Big ideas
Do this: Read each idea. Explain what you would need to know about a number before using it.
DataThe values you work with.Exactly: Represented values such as numbers, typed characters, or sound samples.Mix-up alert: Data are not only numbers. You need context to interpret what values mean.See this in Key words are values represented in a form we can work with. They can be numbers, typed characters, or sound samples. A number by itself may not tell you what it measures.
InformationWhat the data mean in a situation.Exactly: Meaning obtained by interpreting data in context, such as using labeled counts to work out how many chairs a club needs.Mix-up alert: A neat table alone does not explain what unlabeled numbers stand for.See this in Key words is the meaning you get by interpreting data in context. ContextThe details that tell you what data are about.Exactly: Details about what data describe, such as what a number counts. You need context to interpret data correctly.Mix-up alert: A neat table is not context by itself. Labels must say what each value means.See this in Key words tells you what the data are about. The number 18 could mean chairs, minutes, or a room number. You need that detail to use it correctly.
Putting values in a table with clear labels can make their meaning easier to see. Sorting or adding numbers is not enough on its own. You still need to know what the numbers stand for.
HardwareThe physical equipment.Exactly: The physical parts of a computer system, such as a keyboard, microphone, processor, or screen.Mix-up alert: The screen is hardware. The app it displays is software.See this in Key words means the physical parts of a computer system, such as a keyboard or screen. The keyboard can take in your data. The screen can show a result.
SoftwareThe programs and instructions.Exactly: Programs and instructions used by a computer system, such as a spreadsheet or drawing application.Mix-up alert: A button drawn on screen is part of a software interface, not another physical button.See this in Key words means programs and instructions. A spreadsheet app follows instructions to work with your values. Hardware and software work together, but the screen is not the app.
Step-through
Do this: Follow the values. Notice which labels make the numbers useful.
A club needs seats for a meeting. Numbers help only when you know what they mean.

Do this: Read the example. Find the data, the context, and the useful conclusion.
Nia types two counts into a Chromebook spreadsheet: 18 people attending and 15 chairs available. Each person needs one chair. The numbers are data. The labels give context. Subtracting gives 18 - 15 = 3, so the club needs 3 more chairs. That meaning is information Nia can use. The keyboard is hardware; the spreadsheet app is software.
Do this: Explain why putting two numbers in a neat row does not tell their whole story.
Data are not always numbers, and information is not just data in a prettier table. You need context and interpretation. Also, the physical screen is hardware. A button drawn on that screen belongs to the software interface; it is not another physical button.

They are the values you work with.
On the card: Enter or Space flips. Left and Right move. After revealing, 1 marks Still learning and 2 marks Know it. Tab reaches every control.
What are data?
Represented values, such as numbers, typed characters, or sound samples.
What is information?
Meaning obtained by interpreting data in context.
Why is the number 18 not enough to plan seats?
You need context: does 18 count people, chairs, or something else?
Can a typed word be data?
Yes. Its typed characters are data. Data are not limited to numbers.
How do table labels help you use data?
They tell you what the values describe, helping you interpret them.
What is hardware?
The physical equipment of a computer system, such as its keyboard and screen.
What is software?
Programs and instructions used by a computer system, such as a spreadsheet app.
Is a button drawn by an app a separate piece of hardware?
No. The drawn button is part of the software interface. The physical screen is hardware.
How do a keyboard and spreadsheet app work together?
The keyboard is hardware that takes in typed values. The app is software that follows instructions to work with them.

Data are not just numbers.
On the card: Enter or Space flips. Left and Right move. After revealing, 1 marks Still learning and 2 marks Know it. Tab reaches every control.
Can a sound sample be data?
Yes. Data can include sound samples as well as numbers and typed characters.
Does sorting unlabeled numbers tell you what they measure?
No. You still need context to interpret the values.
What turns counts with context into useful information?
Interpreting what the counts mean.
A club has 18 people and 15 chairs, with one chair needed per person. What does it need?
3 more chairs. The labels and the seating need give the counts meaning.
An app shows a button. Which part is hardware?
The physical screen is hardware. The drawn button belongs to the software interface.
Why is a spreadsheet app software rather than a physical part?
Software means programs and instructions, not the equipment.
