A beginner’s guide to Scratch

Let’s have some fun with the cat
First, let’s give the cat something to say. We’ll start with “Hello, World”. This is
generally the first thing a computer programmer learns to do (don’t ask me why).
As you are now learning a programming language, you’d better start with
“Hello, World”, too.
Making the cat talk
To make the cat say “Hello, World, we’re going to be working with “blocks”.
These are handy pieces of code, each containing an instruction for your sprite
to follow.
There are eight different types of block. These can be found in the top-left corner
of the Scratch GUI. They are colour-coded, so remember the colours. Find out
what they are and complete their names in the table below:
M... C...
L... S...
S... O...
P... V...
Now, follow these simple steps to make your cat talk:
1
Click on the cat sprite in the
Sprites List (bottom right) to
make sure that it’s selected.
2
Click on the “Looks” button
in the Blocks Palette to make
the Looks blocks appear.
3
Click on the block labelled
“say [Hello] for [2] seconds”
and drag it to the Scripts tab.
4
Replace “Hello” with “Hello,
World”. Double-click the
block and your cat should
say: “Hello, World.
