🎮 Level 

A level is a stage or part of a game. As the player moves to higher levels, the game usually gets more difficult.
🗣 “I reached Level 3, and now the background changed and the enemies move faster!” 

🎯 Condition 

A condition is a rule the game checks to decide what to do next. It often uses if… then.
🗣 “If my score is greater than 10, then the game switches to the next level.” 

📣 Broadcast 

To broadcast means to send a message in the game that tells sprites or scripts to start doing something.
🗣 “I used broadcast ‘game over’ to show the end screen when the player lost all their lives.”

🧮 Variable 

A variable is like a container that stores information in your game, such as the score, number of lives, or the level.
🗣 “I used a variable to keep track of how many coins the player collected.” 

📣 Broadcast 

To broadcast means to send a message from one sprite to another, or to the whole game, to make something happen.
🗣 “When the player wins, I broadcast a message to show the victory screen.” 

❓ Condition 

A condition is a rule that tells the game what to do if something happens. It often uses if… then… or if… then… else….
🗣 “If the player touches a spike, then they lose a life.”

Sequencing is the specific order in which instructions are performed in an algorithm.

An important skill that programmers need is to be able to communicate with others, especially when they are working out what the program should do. They also need to be persistent when finding and fixing bugs. Bugs happen all the time in programming, so being able to identify where the bug occurs and problem solving how to fix it is incredibly important.

A Quick Look at Early Computers

The first computers weren’t very fancy. One of the earliest examples was the abacus, invented in Babylon around 500 B.C. It was made of string and beads, and its main purpose was to count and keep track of money or goods.
Later, in the 1600s, two inventors created early calculators that used gears and wheels to perform simple mathematical tasks — an important step toward the computers we use today.

Processing: The computer’s thinking.
Storage: The computer’s memory.
Communication: Sending and receiving data between computers.

Let’s build a tiny game where:

• One sprite moves using the arrow keys
• Another sprite spins or plays music when clicked
• You create your own goal (like catching something or changing colour)

🧠 Summary

• You used blocks to move and animate sprites
• You created your own animation or game
• You practised sequencing, events, and debugging

Did you know

In Scratch, a “backdrop” refers to the background image displayed on the stage, essentially the scene or setting where your sprites (characters) interact; it’s like the scenery behind the actors in a play, and you can change it to set the mood or context of your project.

Did you know

The first version of Scratch was released in 2003? That means it’s over 20 years old!

Remember

The opposite (inverse) of division is multiplication.
Example: 6 × 5 = 30 so we know that 30 ÷ 5 = 6.

When we estimate, we make a good guess based on what we know.

To estimate an answer, we round numbers off to make them easier to work with. For example, 598 ÷ 3 is not easy to calculate. If we round up 598 to 600, the calculation is much easier.

We know that 6 ÷ 3 = 2. So 600 ÷ 3 = 200.

We know that the answer to 598 ÷ 3 will be close to 20

frequency: the number of times an event occurs

tally: a mark used to keep count of the number of times something happens
