We give you one example of an Event. Nothing happens in computerland without an event, and in Scratch, an event is always this shape and this colour.

It tells your game when to start. The event in the 10-block challenge is “When this sprite is clicked” which means the game will start when the sprite (in this case, the default one of the Cat) is clicked.

We have given you two control blocks. The control blocks is where the computational thinking rubber hits the road.

It allows your algorithm to have a flow that is not just linear.

In our example, we have given you a repeat loop (so everything you put inside the mouth of the loop repeats) and a simple pause command.

In Scratch, all control blocks are this colour

We have given you four look blocks. A look block controls the looks of your sprites (characters) It can also give it a speech bubble.

We have given you four to play with.

In Scratch, all look blocks are this colour.

The bane of all teachers who teach using Scratch. There is a group of Sound blocks which give your sprites (characters) sounds.

In Scratch, all sound blocks are this colour.

Motion blocks help move your sprites (characters). You can use coordinates, in combination to values.

These are the two we give you to play with, but have a look at the others.

In Scratch, all motion blocks are this colour.
