It's ok to be wrong

What would happen when we run this code?

The program would say the word HELLO as 100 is greater than 50.

This program uses SELECTION

SELECTION is when you make a choice in a program.

It usually uses the words IF and ELSE

Here is another example where there are two queues for a ride.

IF you have the fast pass then you can go in the left queue.

ELSE you have to go in the other queue

Learning objectives

Understand what selection in programming means.

Create a program in Scratch using selection.

"Selection is a decision or question. 

At some point, a program may need to ask a question because it has reached a step where one or more options are available. 

Depending on the answer given, the program will follow a certain step and ignore the others."

Modify

I want a program that asks a single quiz question “What is the capital city of Spain?”

If the user gets the answer correct (Madrid), then it should add 1 to the score and say “That is correct”.

If the user doesn’t answer correctly, the program should say “Incorrect”.

Your challenge is to rearrange the blocks to form a working program.

MODIFY

Creating a quiz

Here we can put SELECTION blocks inside each other to make a simple multiple choice question.

This is triggered when a sprite is clicked.

MODIFY

A points system

You can even create a variable and add 1 to it every time you get a question correct

Make

Write a program in Scratch that acts as a quiz. The quiz should have multiple questions.

 

 

 

Consider adding variables to your quiz so that the player gets points for each question they get correct.
