start the second part of our lesson now, so learning cycle two.

We're going to create and use pictograms to make comparisons.

What attribute has Sam used to sort the animals? So we've got three sharing circles with different animals in them.

How has she sorted them? Sam has told us, "I sorted the animals by the number of legs they have." The number of legs is the attribute.

You can record the data collected about objects' attributes on a tally chart.

Once you have a tally chart, you can use it to create a pictogram.

This gives us an opportunity to compare the data and find out the most and least popular objects.

A tally chart can be created to show the number of animals with different number of legs.

So in our first circle, we have got animals that all have four legs.

So in my number of legs column, we've got the number four.

I have got three tally marks to show the three different animals.

And in my total column, I have put the number three.

I wonder if anyone can count how many legs the animals in my second sharing circle have got.

One, two, three, four, five, six.

That's right, each one of those has six legs.

There are four animals with six legs, so I have got four tallies in my tally chart, and I have put the number four.

There's our friend, the spider, and he has got eight legs.

We've only got one of those, so we only need to put one tally and our total number of one in the total column.

The tally chart can be used to create a pictogram.

When creating a pictogram, you only use one animal to make the pictogram.

So we could use a picture of a cow to represent all four legged animals.

All the pictures in the pictogram need to be the same size, so the values can be compared easily.

There's that key word again, compared.

So here is my pictogram, and as you can see, I've got three cows showing animals with four legs.

I couldn't put one of each type of animal because that would've become very confusing.

So I've used one animal to represent four legged animals, and I've put three of them because there were three in my tally chart.

I have used an ant to represent my six legged animals, and again, I could have chosen any of the six legged animals, but I needed to choose one and stick to that one.

And then for my spider, I only actually had the choice of one, but I needed to make sure I have put one spider on my eight legged column.

True or false, data about attributes can be recorded in a pictogram? How did you get on? True or false, data about attributes can be recorded in a pictogram? It is true.

Recording data about attributes in a pictogram allows you to see the most and least popular object.

More monsters have joined the party, so the totals have been increased.

This can be put into a pictogram.

So we can compare our tally chart here.

We have got five monsters with one eye, we have got four monsters with two eyes, and three monsters with more than two eyes.

We can compare that now looking at our pictogram, and straight away, it's really clear to see the most common type of monster is a monster with one eye, and there are fewer monsters with more than two eyes.

Using the pictogram, I see that there were more one-eyed monsters than any other type of monster.

Great observation, Sam.

Thank you.

Which pictogram shows three one-eyed monsters? How did you get on? Which pictogram shows three one-eyed monsters? That's right, it's the middle one.

We can see there are three one-eyed monsters in the middle pictogram.

There are also two two-eyed monsters and four monsters with more than two eyes.

Okay, so here's our second task of the lesson.

You're going to answer the questions based on the pictogram.

So the pictogram shows us vehicles sorted by the number of wheels.

So along the bottom it tells you there's a column of two-wheeled vehicles, a column of four-wheeled vehicles, and a column of six-wheeled vehicles.

How many four-wheeled vehicles? How many more four-wheel vehicles than two-wheeled vehicles? What was the most popular number of wheels? Okay, we've got a second set of questions.

So answer the questions based on the pictogram.

How many six-wheel vehicles? How many more six-wheel vehicles than two-wheel? What was the least popular number of wheels? How did you get on? Let's go through the questions.

So on the first part of the questions we had, how many four-wheeled vehicles? How many more four-wheel vehicles than two-wheel? What was the most popular number of wheels? Okay, so how many four-wheel vehicles? There were six four-wheel vehicles.

How many more four-wheel vehicles than two-wheel vehicles? There were two.

What was the most popular number of wheels? And that was four-wheels.

Let's go through the second set of questions.

How many six-wheel vehicles? How many more six-wheel vehicles than two-wheel? And what was the least popular number of wheels? How many six-wheel vehicles? There were five.

How many more six-wheel vehicles than two-wheel vehicles? There was one.

What was the least popular number of wheels? And that was two-wheels.

You have worked so hard today, and I hope you've enjoyed sorting data by attributes.

Let's summarise what we have learned today.

Objects can be sorted by attribute, which allows you to find different information.

Attributes are a thing or quality about an object, like its size, or a feature such as wheels, wings, or eyes.

The different attributes can be compared by looking at a pictogram to see the most and least popular attributes.

Great job.

I hope to learn with you again soon.
