Lesson video

Hello everyone, my name is Mrs. Jenkins.

I can't wait to learn with you today.

Welcome to today's lesson.

This lesson is from the unit, Using IT to Organise and Present Data.

Today's lesson is called Entering Data, and by the end of today's lesson, you will be able to enter data onto a computer and answer questions using a pictogram.

We have two key words we are going to look at today in the lesson.

The first word is the word data.

Can you say data? Great job.

The second word is the word pictogram.

Can you say pictogram? Great job.

Data is numbers, words, or pictures collected to learn something.

And a pictogram is a chart that uses pictures to display data.

So those two key words, data and pictogram, we'll be looking at those throughout today's lesson.

We have two key learning points we're going to look at today.

We are going to be able to enter data onto a computer and answer questions using a pictogram.

Our first one we're going to look at is enter data onto a computer.

Let's get started.

Data can be letters, numbers, or words that have been collected.

Data can be collected by asking people questions, looking at objects or measuring something.

A pictogram is a chart that uses pictures to display data.

We can make them using pens or/and paper, or we can use a computer.

This pictogram shows what a group of children had for breakfast.

Along the top we have our title, Our Group's Breakfast, along the bottom, we have the labels for each of the choices of toast, pancakes, and cereal and then we have our pictures.

Each picture of a different breakfast above the line represents one child's answer.

Seven children were asked what they had for breakfast and recorded it using a pictogram.

For each person's answer, a picture of their breakfast food was added.

So let's have a little check at how we've got on so far.

How many children said that they had cereal for breakfast? How did you get on? So the question was, how many children said that they had cereal for breakfast? That's right, three children said that they had cereal for breakfast.

There are three bowls of cereal in the pictures on the pictogram.

Only one person had pancakes for breakfast and three children had toast for breakfast.

You can create pictograms on a computer using our web link.

It enables you to create different pictograms based on the data you are collecting.

Pictograms can be created using the data that has been collected in a tally chart.

So you can collect your data in a tally chart and then use that data to create your pictogram.

This is a picture from the website and we can see we have our five different types of fruit.

The pictures underneath the add and minus signs show the type of data that is being collected.

You do not count this picture, it's a bit like a label.

Jun has said, "I asked my family what their favourite fruit was from my list.

Apples, bananas, oranges, pears, or strawberries.

They could only choose one fruit from my list." So we can see Jun has made a tally chart to show the different fruits.

Four people chose apples, three people chose bananas, one person chose oranges, two people chose pears, and six people chose strawberries.

This data can then be used to create a pictogram.

Jun has said, "Each time a member of my family chose their favourite fruit, I clicked on the add next to their chosen fruit.

This will show the data I have collected." Using the data from the tally chart, Jun has made a pictogram showing his family's favourite fruits.

And here we can see all the fruits laid out exactly the same amounts as was on our tally chart.

Oh, we've got a little check now what data will be collected for this pictogram? How did you get on? Our question was, what data will be collected for this pictogram? The answer is the data is about fruit.

And we can tell that because our title is Our Favourite Fruit and there are five pictures of fruit along the bottom.

Okay, so here is going to be your task.

You are going to create a pictogram showing how people travel to school.

So to begin with, we need to go to the web link and there are some templates on the web link.

So if you scroll down on the templates, you'll be able to choose Journey, and if you click on Journey, you will then be able to use the add button to add your data.

You are going to use the data on the next slide to make your pictogram.

Okay, so here is our tally chart that is going to give you the data you need to make a pictogram.

Okay, so you can see we have got four people using a bicycle, six people using a bus, two people using a car, and one person walking.

Have a go.

How did you get on? We were making a pictogram using the data given.

So let's compare.

Does your pictogram look like mine? Above the line, I have got four bikes, I have got six buses, two cars, and one walking.

Great job.

We are going to move on now into our second learning cycle, answer questions using a pictogram.

It is important to have a reason to collect data.

Jun has told us, "I'm having a party soon and I want to find out how many of each fruit to get." So he has done his tally chart to see what fruit everybody liked.

Making a pictogram makes it really easy to see which items were most popular.

You can use this information to answer some questions.

Answering questions, the pictures underneath the add and minus sign show the data that is being collected.

When you count the number of objects, you do not count this one, I like to think of it as a label to tell me what type of data I am collecting.

Okay, we're gonna do a little check now.

True or false, we should count the bottom item below the line in our pictogram? How did you get on? My question was, we should count the bottom item below the line in our pictogram, true or false? The answer is false.

The picture below the line is a label to show us what we are counting, it should not be counted in our pictogram.

To find out how many people were asked in a pictogram, we can count the amount of objects above the plus/minus line.

This will give the amount of people questioned so we can add up the amount of apples, bananas, oranges, pears, and strawberries to find out how many people were questioned.

Okay, quick check here.

How many people did we ask in total? Was it A, 17, B, 21, or, C, 10? Have a go.

Welcome back, how did you get on? I asked you, how many people did we ask in total for this pictogram? Was it, A, 17? B, 21, C, 10? Well done, the answer is 17 and we can check that by adding three apples, add four bananas gives us seven, add two oranges gives us nine, add three pears gives us 12, and add five strawberries gives us 17.

Well done if you got that right.

We are going to go onto second task now.

You are going to have a go at answering questions using a pictogram.

Now to make things a little bit trickier, we've got two different pictograms, so this is the first one and the first set of questions.

How many people chose bananas? How many people chose oranges? Which fruit got the most votes? Off you go.

How did you get on? I asked you, how many people chose bananas? How many people chose oranges? And which fruit got the most votes? So we've got four people chose bananas, and we can check that, we can count them, one, two, three, four.

How many people chose oranges? Two people chose oranges, and we can check that one, two.

Which fruit got the most votes? Strawberries got the most votes, and we can see that their pictogram is much taller than the others.

We can now move on to the second part of our task and we're gonna answer some questions about transport.

How many people travelled by car? How many people were asked? And what was the most popular way to travel? Have a go.

How did you get on? I asked you, how many people travelled by car? How many people were asked? And what was the most popular way to travel? So how many people travelled by car? Two people travelled by car.

How many people were asked? That was 13.

So we can check that because we have got four bicycles added to six buses, which gives us 10, add two cars, which is 12, add one walking, which is 13.

And what was the most popular way to travel? And that was by bus.

Well done if you got those right.

Well done, you've worked so hard today.

Let's summarise what we have learned.

Data is number, words or pictures to learn something.

Data can be entered onto a computer.

A computer can be used to create a pictogram.

It is a different way to present data.

Pictograms can help you answer questions about objects.

Great work, I hope to see you all again soon.
