Introduction to Scratch

The Robot and the Computer

Random student selected - spinner.

Said student leaves the room.

Teacher explains to the rest of the class for the robot to follow and the students, in turn act as the computer and give instructions one by one.

Other teacher to be with robot explaining situation.

Sequencing

Think of different examples of where instructions need to be carried out in the correct sequence.

Dan: - Register, come in in silence think for 2 minutes about examples of sequencing

Learning Objectives & Outcomes

All: Understand the concepts of seqencing, selection and iteration

Most: Will start to explore these concepts in scratch

Some: create a basic scratch program

Sequencing

Selection

Think. Pair. Share

Think of different examples where depending on the choices you make the outcome will be different.

Talon - Think for 1 min

In your groups, give real-life examples of where outcomes are different depending on your choices

Iteration (looping) - What do we mean by iteration in computing?

Iteration (looping) - What do we mean by iteration in computing?

How could we have improve that excercise by using selection and iteration?

scratch.mit.edu

Which of these is of example of iteration?

The series of steps that need to be done order.

Deciding what to do depencing on different situations

Looping instructions

Repeating a sequence of steps depending on given instructions

Hinge - Correct answer is D,

A is Sequencing

B is Selection

C is a non developed answer
