Lesson video

Hello, everyone.

My name is Mrs. Jenkins.

I can't wait to learn with you today.

Welcome to today's lesson from the unit using IT to organise and present data.

Today's lesson is called presenting information clearly, and by the end of today's lesson, you will be able to present information on a computer.

We have three keywords we're going to look at in today's lesson.

Let's have a look at them.

We have the word present.

Can you say present? Good job.

The word information.

Can you say information? Great.

And the last word is the word anonymous.

Can you say anonymous? Good job.

When we use the word present, we mean showing or sharing information in a way that others can understand.

When we use the word information, we mean important knowledge or facts from the data we have collected.

And when we use the word anonymous, it's when something is done or shared without revealing who it is about or who did it.

So remember, we are looking for these three words throughout today's lesson, present, information, and anonymous.

We have two learning cycles today.

We have present information using a computer and decide when information should be shared.

We're going to start the first learning cycle, present information using a computer.

Data can be collected in a tally chart.

It is quick and easy as it just needs a pen and paper.

The objects are counted and recorded by one tally mark for each object.

The marks are added up to create the total.

So we've got an example here, the tally to show the number of monsters with each number of eyes.

The first monster only has one eye, and there are five.

The second monster has two eyes, there are four, and monsters with more than two eyes, there are three of.

Once the data has been collected, it can be presented in a pictogram.

The pictogram can be used to gather information.

So here, we've got our tally chart showing us our totals, but then we can see in our pictogram our monsters representing each one of these options.

So monsters with one eye, two eyes, and more than two eyes.

Are there any other ways we could present data? Yes, we could present the data in a block chart.

And as you can see here, we have got a block chart showing the same data in a different way.

True or false? A block chart is a way to present data.

How did you get on? I asked you, true or false? A block chart is a way to present data.

Good job.

It's true.

Block charts are a way to present data.

Pictograms are also a way to present data.

Information can be presented in a block chart.

This can be created on a computer from the data that you enter.

So, on the left, you can see there is a little table where I have filled in the information.

I have put one eye, two eyes, and more than two eyes for my item.

I have put the number of each item next to it.

So, for one eye, there was five, two eyes, there was four, for more than two eyes, there was three.

This is then shown in my block chart.

Here are some similarities between a pictogram and a block chart.

They both show data visually, they can both be used to compare data, and they are both easy to read and understand.

The differences: pictograms use pictures, and block charts use blocks, pictograms can be slightly harder to read than block charts, and block charts can be quicker to create because you don't need to add every single picture in.

Using a block chart makes it easy to see the exact amounts of each object.

It also makes it easy to be able to compare the different amounts.

Each column is a different colour, which helps to see the differences.

So here, we can see, along this left side, the scale is going up in ones at the side.

Each block represents one count.

Each section has a different colour, and each item is labelled underneath.

Okay, let's have a little check now.

How many apples does the chart show? A, two, B, four, or C, three? Have a go.

How did you get on? I asked you how many apples does the chart show.

A, two, B, four, or C, three? The answer was A, there are two apples, and we can see there are two blocks on the chart above the word apple.

Today, you are going to create a block chart showing the most popular way of travelling to school.

You are going to go to the web link, and you are going to choose a blank template.

Using the data from the tally chart, we can fill in the table on the computer.

So we can put in car, walk, bike, and bus for items, and then we can put the numbers five, eight, four, and two for the total amount of children that said they had travelled that way.

Okay, so your task is to create a block chart on a computer using the data from the tally chart.

So I've given you some new data about the class's favourite sport.

You will need to, first of all, fill in the table with the categories.

So the categories are football, swimming, rugby, and tennis.

You will then, under number, put the total next to each item.

Have a go.

Let's see how you get on.

How did you get on? I asked you to create a block chart on a computer using the data from the tally chart.

Does yours look like mine? I showed there were eight people choosing football, seven choosing swimming, five choosing rugby, and three choosing tennis.

Hopefully, yours looked a little bit like mine.

We're going to move on to our second part of the lesson today, decide when information should be shared.

Is it always okay to share information? Some things are important to keep private.

When collecting data about people, it is important to remember that some of this is called personal information.

Personal information should not be shared unless it is a safe place to do so.

Personal data is information about you that could help someone figure out who you are.

This can be your name, where you live, or even your favourite food.

Some people might use personal data to trick you or cause harm.

That's why it's important to keep your information safe and only share it with people you trust.

Andeep says, "I don't think we should tell everyone our names or where we live.

It might not be safe." Lucas has replied, "You're right, Andeep.

We should only share personal information with people we trust, such as our parents or teachers." You're so right, Lucas.

Thank you.

Let's have a check.

True or false? All information is safe to be shared with anyone.

How did you get on? I asked you, true or false? All information is safe to be shared with anyone.

That's right, it's false.

Some information is called personal information and should only be shared with people we trust.

In this unit, data has been collected using tally charts.

When collecting the data using a tally chart, tally marks are used, and names are not recorded.

This keeps the data anonymous.

Anonymous means that no one knows who it belongs to.

This is a good way of collecting data without collecting personal information.

So that was our keyword there, anonymous, when something is done or shared without revealing who it is about or who did it.

What information should be kept private? Things like your full name, address, phone number, and pictures of you are private.

You should keep these things safe and share them only with people you trust.

Andeep said, "I can see what we should not share, but what is safe to share?" Lucas has explained, "It's okay to share things like your favourite book, what you are learning, or things about your day, but don't share personal data like your full name or where you live unless it's safe." Thank you, Lucas.

Let's have a little check now.

Which of the following are safe to share? A, your address, B, your favourite book, or C, your date of birth? How did you get on? I asked you which of the following are safe to share? A, your address, B, your favourite book, or C, your date of birth? Well done.

It is your favourite book.

You may share with others what your favourite book is.

Okay, onto our next tasks.

I would like you to have a go at looking at this list and decide which things are safe to share or not.

So we have got full name, favourite colour, hobbies, passwords, the weather, where you will be at certain times, home address, and what you learned at school today.

Have a go.

How did you get on? So I asked you, are the following things safe to share or not? So full name, favourite colour, hobbies, passwords, the weather, where you will be at certain times, home address, what you learned at school today.

Let's have a look at the answers.

So, it is not safe to share your full name as that is giving too much information to some people, but to share your favourite colour? That is okay, and that is safe.

To share your hobbies is also safe.

To share your passwords? Not safe.

We don't want to be sharing our passwords with anyone.

To share the weather, what the weather is doing today? Absolutely, that is safe to share.

Where you will be at certain times, that is not something we want to share with anyone we're not sure about.

Your home address? Also something that is not safe to share with anyone we are not sure about.

And what you have learned at school today, I think that is something that is safe to share.

You've done such a great job today.

Well done.

Let's summarise what we have learned.

Data collected in a tally chart can be presented in pictograms or block charts.

And when we say to present, we mean showing or sharing information in a way that others can understand.

This means that information can be clearly gathered from the data collected.

It is possible to find out the most and least popular answers.

Not all information is safe to be shared.

Information such as names, addresses, and passwords are private information and should not be shared.

Great job, everyone.

You've done really well today.

I hope to see you all again soon.
